Each bidder is responsible for review of the Contract Documents and any informational documents provided “For Reference Only,” e.g., Wilson Park Basketball Court INSTRUCTIONS TO BIDDERS Project No. 2022-11 Page 5 as-builts, technical reports, test data, and the like. A bidder is responsible for notifying City of any errors, omissions, inconsistencies, or conflicts it discovers in the Contract Documents, acting solely in its capacity as a contractor and subject to the limitations of Public Contract Code § 1104. Notification of any such errors, omissions, inconsistencies, or conflicts must be submitted in writing to the City no later than five Working Days before the scheduled bid opening. (See Section 5, above.) City expressly disclaims responsibility for assumptions a bidder might draw from the presence or absence of information provided by City. 6.3 Project Site. Questions regarding the availability of soil test data, water table elevations, and the like should be submitted to the City in writing, as specified in Section 5, above. Any subsurface exploration at the Project site must be done at the bidder’s expense, but only with prior written authorization from City. All soil data and analyses available for inspection or provided in the Contract Documents apply only to the test hole locations. Any water table elevation indicated by a soil test report existed on the date the test hole was drilled. The bidder is responsible for determining and allowing for any differing soil or water table conditions during construction. Because groundwater levels may fluctuate, difference(s) in elevation between ground water shown in soil boring logs and ground water actually encountered during Project construction will not be considered changed Project site conditions. Actual locations and depths must be determined by bidder’s field investigation. The bidder may request access to underlying or background information on the Project site in City’s possession that is necessary for the bidder to form its own conclusions, including, if available, record drawings or other documents indicating the location of subsurface lines, utilities, or other structures. 6.4 Utility Company Standards. The Project must be completed in a manner that satisfies the standards and requirements of any affected utility companies or agencies (collectively, “utility owners”). The successful bidder may be required by the third party utility owners to provide detailed plans prepared by a California registered civil engineer showing the necessary temporary support of the utilities during coordinated construction work. Bidders are directed to contact the affected third party utility owners about their requirements before submitting a Bid Proposal. 7. Bidders Interested in More Than One Bid. No person, firm, or corporation may submit or be a party to more than one Bid Proposal unless alternate bids are specifically called for. However, a person, firm, or corporation that has submitted a subcontract proposal or quote to a bidder may submit subcontract proposals or quotes to other bidders. 8. Addenda. Any addenda issued prior to the bid opening are part of the Contract Documents. Subject to the limitations of Public Contract Code § 4104.5, City reserves the right to issue addenda prior to bid time. Each bidder is solely responsible for ensuring it has received and reviewed all addenda prior to submitting its bid. Bidders should check City’s website periodically for any addenda or updates on the Project at: http://www.apps.cupertino.org/bidmanagment/index.aspx. 9. Brand Designations and “Or Equal” Substitutions. Any specification designating a material, product, thing, or service by specific brand or trade name, followed by the words “or equal,” is intended only to indicate quality and type of item desired, and bidders may request use of any equal material, product, thing, or service. All data substantiating the proposed substitute as an equal item must be submitted with the written request for substitution. A request for substitution must be submitted within 35 days after Notice of Potential Award unless otherwise provided in the Contract Documents. This provision does not apply to materials, products, things, or services that may lawfully be designated by a specific brand or trade name under Public Contract Code § 3400(c). Wilson Park Basketball Court INSTRUCTIONS TO BIDDERS Project No. 2022-11 Page 6 10. Bid Protest. Any bid protest against another bidder must be submitted in writing and received by City at 10300 Torre Avenue, Cupertino CA 95014 or sent via email at susanm@cupertino.org before 5:00 p.m. no later than two Working Days following the date upon which the City posts the bid results (“Bid Protest Deadline”) and must comply with the following requirements: 10.1 General. Only a bidder who has actually submitted a Bid Proposal is eligible to submit a bid protest against another bidder. Subcontractors are not eligible to submit bid protests. A bidder may not rely on the bid protest submitted by another bidder, but must timely pursue its own protest. If required by City, the protesting bidder must submit a non-refundable fee in the amount specified by City, based upon City’s reasonable costs to administer the bid protest. Any such fee must be submitted to City no later than the Bid Protest Deadline, unless otherwise specified. For purposes of this Section 10, a “Working Day” means a day that City is open for normal business, and excludes weekends and holidays observed by City. Pursuant to Public Contract Code § 4104, inadvertent omission of a Subcontractor’s DIR registration number on the Subcontractor List form is not grounds for a bid protest, provided it is corrected within 24 hours of the bid opening or as otherwise provided under Labor Code § 1771.1(b). 10.2 Protest Contents. The bid protest must contain a complete statement of the basis for the protest and must include all supporting documentation. Material submitted after the Bid Protest Deadline will not be considered. The protest must refer to the specific portion or portions of the Contract Documents upon which the protest is based. The protest must include the name, address, email address, and telephone number of the protesting bidder and any person submitting the protest on behalf of or as an authorized representative of the protesting bidder. 10.3 Copy to Protested Bidder. Upon submission of its bid protest to City, the protesting bidder must also concurrently transmit the protest and all supporting documents to the protested bidder, and to any other bidder who has a reasonable prospect of receiving an award depending upon the outcome of the protest, by email or hand delivery to ensure delivery before the Bid Protest Deadline. 10.4 Response to Protest. The protested bidder may submit a written response to the protest, provided the response is received by City before 5:00 p.m., within two Working Days after the Bid Protest Deadline or after actual receipt of the bid protest, whichever is sooner (the “Response Deadline”). The response must attach all supporting documentation. Material submitted after the Response Deadline will not be considered. The response must include the name, address, email address, and telephone number of the person responding on behalf of or representing the protested bidder if different from the protested bidder. 10.5 Copy to Protesting Bidder. Upon submission of its response to the bid protest to the City, the protested bidder must also concurrently transmit by email or hand delivery, by or before the Response Deadline, a copy of its response and all supporting documents to the protesting bidder and to any other bidder who has a reasonable prospect of receiving an award depending upon the outcome of the protest. 10.6 Exclusive Remedy. The procedure and time limits set forth in this Section are mandatory and are the bidder’s sole and exclusive remedy in the event of a bid protest. A bidder’s failure to comply with these procedures will constitute a waiver Wilson Park Basketball Court INSTRUCTIONS TO BIDDERS Project No. 2022-11 Page 7 of any right to further pursue a bid protest, including filing a Government Code Claim or initiation of legal proceedings. 10.7 Right to Award. City reserves the right, acting in its sole discretion, to reject any bid protest that it determines lacks merit, to award the Contract to the bidder it has determined to be the responsible bidder submitting the lowest responsive bid, and to issue a Notice to Proceed with the Work notwithstanding any pending or continuing challenge to its determination. 11. Reservation of Rights. City reserves the unfettered right, acting in its sole discretion, to waive or to decline to waive any immaterial bid irregularities; to accept or reject any or all bids; to cancel or reschedule the bid; to postpone or abandon the Project entirely; or to perform all or part of the Work with its own forces. The Contract will be awarded, if at all, within 60 days after opening of bids or as otherwise specified in the Special Conditions, to the responsible bidder that submitted the lowest responsive bid. Any planned start date for the Project represents the City’s expectations at the time the Notice Inviting Bids was first issued. City is not bound to issue a Notice to Proceed by or before such planned start date, and it reserves the right to issue the Notice to Proceed when the City determines, in its sole discretion, the appropriate time for commencing the Work. The City expressly disclaims responsibility for any assumptions a bidder might draw from the presence or absence of information provided by the City in any form. Each bidder is solely responsible for its costs to prepare and submit a bid, including site investigation costs. 12. Bonds. Within ten calendar days following City’s issuance of the Notice of Potential Award to the apparent low bidder, the bidder must submit payment and performance bonds to City as specified in the Contract Documents using the bond forms included in the Contract Documents. All required bonds must be calculated on the maximum total Contract Price as awarded, including additive alternates, if applicable. 13. License(s). The successful bidder and its Subcontractor(s) must possess the California contractor’s license(s) in the classification(s) required by law to perform the Work. The successful bidder must also obtain a City business license within 5 days following City’s issuance of the Notice of Potential Award. Subcontractors must also obtain a City business license before performing any Work. 14. Ineligible Subcontractor. Any Subcontractor who is ineligible to perform work on a public works project under Labor Code §§ 1777.1 or 1777.7 is prohibited from performing work on the Project. 15. Safety Orders. If the Project includes construction of a pipeline, sewer, sewage disposal system, boring and jacking pits, or similar trenches or open excavations, which are five feet or deeper, each bid must include a bid item for adequate sheeting, shoring, and bracing, or equivalent method, for the protection of life or limb, which comply with safety orders as required by Labor Code § 6707. 16. Subcontractor Work Limits. The prime contractor must perform at least 51% of the Work on the Project, calculated as a percentage of the base bid price, with its own forces, except for any Work identified as “Specialty Work” in the Contract Documents. The total bid amount for any such Specialty Work, as shown on the Bid Schedule, may be deducted from the base bid price before computing the 51% self-performance requirement. The remaining Work may be performed by qualified Subcontractor(s). 17. Additive and Deductive Alternates. As required by Public Contract Code § 20103.8, if this bid solicitation includes additive or deductive items, the method checked below will be used to determine the lowest bid. If no method is checked, subparagraph (A) will be used to Wilson Park Basketball Court INSTRUCTIONS TO BIDDERS Project No. 2022-11 Page 8 determine the lowest bid. City retains the right to add to or deduct from the Contract any of the additive or deductive alternates included in the Bid Proposal. (A) The lowest bid will be the lowest bid price on the base contract without consideration of the prices on the additive or deductive items. X (B) The lowest bid will be the lowest total of the bid prices on the base contract and those additive or deductive items that were specifically identified in the bid solicitation or Bid Proposal as being used for the purpose of determining the lowest bid price. _____ (C) The lowest bid will be the lowest total of the bid prices on the base contract and those additive or deductive items taken in order from a specifically identified list of those items that, when in the solicitation, and added to, or subtracted from, the base contract, are less than, or equal to, a funding amount publicly disclosed by City before the first bid is opened. _____ (D) The lowest bid will be determined in a manner that prevents any information that would identify any of the bidders or the proposed subcontractors or suppliers from being revealed to City before the ranking of all bidders from lowest to highest has been determined. 18. Bid Schedule. Each bidder must complete the Bid Schedule form with unit prices as indicated, and submit the completed Bid Schedule with its Bid Proposal. 18.1 Incorrect Totals. In the event a computational error for any bid item (base bid or alternate) results in an incorrect extended total for that item, the submitted base bid or bid alternate total will be adjusted to reflect the corrected amount as the product of the estimated quantity and the unit cost. In the event of a discrepancy between the actual total of the itemized or unit prices shown on the Bid Schedule for the base bid, and the amount entered as the base bid on the Bid Proposal form, the actual total of the itemized or unit prices shown on the Bid Schedule for the base bid will be deemed the base bid price. Likewise, in the event of a discrepancy between the actual total of the itemized or unit prices shown on the Bid Schedule for any bid alternate, and the amount entered for the alternate on the Bid Proposal form, the actual total of the itemized prices shown on the Bid Schedule for that alternate will be deemed the alternate price. Nothing in this provision is intended to prevent a bidder from requesting to withdraw its bid for material error under Public Contract Code § 5100 et seq. 18.2 Estimated Quantities. The quantities shown on the Bid Schedule are estimated and the actual quantities required to perform the Work may be greater or less than the estimated amount. The Contract Price will be adjusted to reflect the actual quantities required for the Work based on the itemized or unit prices provided in the Bid Schedule, with no allowance for anticipated profit for quantities that are deleted or decreased, and no increase in the unit price, and without regard to the percentage increase or decrease of the estimated quantity and the actual quantity. 19. Bidder’s Questionnaire. A completed, signed Bidder’s Questionnaire using the form provided with the Contract Documents and including all required attachments must be submitted within 48 hours following a request by City. A bid that does not fully comply with this requirement may be rejected as nonresponsive. A bidder who submits a Bidder’s Questionnaire which is subsequently determined to contain false or misleading information, or material omissions, may be disqualified as non-responsible.

Contractor is solely responsible for and required to exercise full control over the Work, including the construction means, methods, techniques, sequences, procedures, safety precautions and programs, and coordination of all portions of the Work with that of all other contractors and Subcontractors, except to the Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 32 extent that the Contract Documents provide other specific instructions. Contractor’s responsibilities extend to any plan, method or sequence suggested, but not required by City or specified in the Contract Documents. From the date of commencement of the Work until either the date on which City formally accepts the Project or the effective date of termination of the Contract, whichever is later, Contractor bears all risks of injury or damage to the Work and the materials and equipment delivered to any Worksite, by any cause including fire, earthquake, wind, weather, vandalism or theft. (C) Project Administration. Contractor must provide sufficient and competent administration, staff, and skilled workforce necessary to perform and timely complete the Work in accordance with the Contract Documents. Before starting the Work, Contractor must designate in writing and provide complete contact information, including telephone numbers and email address, for the officer or employee in Contractor’s organization who is to serve as Contractor’s primary representative for the Project, and who has authority to act on Contractor’s behalf.

The superintendent must have full authority to act and communicate on behalf of Contractor, and Contractor will be bound by the superintendent’s communications to City. City’s approval of the superintendent is required before the Work commences. If City is not satisfied with the superintendent’s performance, City may request a qualified replacement of the superintendent. Failure to comply may result in temporary suspension of the Work, at Contractor’s sole expense and with no extension of Contract Time, until an approved superintendent is physically present to supervise the Work. Contractor must provide written notice to City, as soon as practicable, before replacing the superintendent. (E) Standards. Contractor must, at all times, ensure that the Work is performed in an efficient, skillful manner following best practices and in full compliance with the Contract Documents and Laws and applicable manufacturer’s recommendations.

(I) Correction of Defects. Contractor must promptly correct, at Contractor’s sole expense, any Work that is determined by City to be deficient or defective in any way, including workmanship, materials, parts or equipment. Workmanship, materials, parts or equipment that do not conform to the requirements under the Plans, Specifications and every other Contract Document, as determined by City, will be considered defective and subject to rejection. Contractor must also promptly correct, at Contractor’s sole expense, any Work performed beyond the lines and grades shown on the Plans or established by City, and any Extra Work performed without City’s prior written approval. If Contractor fails to correct or to take reasonable steps toward correcting defective Work within five days following notice from City, or within the time specified in City’s notice to correct, City may elect to have the defective Work corrected by its own forces or by a third party, in which case the cost of correction will be deducted from the Contract Price. If City elects to correct defective Work due to Contractor’s failure or refusal to do so, City or its agents will have the right to take possession of and use any equipment, supplies, or materials available at the Project site or any Worksite on City property, in order to effectuate the correction, at no extra cost to City. Contractor’s warranty obligations under Section 11.2, Warranty, will not be waived nor limited by City’s actions to correct defective Work under these circumstances. Alternatively, City may elect to retain defective Work, and deduct the difference in value, as determined by the Engineer, from payments otherwise due to Contractor. This paragraph applies to any defective Work performed by Contractor during the one-year warranty period under Section 11.2. (J) Contractor’s Records. Contractor must maintain all of its records relating to the Project in any form, including paper documents, photos, videos, electronic records, approved samples, and the construction records required pursuant to paragraph (G), above.

Contractor’s failure to comply with this provision as to any claimed cost operates as a waiver of any rights to recover the claimed cost. (2) Contractor must continue to maintain its Project-related records in an organized manner for a period of five years after City’s acceptance of the Project or following Contract termination, whichever occurs first. Subject to prior notice to Contractor, City is entitled to inspect or audit any of Contractor’s Project records Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 34 relating to the Project or to investigate Contractor’s plant or equipment during Contractor’s normal business hours.

These documents must be available to City for reference at all times during construction of the Project. 2.3 Subcontractors. (A) General. All Work which is not performed by Contractor with its own forces must be performed by Subcontractors. City reserves the right to approve or reject any and all Subcontractors proposed to perform the Work, for reasons including the subcontractor’s poor reputation, lack of relevant experience, financial instability, and lack of technical ability or adequate trained workforce. Each Subcontractor must obtain a City business license before performing any Work. (B) Contractual Obligations. Contractor must require each Subcontractor to comply with the provisions of the Contract Documents as they apply to the Subcontractor’s portion(s) of the Work, including the generally applicable terms of the Contract Documents, and to likewise bind their subcontractors. Contractor will provide that the rights that each Subcontractor may have against any manufacturer or supplier for breach of warranty or guarantee relating to items provided by the Subcontractor for the Project, will be assigned to City. Nothing in these Contract Documents creates a contractual relationship between a Subcontractor and City, but City is deemed to be a third-party beneficiary of the contract between Contractor and each Subcontractor. (C) Termination. If the Contract is terminated, each Subcontractor’s agreement must be assigned by Contractor to City, subject to the prior rights of any surety, but only if and to the extent that City accepts, in writing, the assignment by written notification, and assumes all rights and obligations of Contractor pursuant to each such subcontract agreement. (D) Substitution of Subcontractor. If Contractor requests substitution of a listed Subcontractor under Public Contract Code § 4107, Contractor is solely responsible for all costs City incurs in responding to the request, including legal fees and costs to conduct a hearing, and any increased subcontract cost to perform the Work that was to be performed by the listed Subcontractor. If City determines that a Subcontractor is unacceptable to City based on the Subcontractor’s failure to satisfactorily perform its Work, or for any of the grounds for substitution listed in Public Contract Code § 4107(a), City may request removal of the Subcontractor from the Project. Upon receipt of a written request from City to remove a Subcontractor pursuant to this paragraph, Contractor will immediately remove the Subcontractor from the Project and, at no further cost to City, will either (1) self-perform the remaining Work to the extent that Contractor is duly licensed and qualified to do so, or (2) substitute a Subcontractor that is acceptable to City, in compliance with Public Contract Code § 4107, as applicable. 2.4 Coordination of Work. (A) Concurrent Work. City reserves the right to perform, have performed, or permit performance of other work on or adjacent to the Project site while the Work is being performed for the Project. Contractor is responsible for coordinating its Work with other Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 35 work being performed on or adjacent to the Project site, including by any utility companies or agencies, and must avoid hindering, delaying, or interfering with the work of other contractors, individuals, or entities, and must ensure safe and reasonable site access and use as required or authorized by City. To the full extent permitted by law, Contractor must hold harmless and indemnify City against any and all claims arising from or related to Contractor’s avoidable, negligent, or willful hindrance of, delay to, or interference with the work of any utility company or agency or another contractor or subcontractor. (B) Coordination. If Contractor’s Work will connect or interface with work performed by others, Contractor is responsible for independently measuring and visually inspecting such work to ensure a correct connection and interface. Contractor is responsible for any failure by Contractor or its Subcontractors to confirm measurements before proceeding with connecting Work. Before proceeding with any portion of the Work affected by the construction or operations of others, Contractor must give the Project Manager prompt written notification of any defects Contractor discovers which will prevent the proper execution of the Work. Failure to give notice of any known or reasonably discoverable defects will be deemed acknowledgement by Contractor that the work of others is not defective and will not prevent the proper execution of the Work. Contractor must also promptly notify City if work performed by others, including work or activities performed by City’s own forces, is operating to hinder, delay, or interfere with Contractor’s timely performance of the Work. City reserves the right to backcharge Contractor for any additional costs incurred due to Contractor’s failure to comply with the requirements in this Section 2.4. 2.5 Submittals. Unless otherwise specified, Contractor must submit to the Engineer for review and acceptance, all schedules, Shop Drawings, samples, product data, and similar submittals required by the Contract Documents, or upon request by the Engineer. Unless otherwise specified, all submittals, including Requests for Information, are subject to the general provisions of this Section, as well as specific submittal requirements that may be included elsewhere in the Contract Documents, including the Special Conditions or Specifications. The Engineer may require submission of a submittal schedule at or before a pre-construction conference, as may be specified in the Notice to Proceed. (A) General. Contractor is responsible for ensuring that its submittals are accurate and conform to the Contract Documents. (B) Time and Manner of Submission. Contractor must ensure that its submittals are prepared and delivered in a manner consistent with the current City-accepted schedule for the Work and within the applicable time specified in the Contract Documents, or if no time is specified, in such time and sequence so as not to delay the performance of the Work or completion of the Project. (C) Required Contents. Each submittal must include the Project name and contract number, Contractor’s name and address, the name and address of any Subcontractor or supplier involved with the submittal, the date, and references to applicable Specification section(s) and/or drawing and detail number(s). (D) Required Corrections. If corrections are required, Contractor must promptly make and submit any required corrections as specified in full conformance with the requirements of this Section, or other requirements that apply to that submittal. (E) Effect of Review and Acceptance. Review and acceptance of a submittal by City will not relieve Contractor from complying with the requirements of the Contract Documents. Contractor is responsible for any errors in any submittal, and review or acceptance of a submittal by City is not an assumption of risk or liability by City. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 36 (F) Enforcement. Any Work performed or any material furnished, installed, fabricated or used without City’s prior acceptance of a required submittal is performed or provided at Contractor’s risk, and Contractor may be required to bear the costs incident thereto, including the cost of removing and replacing such Work, repairs to other affected portions of the Work or material, and the cost of additional time or services required of City, including costs for the Design Professional, Project Manager, or Inspector. (G) Excessive RFIs. A RFI will be considered excessive or unnecessary if City determines that the explanation or response to the RFI is clearly and unambiguously discernable from the Contract Documents. City’s costs to review and respond to excessive or unnecessary RFIs may be deducted from payments otherwise due to Contractor. 2.6 Shop Drawings. When Shop Drawings are required by the Specifications or requested by the Engineer, they must be prepared according to best practices at Contractor’s expense. The Shop Drawings must be of a size and scale to clearly show all necessary details. Unless otherwise specified by City, Shop Drawings must be provided to the Engineer for review and acceptance at least 30 days before the Work will be performed. If City requires changes, the corrected Shop Drawings must be resubmitted to the Engineer for review within the time specified by the Engineer. For all Project components requiring Shop Drawings, Contractor will not furnish materials or perform any Work until the Shop Drawings for those components are accepted by City. Contractor is responsible for any errors or omissions in the Shop Drawings, shop fits and field corrections; any deviations from the Contract Documents; and for the results obtained by the use of Shop Drawings. Acceptance of Shop Drawings by City does not relieve Contractor of Contractor’s responsibility. 2.7 Access to Work. Contractor must afford prompt and safe access to any Worksite by City and its employees, agents, or consultants authorized by City; and upon request by City, Contractor must promptly arrange for City representatives to visit or inspect manufacturing sites or fabrication facilities for items to be incorporated into the Work. 2.8 Personnel. Contractor and its Subcontractors must employ only competent and skillful personnel to perform the Work. Contractor and its Subcontractor’s supervisors, security or safety personnel, and employees who have unescorted access to the Project site must possess proficiency in English sufficient to read, understand, receive, and implement oral or written communications or instructions relating to their respective job functions, including safety and security requirements. Upon written notification from the Engineer, Contractor and its Subcontractors must immediately discharge any personnel who are incompetent, disorderly, disruptive, threatening, abusive, or profane, or otherwise refuse or fail to comply with the requirements of the Contract Documents or Laws, including Laws pertaining to health and safety. Any such discharged personnel, may not be re- employed or permitted on the Project in any capacity without City’s prior written consent. Article 3 - Contract Documents 3.1 Interpretation of Contract Documents. (A) Plans and Specifications. The Plans and Specifications included in the Contract Documents are complementary. If Work is shown on one but not on the other, Contractor must perform the Work as though fully described on both, consistent with the Contract Documents and reasonably inferable from them as being necessary to produce the indicated results. The Plans and Specifications are deemed to include and require everything necessary and reasonably incidental to completion of the Work, whether or Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 37 not particularly mentioned or shown. Contractor must perform all Work and services and supply all things reasonably related to and inferable from the Contract Documents. In the event of a conflict between the Plans and Specifications, the Specifications will control, unless the drawing(s) at issue are dated later than the Specification(s) at issue. Detailed drawings take precedence over general drawings, and large-scale drawings take precedence over smaller scale drawings. Any arrangement or division of the Plans and Specifications into sections is for convenience and is not intended to limit the Work required by separate trades. A conclusion presented in the Plans or Specifications is only a recommendation. Actual locations and depths must be determined by Contractor’s field investigation. Contractor may request access to underlying or background information in City’s possession that is necessary for Contractor to form its own conclusions. (B) Duty to Notify and Seek Direction. If Contractor becomes aware of a changed condition in the Project, or of any ambiguity, conflict, inconsistency, discrepancy, omission, or error in the Contract Documents, including the Plans or Specifications, Contractor must promptly submit a Request for Information to the Engineer and wait for a response from City before proceeding further with the related Work. The RFI must notify City of the issue and request clarification, interpretation or direction. The Engineer’s clarification, interpretation or direction will be final and binding on Contractor. If Contractor proceeds with the related Work before obtaining City’s response, Contractor will be responsible for any resulting costs, including the cost of correcting any incorrect or defective Work that results. Timely submission of a clear and complete RFI is essential to avoiding delay. Delay resulting from Contractor’s failure to submit a timely and complete RFI to the Engineer is Non-Excusable Delay. If Contractor believes that City’s response to an RFI justifies a change to the Contract Price or Contract Time, Contractor must perform the Work as directed, but may submit a timely Change Order request in accordance with the Contract Documents. (See Article 5 and 6.) (C) Figures and Dimensions. Figures control over scaled dimensions. (D) Technical or Trade Terms. Any terms that have well-known technical or trade meanings will be interpreted in accordance with those meanings, unless otherwise specifically defined in the Contract Documents. (E) Measurements. Contractor must verify all relevant measurements in the Contract Documents and at the Project site before ordering any material or performing any Work, and will be responsible for the correctness of those measurements or for costs that could have been avoided by independently verifying measurements. (F) Compliance with Laws. The Contract Documents are intended to comply with Laws and will be interpreted to comply with Laws. 3.2 Order of Precedence. Information included in one Contract Document but not in another will not be considered a conflict or inconsistency. Unless otherwise specified in the Special Conditions, in case of any conflict or inconsistency among the Contract Documents, the following order of precedence will apply, beginning from highest to lowest, with the most recent version taking precedent over an earlier version: (A) Change Orders; (B) Addenda; (C) Contract; (D) Notice to Proceed; (E) Attachment B – Federal Contract Requirements (only if used); (F) Special Conditions; (G) General Conditions; (H) Payment and Performance Bonds; Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 38 (I) Specifications; (J) Plans; (K) Notice of Potential Award; (L) Notice Inviting Bids; (M) Attachment A – Federal Bidding Requirements (only if used); (N) Instructions to Bidders; (O) Contractor’s Bid Proposal and attachments; (P) the City’s standard specifications, as applicable; and (Q) Any generic documents prepared by and on behalf of a third party, that were not prepared specifically for this Project, such as the Caltrans Standard Specifications or Caltrans Special Provisions. 3.3 Caltrans Standard Specifications. Any reference to or incorporation of the Standard Specifications of the State of California, Department of Transportation (“Caltrans”), including “Standard Specifications,” “Caltrans Specifications,” “State Specifications,” or “CSS,” means the most current edition of Caltrans’ Standard Specifications, unless otherwise specified (“Caltrans Standard Specifications”), including the most current amendments as of the date that Contractor’s bid was submitted for this Project. The following provisions apply to use of or reference to the Caltrans Standard Specifications or Special Provisions: (A) Limitations. The “General Provisions” of the Caltrans Standard Specifications, i.e., sections 1 through 9, do not apply to these Contract Documents with the exception of any specific provisions, if any, which are expressly stated to apply to these Contract Documents. (B) Conflicts or Inconsistencies. If there is a conflict or inconsistency between any provision in the Caltrans Standard Specifications or Special Provisions and a provision of these Contract Documents, as determined by City, the provision in the Contract Documents will govern. (C) Meanings. Terms used in the Caltrans Standard Specifications or Special Provisions are to be interpreted as follows: (1) Any reference to the “Engineer” is deemed to mean the City Engineer. (2) Any reference to the “Special Provisions” is deemed to mean the Special Conditions, unless the Caltrans Special Provisions are expressly included in the Contract Documents listed in Section 2 of the Contract. (3) Any reference to the “Department” or “State” is deemed to mean City. 3.4 For Reference Only. Contractor is responsible for the careful review of any document, study, or report provided by City or appended to the Contract Documents solely for informational purposes and identified as “For Reference Only.” Nothing in any document, study, or report so appended and identified is intended to supplement, alter, or void any provision of the Contract Documents. Contractor is advised that City or its representatives may be guided by information or recommendations included in such reference documents, particularly when making determinations as to the acceptability of proposed materials, methods, or changes in the Work. Any record drawings or similar final or accepted drawings or maps that are not part of the Contract Documents are deemed to be For Reference Only. The provisions of the Contract Documents are not modified by any perceived or actual conflict with provisions in any document that is provided For Reference Only. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 39 3.5 Current Versions. Unless otherwise specified by City, any reference to standard specifications, technical specifications, or any City or state codes or regulations means the latest specification, code or regulation in effect at the time the Contract is signed. 3.6 Conformed Copies. If City prepares a conformed set of the Contract Documents following award of the Contract, it will provide Contractor with two hard copy (paper) sets and one copy of the electronic file in PDF format. It is Contractor’s responsibility to ensure that all Subcontractors, including fabricators, are provided with the conformed set of the Contract Documents at Contractor’s sole expense. 3.7 Ownership. No portion of the Contract Documents may be used for any purpose other than construction of the Project, without prior written consent from City. Contractor is deemed to have conveyed the copyright in any designs, drawings, specifications, Shop Drawings, or other documents (in paper or electronic form) developed by Contractor for the Project, and City will retain all rights to such works, including the right to possession. Article 4 - Bonds, Indemnity, and Insurance 4.1 Payment and Performance Bonds. Within ten days following issuance of the Notice of Potential Award, Contractor is required to provide a payment bond and a performance bond, each in the penal sum of not less than 100% of the Contract Price, and each executed by Contractor and its surety using the bond forms included with the Contract Documents. (A) Surety. Each bond must be issued and executed by a surety admitted in California. If an issuing surety cancels the bond or becomes insolvent, within seven days following written notice from City, Contractor must substitute a surety acceptable to City. If Contractor fails to substitute an acceptable surety within the specified time, City may, at its sole discretion, withhold payment from Contractor until the surety is replaced to City’s satisfaction, or terminate the Contract for default. (B) Supplemental Bonds for Increase in Contract Price. If the Contract Price increases during construction by five percent or more over the original Contract Price, Contractor must provide supplemental or replacement bonds within ten days of written notice from City pursuant to this Section, covering 100% of the increased Contract Price and using the bond forms included with the Contract Documents. 4.2 Indemnity. To the fullest extent permitted by law, Contractor must indemnify, defend, and hold harmless City, its Council, officers, officials, employees, agents, volunteers, and consultants (individually, an “Indemnitee,” and collectively the “Indemnitees”) from and against any and all liability, loss, damage, claims, causes of action, demands, charges, fines, costs, and expenses (including, without limitation, attorney fees, expert witness fees, paralegal fees, and fees and costs of litigation or arbitration) (collectively, “Liability”) of every nature arising out of or in connection with the acts or omissions of Contractor, its employees, Subcontractors, representatives, or agents, in bidding or performing the Work or in failing to comply with any obligation of Contractor under the Contract, except such Liability caused by the active negligence, sole negligence, or willful misconduct of an Indemnitee. This indemnity requirement applies to any Liability arising from alleged defects in the content or manner of submission of Contractor’s bid for the Contract. Contractor’s failure or refusal to timely accept a tender of defense pursuant to this Contract will be deemed a material breach of the Contract. City will timely notify Contractor upon receipt of any third-party claim relating to the Contract, as required by Public Contract Code § 9201. Contractor waives any right to express or implied indemnity against any Indemnitee. Contractor’s indemnity obligations under this Contract will survive the expiration or any early termination of the Contract. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 40 4.3 Insurance. No later than ten days following issuance of the Notice of Potential Award, Contractor must procure and provide proof of the insurance coverage required by this Section in the form of certificates and endorsements acceptable to City. The required insurance must cover the activities of Contractor and its Subcontractors relating to or arising from the performance of the Work, and must remain in full force and effect at all times during the period covered by the Contract, through the date of City’s acceptance of the Project. All required insurance must be issued by a company licensed to do business in the State of California, and each such insurer must have an A.M. Best’s financial strength rating of “A” or better and a financial size rating of “VIII” or better. If Contractor fails to provide any of the required coverage in full compliance with the requirements of the Contract Documents, City may, at its sole discretion, purchase such coverage at Contractor’s expense and deduct the cost from payments due to Contractor, or terminate the Contract for default. The procurement of the required insurance will not be construed to limit Contractor’s liability under this Contract or to fulfill Contractor’s indemnification obligations under this Contract. (A) Policies and Limits. The following insurance policies and limits are required for this Contract, unless otherwise specified in the Special Conditions: (1) Commercial General Liability (“CGL”) Insurance: The CGL insurance policy must be issued on an occurrence basis, written on a comprehensive general liability form, and must include coverage for liability arising from Contractor’s or its Subcontractor’s acts or omissions in the performance of the Work, including contractor’s protected coverage, contractual liability, products and completed operations, and broad form property damage, with limits of at least $2,000,000 per occurrence and at least $4,000,000 general aggregate. The CGL insurance coverage may be arranged under a single policy for the full limits required or by a combination of underlying policies with the balance provided by excess or umbrella policies, provided each such policy complies with the requirements set forth in this Section, including required endorsements. (2) Automobile Liability Insurance: The automobile liability insurance policy must provide coverage of at least $2,000,000 combined single-limit per accident for bodily injury, death, or property damage, including hired and non-owned auto liability. (3) Workers’ Compensation Insurance and Employer’s Liability: The workers’ compensation and employer’s liability insurance policy must comply with the requirements of the California Labor Code, providing coverage of at least $1,000,000 or as otherwise required by the statute. If Contractor is self-insured, Contractor must provide its Certificate of Permission to Self-Insure, duly authorized by the DIR. (4) Pollution Liability Insurance: The pollution liability insurance policy must be issued on an occurrence basis, providing coverage of at least $2,000,000 for all loss arising out of claims for bodily injury, death, property damage, or environmental damage caused by pollution conditions resulting from the Work. (5) Builder’s Risk Insurance: The builder’s risk insurance policy must be issued on an occurrence basis, for all-risk or “all perils” coverage on a 100% completed value basis on the insurable portion of the Project for the benefit of City. (B) Notice. Each certificate of insurance must state that the coverage afforded by the policy or policies will not be reduced, cancelled or allowed to expire without at least Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 41 30 days written notice to City, unless due to non-payment of premiums, in which case ten days written notice must be made to City. (C) Waiver of Subrogation. Each required policy must include an endorsement providing that the carrier will waive any right of subrogation it may have against City. (D) Required Endorsements. The CGL policy, automobile liability policy, pollution liability policy, and builder’s risk policy must include the following specific endorsements: (1) The City, including its Council, officials, officers, employees, agents, volunteers and consultants (collectively, “Additional Insured”) must be named as an additional insured for all liability arising out of the operations by or on behalf of the named insured, and the policy must protect the Additional Insured against any and all liability for personal injury, death or property damage or destruction arising directly or indirectly in the performance of the Contract. The additional insured endorsement must be provided using ISO form CG 20 10 11 85 or an equivalent form approved by the City. (2) The inclusion of more than one insured will not operate to impair the rights of one insured against another, and the coverages afforded will apply as though separate policies have been issued to each insured. (3) The insurance provided by Contractor is primary and no insurance held or owned by any Additional Insured may be called upon to contribute to a loss. (4) This policy does not exclude explosion, collapse, underground excavation hazard, or removal of lateral support. (E) Contractor’s Responsibilities. This Section 4.3 establishes the minimum requirements for Contractor’s insurance coverage in relation to this Project, but is not intended to limit Contractor’s ability to procure additional or greater coverage. Contractor is responsible for its own risk assessment and needs and is encouraged to consult its insurance provider to determine what coverage it may wish to carry beyond the minimum requirements of this Section. Contractor is solely responsible for the cost of its insurance coverage, including premium payments, deductibles, or self-insured retentions, and no Additional Insured will be responsible or liable for any of the cost of Contractor’s insurance coverage. (F) Deductibles and Self-Insured Retentions. Any deductibles or self-insured retentions that apply to the required insurance (collectively, “deductibles”) in excess of $100,000 are subject to approval by the City’s Risk Manager, acting in his or her sole discretion, and must be declared by Contractor when it submits its certificates of insurance and endorsements pursuant to this Section 4.3. If the City’s Risk Manager determines that the deductibles are unacceptably high, at City’s option, Contractor must either reduce or eliminate the deductibles as they apply to City and all required Additional Insured; or must provide a financial guarantee, to City’s satisfaction, guaranteeing payment of losses and related investigation, claim administration, and legal expenses. (G) Subcontractors. Contractor must ensure that each Subcontractor is required to maintain the same insurance coverage required under this Section 4.3, with respect to its performance of Work on the Project, including those requirements related to the Additional Insureds and waiver of subrogation, but excluding pollution liability or builder’s risk insurance unless otherwise specified in the Special Conditions. A Subcontractor may be eligible for reduced insurance coverage or limits, but only to the extent approved in writing in advance by the City’s Risk Manager. Contractor must confirm that each Subcontractor has complied with these insurance requirements before the Subcontractor Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 42 is permitted to begin Work on the Project. Upon request by the City, Contractor must provide certificates and endorsements submitted by each Subcontractor to prove compliance with this requirement. The insurance requirements for Subcontractors do not replace or limit the Contractor’s insurance obligations. Article 5 - Contract Time 5.1 Time is of the Essence. Time is of the essence in Contractor’s performance and completion of the Work, and Contractor must diligently prosecute the Work and complete it within the Contract Time. (A) General. Contractor must commence the Work on the date indicated in the Notice to Proceed and must fully complete the Work in strict compliance with all requirements of the Contract Documents and within the Contract Time. Contractor may not begin performing the Work before the date specified in the Notice to Proceed. (B) Authorization. Contractor is not entitled to compensation or credit for any Work performed before the date specified in the Notice to Proceed, with the exception of any schedules, submittals, or other requirements, if any, that must be provided or performed before issuance of the Notice to Proceed. (C) Rate of Progress. Contractor and its Subcontractors must, at all times, provide workers, materials, and equipment sufficient to maintain the rate of progress necessary to ensure full completion of the Work within the Contract Time. If City determines that Contractor is failing to prosecute the Work at a sufficient rate of progress, City may, in its sole discretion, direct Contractor to provide additional workers, materials, or equipment, or to work additional hours or days without additional cost to City, in order to achieve a rate of progress satisfactory to City. If Contractor fails to comply with City’s directive in this regard, City may, at Contractor’s expense, separately contract for additional workers, materials, or equipment or use City’s own forces to achieve the necessary rate of progress. Alternatively, City may terminate the Contract based on Contractor’s default. 5.2 Schedule Requirements. Contractor must prepare all schedules using standard, commercial scheduling software acceptable to the Engineer, and must provide the schedules in electronic and paper form as requested by the Engineer. In addition to the general scheduling requirements set forth below, Contractor must also comply with any scheduling requirements included in the Special Conditions or in the Technical Specifications. (A) Baseline (As-Planned) Schedule. Within ten calendar days following City’s issuance of the Notice to Proceed (or as otherwise specified in the Notice to Proceed), Contractor must submit to City for review and acceptance a baseline (as-planned) schedule using critical path methodology showing in detail how Contractor plans to perform and fully complete the Work within the Contract Time, including labor, equipment, materials and fabricated items. The baseline schedule must show the order of the major items of Work and the dates of start and completion of each item, including when the materials and equipment will be procured. The schedule must also include the work of all trades, reflecting anticipated labor or crew hours and equipment loading for the construction activities, and must be sufficiently comprehensive and detailed to enable progress to be monitored on a day-by-day basis. For each activity, the baseline schedule must be dated, provided in the format specified in the Contract Documents or as required by City, and must include, at a minimum, a description of the activity, the start and completion dates of the activity, and the duration of the activity. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 43 (1) Specialized Materials Ordering. Within five calendar days following issuance of the Notice to Proceed, Contractor must order any specialized material or equipment for the Work that is not readily available from material suppliers. Contractor must also retain documentation of the purchase orders date(s). (B) City’s Review of Schedules. City will review and may note exceptions to the baseline schedule, and to the progress schedules submitted as required below, to assure completion of the Work within the Contract Time. Contractor is solely responsible for resolving any exceptions noted in a schedule and, within seven days, must correct the schedule to address the exceptions. City’s review or acceptance of Contractor’s schedules will not operate to waive or limit Contractor’s duty to complete the Project within the Contract Time, nor to waive or limit City’s right to assess liquidated damages for Contractor’s unexcused failure to do so. (C) Progress Schedules. After City accepts the final baseline schedule with no exceptions, Contractor must submit an updated progress schedule and three-week look- ahead schedule, in the format specified by City, for review and acceptance with each application for a progress payment, or when otherwise specified by City, until completion of the Work. The updated progress schedule must: show how the actual progress of the Work as constructed to date compares to the baseline schedule; reflect any proposed changes in the construction schedule or method of operations, including to achieve Project milestones within the Contract Time; and identify any actual or potential impacts to the critical path. Contractor must also submit periodic reports to City of any changes in the projected material or equipment delivery dates for the Project. (1) Float. The progress schedule must show early and late completion dates for each task. The number of days between those dates will be designated as the “float.” Any float belongs to the Project and may be allocated by the Engineer to best serve timely completion of the Project. (2) Failure to Submit Schedule. Reliable, up-to-date schedules are essential to efficient and cost-effective administration of the Project and timely completion. If Contractor fails to submit a schedule within the time periods specified in this Section, or submits a schedule to which City has noted exceptions that are not corrected, City may withhold up to ten percent from payment(s) otherwise due to Contractor until the exceptions are resolved, the schedule is corrected and resubmitted, and City has accepted the schedule. In addition, Contractor’s failure to comply with the schedule requirements in this Section 5.2 will be deemed a material default and a waiver of any claims for Excusable Delay or loss of productivity arising during any period when Contractor is out of compliance, subject only to the limits of Public Contract Code § 7102. (D) Recovery Schedule. If City determines that the Work is more than one week behind schedule, within seven days following written notice of such determination, Contractor must submit a recovery schedule, showing how Contractor intends to perform and complete the Work within the Contract Time, based on actual progress to date. (E) Effect of Acceptance. Contractor and its Subcontractors must perform the Work in accordance with the most current City-accepted schedule unless otherwise directed by City. City’s acceptance of a schedule does not operate to extend the time for completion of the Work or any component of the Work, and will not affect City’s right to assess liquidated damages for Contractor’s unexcused delay in completing the Work within the Contract Time. (F) Posting. Contractor must at all times prominently post a copy of the most current City-accepted progress or recovery schedule in its on-site office. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 44 (G) Reservation of Rights. City reserves the right to direct the sequence in which the Work must be performed or to make changes in the sequence of the Work in order to facilitate the performance of work by City or others, or to facilitate City’s use of its property. The Contract Time or Contract Price may be adjusted to the extent such changes in sequence actually increase or decrease Contractor’s time or cost to perform the Work. (H) Authorized Working Days and Times. Contractor is limited to working Monday through Friday, excluding holidays, during City’s normal business hours, except as provided in the Special Conditions or as authorized in writing by City. City reserves the right to charge Contractor for additional costs incurred by City due to Work performed on days or during hours not expressly authorized in the Contract Documents, including reimbursement of costs incurred for inspection, testing, and construction management services. 5.3 Delay and Extensions of Contract Time. (A) Notice of Delay. If Contractor becomes aware of any actual or potential delay affecting the critical path, Contractor must promptly notify the Engineer in writing, regardless of the nature or cause of the delay, so that City has a reasonable opportunity to mitigate or avoid the delay. (B) Excusable Delay. The Contract Time may be extended if Contractor encounters “Excusable Delay,” which is an unavoidable delay in completing the Work within the Contract Time due to causes completely beyond Contractor’s control, and which Contractor could not have avoided or mitigated through reasonable care, planning, foresight, and diligence, provided that Contractor is otherwise fully performing its obligations under the Contract Documents. Grounds for Excusable Delay may include fire, natural disasters including earthquake or unusually severe weather, acts of terror or vandalism, epidemic, unforeseeable adverse government actions, unforeseeable actions of third parties, encountering unforeseeable hazardous materials, unforeseeable site conditions, or suspension for convenience under Article 13. The Contract Time will not be extended based on circumstances which will not unavoidably delay completing the Work within the Contract Time based on critical path analysis. (C) Weather Delays. A “Weather Delay Day” is a Working Day during which Contractor and its forces, including Subcontractors, are unable to perform more than 40% of the critical path Work scheduled for that day due to adverse weather conditions which impair the ability to safely or effectively perform the scheduled critical path Work that day. Adverse weather conditions may include rain, saturated soil, and Project site clean-up required due to adverse weather. Determination of what constitutes critical path Work scheduled for that day will be based on the most current, City-approved schedule. Contractor will be entitled to a non-compensable extension of the Contract Time for each Weather Delay Day in excess of the normal Weather Delay Days within a given month as determined by reliable records, including monthly rainfall averages, for the preceding ten years (or as otherwise specified in the Special Conditions or Specifications). (1) Based on historic records for the Project location from the Western Regional Climate Center, Contractor’s schedule should assume the following number of normal Weather Delay Days and precipitation for each month: Month # Normal Weather Precipitation Delay Days January 6 2.86 Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 45 February 6 2.66 March 6 2.29 April 3 1.20 May 1 0.44 June 0 0.10 July 0 0.02 August 0 0.07 September 1 0.19 October 2 0.76 November 4 1.51 December 5 2.43 Total 34 14.53 (2) Contractor must fully comply with the applicable procedures in Articles 5 and 6 of the General Conditions regarding requests to modify the Contract Time. (3) Contractor will not be entitled to an extension of time for a Weather Delay Day to the extent Contractor is responsible for concurrent delay on that day. (4) Contractor must take reasonable steps to mitigate the consequences of Weather Delay Days, including prudent workforce management and protecting the Work, Project Site, materials, and equipment. (D) Non-Excusable Delay. Delay which Contractor could have avoided or mitigated through reasonable care, planning, foresight and diligence is “Non-Excusable Delay.” Contractor is not entitled to an extension of Contract Time or any compensation for Non- Excusable Delay, or for Excusable Delay that is concurrent with Non-Excusable Delay. Non-Excusable Delay includes delay caused by: (1) weather conditions which are normal for the location of the Project, as determined by reliable records, including monthly rainfall averages, for the preceding ten years; (2) Contractor’s failure to order equipment and materials sufficiently in advance of the time needed for completion of the Work within the Contract Time; (3) Contractor’s failure to provide adequate notification to utility companies or agencies for connections or services necessary for completion of the Work within the Contract Time; (4) foreseeable conditions which Contractor could have ascertained from reasonably diligent inspection of the Project site or review of the Contract Documents or other information provided or available to Contractor; (5) Contractor’s failure, refusal, or financial inability to perform the Work within the Contract Time, including insufficient funds to pay its Subcontractors or suppliers; (6) performance or non-performance by Contractor’s Subcontractors or suppliers; (7) the time required to respond to excessive RFIs (see Section 2.5(G)); Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 46 (8) delayed submission of required submittals, or the time required for correction and resubmission of defective submittals; (9) time required for repair of, re-testing, or re-inspection of defective Work; (10) enforcement of Laws by City, or outside agencies with jurisdiction over the Work; or (11) City’s exercise or enforcement of any of its rights or Contractor’s duties pursuant to the Contract Documents, including correction of defective Work, extra inspections or testing due to non-compliance with Contract requirements, safety compliance, environmental compliance, or rejection and return of defective or deficient submittals. (E) Compensable Delay. Pursuant to Public Contract Code § 7102, in addition to entitlement to an extension of Contract Time, Contractor is entitled to compensation for costs incurred due to delay caused solely by City, when that delay is unreasonable under the circumstances involved and not within the contemplation of the parties (“Compensable Delay”). Contractor is not entitled to an extension of Contract Time or recovery of costs for Compensable Delay that is concurrent with Non-Excusable Delay. Delay due to causes that are beyond the control of either City or Contractor, including Weather Delay Days, discovery of Historic or Archeological Items pursuant to Section 7.18, or the actions or inactions of third parties or other agencies, is not Compensable Delay, and will only entitle Contractor to an extension of time commensurate with the time lost due to such delay. (F) Recoverable Costs. Contractor is not entitled to compensation for Excusable Delay unless it is Compensable Delay, as defined above. Contractor is entitled to recover only the actual, direct, reasonable, and substantiated costs (“Recoverable Costs”) for each working day that the Compensable Delay prevents Contractor from proceeding with more than 50% of the critical path Work scheduled for that day, based on the most recent progress schedule accepted by City. Recoverable Costs will not include home office overhead or lost profit. (G) Request for Extension of Contract Time or Recoverable Costs. A request for an extension of Contract Time or any associated Recoverable Costs must be submitted in writing to City within ten calendar days of the date the delay is first encountered, even if the duration of the delay is not yet known at that time, or any entitlement to the Contract Time extension or to the Recoverable Costs will be deemed waived. In addition to complying with the requirements of this Article 5, the request must be submitted in compliance with the Change Order request procedures in Article 6 below. Strict compliance with these requirements is necessary to ensure that any delay or consequences of delay may be mitigated as soon as possible, and to facilitate cost- efficient administration of the Project and timely performance of the Work. Any request for an extension of Contract Time or Recoverable Costs that does not strictly comply with all of the requirements of Article 5 and Article 6 will be deemed waived. (1) Required Contents. The request must include a detailed description of the cause(s) of the delay and must also describe the measures that Contractor has taken to mitigate the delay and/or its effects, including efforts to mitigate the cost impact of the delay, such as by workforce management or by a change in sequencing. If the delay is still ongoing at the time the request is submitted, the request should also include Contractor’s plan for continued mitigation of the delay or its effects. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 47 (2) Delay Days and Costs. The request must specify the number of days of Excusable Delay claimed or provide a realistic estimate if the duration of the delay is not yet known. If Contractor believes it is entitled to Recoverable Costs for Compensable Delay, the request must specify the amount and basis for the Recoverable Costs that are claimed or provide a realistic estimate if the amount is not yet known. Any estimate of delay duration or cost must be updated in writing and submitted with all required supporting documentation as soon as the actual time and cost is known. The maximum extension of Contract Time will be the number of days, if any, by which an Excusable Delay or a Compensable Delay exceeds any concurrent Non-Excusable Delay. Contractor is entitled to an extension of Contract Time, or compensation for Recoverable Costs, only if, and only to the extent that, such delay will unavoidably delay Final Completion. (3) Supporting Documentation. The request must also include any and all supporting documentation necessary to evidence the delay and its actual impacts, including scheduling and cost impacts with a time impact analysis using critical path methodology and demonstrating the unavoidable delay to Final Completion. The time impact analysis must be submitted in a form or format acceptable to City. (4) Burden of Proof. Contractor has the burden of proving that: the delay was an Excusable or Compensable Delay, as defined above; Contractor has fully complied with its scheduling obligations in Section 5.2, Schedule Requirements; Contractor has made reasonable efforts to mitigate the delay and its schedule and cost impacts; the delay will unavoidably result in delaying Final Completion; and any Recoverable Costs claimed by Contractor were actually incurred and were reasonable under the circumstances. (5) Legal Compliance. Nothing in this Section 5.3 is intended to require the waiver, alteration, or limitation of the applicability of Public Contract Code § 7102. (6) No Waiver. Any grant of an extension of Contract Time, or compensation for Recoverable Costs due to Compensable Delay, will not operate as a waiver of City’s right to assess liquidated damages for Non-Excusable Delay. (7) Dispute Resolution. In the event of a dispute over entitlement to an extension of Contract Time or compensation for Recoverable Costs, Contractor may not stop Work pending resolution of the dispute, but must continue to comply with its duty to diligently prosecute the performance and timely completion of the Work. Contractor’s sole recourse for an unresolved dispute based on City’s rejection of a Change Order request for an extension of Contract Time or compensation for Recoverable Costs is to comply with the dispute resolution provisions set forth in Article 12 below. 5.4 Liquidated Damages. It is expressly understood that if Final Completion is not achieved within the Contract Time, City will suffer damages from the delay that are difficult to determine and accurately specify. Pursuant to Public Contract Code § 7203, if Contractor fails to achieve Final Completion within the Contract Time, City will charge Contractor in the amount specified in the Contract for each day that Final Completion is delayed beyond the Contract Time, as liquidated damages and not as a penalty. Any waiver of accrued liquidated damages, in whole or in part, is subject to approval of the City Council or its authorized delegee. (A) Liquidated Damages. Liquidated damages will not be assessed for any Excusable or Compensable Delay, as set forth above. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 48 (B) Milestones. Liquidated damages may also be separately assessed for failure to meet milestones specified elsewhere in the Contract Documents. (C) Setoff. City is entitled to deduct the amount of liquidated damages assessed against any payments otherwise due to Contractor, including progress payments, Final Payment, or unreleased retention. If there are insufficient Contract funds remaining to cover the full amount of liquidated damages assessed, City is entitled to recover the balance from Contractor or its performance bond surety. (D) Occupancy or Use. Occupancy or use of the Project in whole or in part prior to Final Completion does not constitute City’s acceptance of the Project and will not operate as a waiver of City’s right to assess liquidated damages for Contractor’s Non-Excusable Delay in achieving Final Completion. (E) Other Remedies. City’s right to liquidated damages under this Section applies only to damages arising from Contractor’s Non-Excusable Delay or failure to complete the Work within the Contract Time. City retains its right to pursue all other remedies under the Contract for other types of damage, including damage to property or persons, costs or diminution in value from defective materials or workmanship, costs to repair or complete the Work, or other liability caused by Contractor. Article 6 - Contract Modification 6.1 Contract Modification. Subject to the limited exception set forth in subsection (D) below, any change in the Work or the Contract Documents, including the Contract Price or Contract Time, will not be a valid and binding change to the Contract unless it is formalized in a Change Order, including a “no-cost” Change Order or a unilateral Change Order. Changes in the Work pursuant to this Article 6 will not operate to release, limit, or abridge Contractor’s warranty obligations pursuant to Article 11 or any obligations of Contractor’s bond sureties. (A) City-Directed Changes. City may direct changes in the scope or sequence of Work or the requirements of the Contract Documents, without invalidating the Contract. Such changes may include Extra Work as set forth in subsection (C) below, or deletion or modification of portions of the Work. Contractor must promptly comply with City-directed changes in the Work in accordance with the original Contract Documents, even if Contractor and City have not yet reached agreement as to adjustments to the Contract Price or Contract Time for the change in the Work or for the Extra Work. Contractor is not entitled to extra compensation for cost savings resulting from “value engineering” pursuant to Public Contract Code § 7101, except to the extent authorized in advance by City in writing, and subject to any applicable procedural requirements for submitting a proposal for value engineering cost savings. (B) Disputes. In the event of a dispute over entitlement to or the amount of a change in Contract Time or a change in Contract Price related to a City-directed change in the Work, Contractor must perform the Work as directed and may not delay its Work or cease Work pending resolution of the dispute, but must continue to comply with its duty to diligently prosecute the performance and timely completion of the Work, including the Work in dispute. Likewise, in the event that City and Contractor dispute whether a portion or portions of the Work are already required by the Contract Documents or constitute Extra Work, or otherwise dispute the interpretation of any portion(s) of the Contract Documents, Contractor must perform the Work as directed and may not delay its Work or cease Work pending resolution of the dispute, but must continue to comply with its duty to diligently prosecute the performance and timely completion of the Work, including the Work in dispute, as directed by City. If Contractor refuses to perform the Work in dispute, Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 49 City may, acting in its sole discretion, elect to delete the Work from the Contract and reduce the Contract Price accordingly, and self-perform the Work or direct that the Work be performed by others. Alternatively, City may elect to terminate the Contract for convenience or for cause. Contractor’s sole recourse for an unresolved dispute related to changes in the Work or performance of any Extra Work is to comply with the dispute resolution provisions set forth in Article 12, below. (C) Extra Work. City may direct Contractor to perform Extra Work related to the Project. Contractor must promptly perform any Extra Work as directed or authorized by City in accordance with the original Contract Documents, even if Contractor and City have not yet reached agreement on adjustments to the Contract Price or Contract Time for such Extra Work. If Contractor believes it is necessary to perform Extra Work due to changed conditions, Contractor must promptly notify the Engineer in writing, specifically identifying the Extra Work and the reason(s) the Contractor believes it is Extra Work. This notification requirement does not constitute a Change Order request pursuant to Section 6.2, below. Contractor must maintain detailed daily records that itemize the cost of each element of Extra Work, and sufficiently distinguish the direct cost of the Extra Work from the cost of other Work performed. For each day that Contractor performs Extra Work, or Work that Contractor contends is Extra Work, Contractor must submit no later than the following Working Day, a daily report of the Extra Work performed that day and the related costs, together with copies of certified payroll, invoices, and other documentation substantiating the costs (“Extra Work Report”). The Engineer will make any adjustments to Contractor’s Extra Work Report(s) based on the Engineer’s records of the Work. When an Extra Work Report(s) is agreed on and signed by both City and Contractor, the Extra Work Report(s) will become the basis for payment under a duly authorized and signed Change Order. Failure to submit the required documentation by close of business on the next Working Day is deemed a full and complete waiver for any change in the Contract Price or Contract Time for any Extra Work performed that day. (D) Minor Changes and RFIs. Minor field changes, including RFI replies from City, that do not affect the Contract Price or Contract Time and that are approved by the Engineer acting within his or her scope of authority, do not require a Change Order. By executing an RFI reply from City, Contractor agrees that it will perform the Work as clarified therein, with no change to the Contract Price or Contract Time. (E) Remedy for Non-Compliance. Contractor’s failure to promptly comply with a City-directed change is deemed a material breach of the Contract, and in addition to all other remedies available to it, City may, at its sole discretion, hire another contractor or use its own forces to complete the disputed Work at Contractor’s sole expense, and may deduct the cost from the Contract Price. 6.2 Contractor Change Order Requests. Contractor must submit a request or proposal for a change in the Work, compensation for Extra Work, or a change in the Contract Price or Contract Time as a written Change Order request or proposal. (A) Time for Submission. Any request for a change in the Contract Price or the Contract Time must be submitted in writing to the Engineer within ten calendar days of the date that Contractor first encounters the circumstances, information or conditions giving rise to the Change Order request, even if the total amount of the requested change in the Contract Price or impact on the Contract Time is not yet known at that time. If City requests that Contractor propose the terms of a Change Order, unless otherwise specified in City’s request, Contractor must provide the Engineer with a written proposal for the change in the Contract Price or Contract Time within five working days of receiving City’s request, in a form satisfactory to the Engineer. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 50 (B) Required Contents. Any Change Order request or proposal submitted by Contractor must include a complete breakdown of actual or estimated costs and credits, and must itemize labor, materials, equipment, taxes, insurance, subcontract amounts, and, if applicable, Extra Work Reports. Any estimated cost must be updated in writing as soon as the actual amount is known. (C) Required Documentation. All claimed costs must be fully documented, and any related request for an extension of time or delay-related costs must be included at that time and in compliance with the requirements of Article 5 of the General Conditions. Upon request, Contractor must permit City to inspect its original and unaltered bidding records, subcontract agreements, subcontract change orders, purchase orders, invoices, or receipts associated with the claimed costs. (D) Required Form. Contractor must use City’s form(s) for submitting all Change Order requests or proposals, unless otherwise specified by City. (E) Certification. All Change Order requests must be signed by Contractor and must include the following certification: “The undersigned Contractor certifies under penalty of perjury that its statements and representations in this Change Order request are true and correct. Contractor warrants that this Change Order request is comprehensive and complete as to the Work or changes referenced herein, and agrees that any known or foreseeable costs, expenses, or time extension requests not included herein, are deemed waived.” 6.3 Adjustments to Contract Price. The amount of any increase or decrease in the Contract Price will be determined based on one of the following methods listed below, in the order listed with unit pricing taking precedence over the other methods. Markup applies only to City-authorized time and material Work, and does not apply to any other payments to Contractor. For Work items or components that are deleted in their entirety, Contractor will only be entitled to compensation for those direct, actual, and documented costs (including restocking fees), reasonably incurred before Contractor was notified of the City’s intent to delete the Work, with no markup for overhead, profit, or other indirect costs. (A) Unit Pricing. Amounts previously provided by Contractor in the form of unit prices, either in a bid schedule or in a post-award schedule of values pursuant to Section 8.1, Schedule of Values, will apply to determine the price for the affected Work, to the extent applicable unit prices have been provided for that type of Work. No additional markup for overhead, profit, or other indirect costs will be added to the calculation. (B) Lump Sum. A mutually agreed upon, all-inclusive lump sum price for the affected Work with no additional markup for overhead, profit, or other indirect costs. (C) Time and Materials. On a time and materials basis, if and only to the extent compensation on a time and materials basis is expressly authorized by City in advance of Contractor’s performance of the Work and subject to any not-to-exceed limit. Time and materials compensation for increased costs or Extra Work (but not decreased costs or deleted Work), will include allowed markup for overhead, profit, and other indirect costs, and which may include a not-to-exceed limit, calculated as the total of the following sums, the cumulative total of which may not exceed the maximum markup rate of 15%: (1) All direct labor costs provided by the Contractor, excluding superintendence, project management, or administrative costs, plus 15% markup; Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 51 (2) All direct material costs provided by the Contractor, including sales tax, plus 15% markup; (3) All direct plant and equipment rental costs provided by the Contractor, plus 15% markup; (4) All direct additional subcontract costs plus 10% markup for Work performed by Subcontractors; and (5) Increased bond or insurance premium costs computed at 1.5% of total of the previous four sums. 6.4 Unilateral Change Order. If the parties dispute the terms of a proposed Change Order, including disputes over the amount of compensation or extension of time that Contractor has requested, the value of deleted or changed Work, what constitutes Extra Work, or quantities used, City may elect to issue a unilateral Change Order, directing performance of the Work, and authorizing a change in the Contract Price or Contract Time for the adjustment to compensation or time that the City believes is merited. Contractor’s sole recourse to dispute the terms of a unilateral Change Order is to submit a timely Claim pursuant to Article 12, below. 6.5 Non-Compliance Deemed Waiver. Contractor waives its entitlement to any increase in the Contract Price or Contract Time if Contractor fails to fully comply with the provisions of this Article. Contractor will not be paid for unauthorized Extra Work. Article 7 - General Construction Provisions 7.1 Permits, Fees, Business License, and Taxes. (A) Permits, Fees, and City Business License. Contractor must obtain and pay for all permits, fees, or licenses required to perform the Work, including a City business license. Contractor must cooperate with and provide notifications to all government agencies with jurisdiction over the Project, as may be required. Contractor must provide City with copies of all records of permits and permit applications, payment of required fees, and any licenses required for the Work. (B) Taxes. Contractor must pay for all taxes on labor, material and equipment, except Federal Excise Tax to the extent that City is exempt from Federal Excise Tax. 7.2 Temporary Facilities. Contractor must provide, at Contractor’s sole expense, any and all temporary facilities for the Project, including an onsite staging area for materials and equipment, a field office, sanitary facilities, utilities, storage, scaffolds, barricades, walkways, and any other temporary structure required to safely perform the Work along with any incidental utility services. The location of all temporary facilities must be approved by the City prior to installation. Temporary facilities must be safe and adequate for the intended use and installed and maintained in accordance with Laws and the Contract Documents. Contractor must fence and screen the Project site and, if applicable, any separate Worksites, including the staging area, and its operation must minimize inconvenience to neighboring properties. Additional provisions pertaining to temporary facilities may be included in the Specifications or Special Conditions. (A) Utilities. Contractor must install and maintain the power, water, sewer and all other utilities required for the Project site, including the piping, wiring, internet and wifi connections, and any related equipment necessary to maintain the temporary facilities. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 52 (B) Removal and Repair. Contractor must promptly remove all such temporary facilities when they are no longer needed or upon completion of the Work, whichever comes first. Contractor must promptly repair any damage to City’s property or to other property caused by the installation, use, or removal of the temporary facilities, and must promptly restore the property to its original or intended condition. 7.3 Noninterference and Site Management. Contractor must avoid interfering with City’s use of its property at or adjacent to the Project site, including use of roadways, entrances, parking areas, walkways, and structures. Contractor must also minimize disruption of access to private property in the Project vicinity. Contractor must coordinate with affected property owners, tenants, and businesses, and maintain some vehicle and pedestrian access to their residences or properties at all times. Temporary access ramps, fencing or other measures must be provided as needed. Before blocking access to a private driveway or parking lot, Contractor must provide effective notice to the affected parties at least 48 hours in advance of the pending closure and allow them to remove vehicles. Private driveways, residences and parking lots must have access to a roadway during non-Work hours. (A) Offsite Acquisition. Unless otherwise provided by City, Contractor must acquire, use and dispose of, at its sole expense, any additional Worksites, licenses, easements, and temporary facilities necessary to access and perform the Work. (B) Offsite Staging Area and Field Office. If additional space beyond the Project site is needed, such as for the staging area or the field office, Contractor may need to make arrangements with the nearby property owner(s) to secure the space. Before using or occupying any property owned by a third party, Contractor must provide City with a copy of the necessary license agreement, easement, or other written authorization from the property owner, together with a written release from the property owner holding City harmless from any related liability, in a form acceptable to the City Attorney. (C) Traffic Management. Contractor must provide traffic management and traffic controls as specified in the Contract Documents, as required by Laws, and as otherwise required to ensure the public and worker safety, and to avoid interference with public or private operations or the normal flow of vehicular, bicycle, or pedestrian traffic. 7.4 Signs. No signs may be displayed on or about City’s property, except signage which is required by Laws or by the Contract Documents, without City’s prior written approval as to size, design, and location. 7.5 Project Site and Nearby Property Protections. (A) General. Contractor is responsible at all times, on a 24-hour basis and at its sole cost, for protecting the Work, the Project site, and the materials and equipment to be incorporated into the Work, until the City has accepted the Project, excluding any exceptions to acceptance, if any. Except as specifically authorized by City, Contractor must confine its operations to the area of the Project site indicated in the Plans and Specifications. Contractor is liable for any damage caused by Contractor or its Subcontractors to the Work, City’s property, the property of adjacent or nearby property owners and the work or personal property of other contractors working for City, including damage related to Contractor’s failure to adequately secure the Work or any Worksite. (1) Subject to City’s approval, Contractor will provide and install safeguards to protect the Work; any Worksite, including the Project site; City’s real or personal property and the real or personal property of adjacent or nearby property owners, including plant and tree protections. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 53 (2) City wastewater systems may not be interrupted. If the Work disrupts existing sewer facilities, Contractor must immediately notify City and establish a plan, subject to City’s approval, to convey the sewage in closed conduits back into the sanitary sewer system. Sewage must not be permitted to flow in trenches or be covered by backfill. (3) Contractor must remove with due care, and store at City’s request, any objects or material from the Project site that City will salvage or reuse at another location. (4) If directed by Engineer, Contractor must promptly repair or replace any property damage, as specified by the Engineer. However, acting in its sole discretion, City may elect to have the property damage remedied otherwise, and may deduct the cost to repair or replace the damaged property from payment otherwise due to Contractor. (5) Contractor will not permit any structure or infrastructure to be loaded in a manner that will damage or endanger the integrity of the structure or infrastructure. (B) Securing Project Site. After completion of Work each day, Contractor must secure the Project site and, to the extent feasible, make the area reasonably accessible to the public unless City approves otherwise. All excess materials and equipment not protected by approved traffic control devices must be relocated to the staging area or demobilized. Trench spoils must be hauled off the Project site daily and open excavations must be protected with steel plates. Contractor and Subcontractor personnel may not occupy or use the Project site for any purpose during non-Work hours, except as may be provided in the Contract Documents or pursuant to prior written authorization from City. (C) Unforeseen Conditions. If Contractor encounters facilities, utilities, or other unknown conditions not shown on or reasonably inferable from the Plans or apparent from inspection of the Project site, Contractor must immediately notify the City and promptly submit a Request for Information to obtain further directions from the Engineer. Contractor must avoid taking any action which could cause damage to the facilities or utilities pending further direction from the Engineer. The Engineer’s written response will be final and binding on Contractor. If the Engineer’s subsequent direction to Contractor affects Contractor’s cost or time to perform the Work, Contractor may submit a Change Order request as set forth in Article 6 above. (D) Support; Adjacent Properties. Contractor must provide, install, and maintain all shoring, bracing, and underpinning necessary to provide support to City’s property and adjacent properties and improvements thereon. Contractor must provide notifications to adjacent property owners as may be required by Laws. See also, Section 7.15, Trenching of Five Feet or More. (E) Notification of Property Damage. Contractor must immediately notify the City of damage to any real or personal property resulting from Work on the Project. Contractor must immediately provide a written report to City of any such property damage in excess of $500 (based on estimated cost to repair or replace) within 24 hours of the occurrence. The written report must include: (1) the location and nature of the damage, and the owner of the property, if known; (2) the name and address of each employee of Contractor or any Subcontractor involved in the damage; (3) a detailed description of the incident, including precise location, time, and names and contact information for known witnesses; and (4) a police or first responder report, if applicable. If Contractor is required to file an accident report with another government agency, Contractor will provide a copy of the report to City. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 54 7.6 Materials and Equipment. (A) General. Unless otherwise specified, all materials and equipment required for the Work must be new, free from defects, and of the best grade for the intended purpose, and furnished in sufficient quantities to ensure the proper and expeditious performance of the Work. Contractor must employ measures to preserve the specified quality and fitness of the materials and equipment. Unless otherwise specified, all materials and equipment required for the Work are deemed to include all components required for complete installation and intended operation and must be installed in accordance with the manufacturer’s recommendations or instructions. Contractor is responsible for all shipping, handling, and storage costs associated with the materials and equipment required for the Work. Contractor is responsible for providing security and protecting the Work and all of the required materials, supplies, tools and equipment at Contractor’s sole cost until City has formally accepted the Project as set forth in Section 11.1, Final Completion. Contractor will not assign, sell, mortgage, or hypothecate any materials or equipment for the Project, or remove any materials or equipment that have been installed or delivered. (B) City-Provided. If the Work includes installation of materials or equipment to be provided by City, Contractor is solely responsible for the proper examination, handling, storage, and installation in accordance with the Contract Documents. Contractor must notify City of any defects discovered in City-provided materials or equipment, sufficiently in advance of scheduled use or installation to afford adequate time to procure replacement materials or equipment as needed. Contractor is solely responsible for any loss of or damage to such items which occurs while the items are in Contractor’s custody and control, the cost of which may be offset from the Contract Price and deducted from any payment(s) due to Contractor. (C) Intellectual Property Rights. Contractor must, at its sole expense, obtain any authorization or license required for use of patented or copyright-protected materials, equipment, devices or processes that are incorporated into the Work. Contractor’s indemnity obligations in Article 4 apply to any claimed violation of intellectual property rights in violation of this provision. 7.7 Substitutions. (A) “Or Equal.” Any Specification designating a material, product, or thing (collectively, “item”) or service by specific brand or trade name, followed by the words “or equal,” is intended only to indicate the quality and type of item or service desired, and Contractor may request use of any equal item or service. Unless otherwise stated in the Specifications, any reference to a specific brand or trade name for an item that is used solely for the purpose of describing the type of item desired, will be deemed to be followed by the words “or equal.” A substitution will only be approved if it is a true “equal” item in every aspect of design, function, and quality, as determined by City, including dimensions, weight, maintenance requirements, durability, fit with other elements, and schedule impacts. (B) Request for Substitution. A post-award request for substitution of an item or service must be submitted in writing to the Engineer for approval in advance, within the applicable time period provided in the Contract Documents. If no time period is specified, the substitution request may be submitted any time within 35 days after the date of award of the Contract, or sufficiently in advance of the time needed to avoid delay of the Work, whichever is earlier. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 55 (C) Substantiation. Any available data substantiating the proposed substitute as an equal item or service must be submitted with the written request for substitution. Contractor’s failure to timely provide all necessary substantiation, including any required test results as soon as they are available, is grounds for rejection of the proposed substitution, without further review. (D) Burden of Proving Equality. Contractor has the burden of proving the equality of the proposed substitution at Contractor’s sole cost. City has sole discretion to determine whether a proposed substitution is equal, and City’s determination is final. (E) Approval or Rejection. If the proposed substitution is approved, Contractor is solely responsible for any additional costs or time associated with the substituted item or service. If the proposed substitution is rejected, Contractor must, without delay, install the item or use the service as specified by City. (F) Contractor’s Obligations. City’s approval of a proposed substitution will not relieve Contractor from any of its obligations under the Contract Documents. In the event Contractor makes an unauthorized substitution, Contractor will be solely responsible for all resulting cost impacts, including the cost of removal and replacement and the impact to other design elements. 7.8 Testing and Inspection. (A) General. All materials, equipment, and workmanship used in the Work are subject to inspection and testing by City at all times and locations during construction and/or fabrication and at any Worksite, including at shops and yards as well as at the Project site. All manufacturers’ application or installation instructions must be provided to the Inspector at least ten days prior to the first such application or installation. Contractor must, at all times, make the Work available for testing or inspection. Neither City’s inspection or testing of Work, nor its failure to do so, operate to waive or limit Contractor’s duty to complete the Work in accordance with the Contract Documents. (B) Scheduling and Notification. Contractor must cooperate with City in coordinating the inspections and testing. Contractor must submit samples of materials, at Contractor’s expense, and schedule all tests required by the Contract Documents in time to avoid any delay to the progress of the Work. Contractor must notify the Engineer no later than noon of the Working Day before any inspection or testing and must provide timely notice to the other necessary parties as specified in the Contract Documents. If Contractor schedules an inspection or test beyond regular Work hours, or on a Saturday, Sunday, or recognized City holiday, Contractor must notify the Engineer at least two Working Days in advance for approval. If approved, Contractor must reimburse City for the cost of the overtime inspection or testing.

If Contractor encounters materials on the Project site that Contractor reasonably believes to be asbestos or other Hazardous Materials, and the asbestos or other Hazardous Materials have not been rendered harmless, Contractor may continue Work in unaffected areas reasonably believed to be safe, but must immediately cease work on the area affected and report the condition to City. No asbestos, asbestos-containing products or other Hazardous Materials may be used in performance of the Work. 10.3 Material Safety. Contractor is solely responsible for complying with § 5194 of Title 8 of the California Code of Regulations, including by providing information to Contractor’s employees about any hazardous chemicals to which they may be exposed in the course of the Work. A hazard communication program and other forms of warning and training about such exposure must be used. Contractor must also maintain Safety Data Sheets (“SDS”) at the Project site, as required by Laws, for materials or substances used or consumed in the performance of the Work. The SDS will be accessible and available to Contractor’s employees, Subcontractors, and City. (A) Contractor Obligations. Contractor is solely responsible for the proper delivery, handling, use, storage, removal, and disposal of all materials brought to the Project site and/or used in the performance of the Work. Contractor must notify the Engineer if a specified product or material cannot be used safely. (B) Labeling. Contractor must ensure proper labeling on any material brought onto the Project site so that any persons working with or in the vicinity of the material may be informed as to the identity of the material, any potential hazards, and requirements for proper handling, protections, and disposal. 10.4 Hazardous Condition. Contractor is solely responsible for determining whether a hazardous condition exists or is created during the course of the Work, involving a risk of bodily harm to any person or risk of damage to any property. If a hazardous condition Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 67 exists or is created, Contractor must take all precautions necessary to address the condition and ensure that the Work progresses safely under the circumstances. Hazardous conditions may result from, but are not limited to, use of specified materials or equipment, the Work location, the Project site condition, the method of construction, or the way any Work must be performed. 10.5 Emergencies. In an emergency affecting the safety or protection of persons, Work, or property at or adjacent to any Worksite, Contractor must take reasonable and prompt actions to prevent damage, injury, or loss, without prior authorization from the City if, under the circumstances, there is inadequate time to seek prior authorization from the City. Article 11 - Completion and Warranty Provisions 11.1 Final Completion. (A) Final Inspection and Punch List. When the Work required by this Contract is fully performed, Contractor must provide written notification to City requesting final inspection. The Engineer will schedule the date and time for final inspection, which must include Contractor’s primary representative for this Project and its superintendent. Based on that inspection, City will prepare a punch list of any items that are incomplete, missing, defective, incorrectly installed, or otherwise not compliant with the Contract Documents. The punch list to Contractor will specify the time by which all of the punch list items must be completed or corrected. The punch list may include City’s estimated cost to complete each punch list item if Contractor fails to do so within the specified time. The omission of any non-compliant item from a punch list will not relieve Contractor from fulfilling all requirements of the Contract Documents. Contractor’s failure to complete any punch list item within the time specified in the punch list will not waive or abridge its warranty obligations for any such items that must be completed by the City or by a third party retained by the City due to Contractor’s failure to timely complete any such outstanding item. (B) Requirements for Final Completion. Final Completion will be achieved upon completion or correction of all punch list items, as verified by City’s further inspection, and upon satisfaction of all other Contract requirements, including any commissioning required under the Contract Documents and submission of all final submittals, including instructions and manuals as required under Section 7.10, and complete, final as-built drawings as required under Section 7.11, all to City’s satisfaction. (C) Acceptance. The Project will be considered accepted upon City Council action during a public meeting to accept the Project, unless the Engineer is authorized to accept the Project, in which case the Project will be considered accepted upon the date of the Engineer’s issuance of a written notice of acceptance. In order to avoid delay of Project close out, the City may elect, acting in its sole discretion, to accept the Project as complete subject to exceptions for punch list items that are not completed within the time specified in the punch list. (D) Final Payment and Release of Retention. Final Payment and release of retention, less any sums withheld pursuant to the provisions of the Contract Documents, will not be made sooner than 35 days after recordation of the notice of completion. If Contractor fails to complete all of the punch list items within the specified time, City may withhold up to 150% of City’s estimated cost to complete each of the remaining items from Final Payment and may use the withheld retention to pay for the costs to self- perform the outstanding items or to retain a third party to complete any such outstanding punch list item. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 68 11.2 Warranty. (A) General. Contractor warrants that all materials and equipment will be new unless otherwise specified, of good quality, in conformance with the Contract Documents, and free from defective workmanship and materials. Contractor further warrants that the Work will be free from material defects not intrinsic in the design or materials required in the Contract Documents. Contractor warrants that materials or items incorporated into the Work comply with the requirements and standards in the Contract Documents, including compliance with Laws, and that any Hazardous Materials encountered or used were handled as required by Laws. At City’s request, Contractor must furnish satisfactory evidence of the quality and type of materials and equipment furnished. Contractor’s warranty does not extend to damage caused by normal wear and tear, or improper use or maintenance. (B) Warranty Period. Contractor’s warranty must guarantee its Work for a period of one year from the date of Project acceptance (the “Warranty Period”), except when a longer guarantee is provided by a supplier or manufacturer or is required by the Specifications or Special Conditions. Contractor must obtain from its Subcontractors, suppliers and manufacturers any special or extended warranties required by the Contract Documents. (C) Warranty Documents. As a condition precedent to Final Completion, Contractor must supply City with all warranty and guarantee documents relevant to equipment and materials incorporated into the Work and guaranteed by their suppliers or manufacturers. (D) Subcontractors. The warranty obligations in the Contract Documents apply to Work performed by Contractor and its Subcontractors, and Contractor agrees to be co- guarantor of such Work. (E) Contractor’s Obligations. Upon written notice from City to Contractor of any defect in the Work discovered during the Warranty Period, Contractor or its responsible Subcontractor must promptly correct the defective Work at its own cost. Contractor’s obligation to correct defects discovered during the Warranty Period will continue past the expiration of the Warranty Period as to any defects in Work for which Contractor was notified prior to expiration of the Warranty Period. Work performed during the Warranty Period (“Warranty Work”) will be subject to the warranty provisions in this Section 11.2 for a one-year period that begins upon completion of such Warranty Work to City’s satisfaction. (F) City’s Remedies. If Contractor or its responsible Subcontractor fails to correct defective Work within ten days following notice by City, or sooner if required by the circumstances, City may correct the defects to conform with the Contract Documents at Contractor’s sole expense. Contractor must reimburse City for its costs in accordance with subsection (H), below. (G) Emergency Repairs. In cases of emergency where any delay in correcting defective Work could cause harm, loss or damage, City may immediately correct the defects to conform with the Contract Documents at Contractor’s sole expense. Contractor or its surety must reimburse City for its costs in accordance with subsection (H), below. (H) Reimbursement. Contractor must reimburse City for its costs to repair under subsections (F) or (G), above, within 30 days following City’s submission of a demand for payment pursuant to this provision. If City is required to initiate legal action to compel Contractor’s compliance with this provision, and City is the prevailing party in such action, Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 69 Contractor and its surety are solely responsible for all of City’s attorney’s fees and legal costs expended to enforce Contractor’s warranty obligations herein in addition to any and all costs City incurs to correct the defective Work. 11.3 Use Prior to Final Completion. City reserves the right to occupy or make use of the Project, or any portions of the Project, prior to Final Completion if City has determined that the Project or portion of it is in a condition suitable for the proposed occupation or use, and that it is in its best interest to occupy or make use of the Project, or any portions of it, prior to Final Completion. City will notify Contractor in writing of its intent to occupy or make use of the Project or any portions of the Project, pursuant to this provision. (A) Non-Waiver. Occupation or use of the Project, in whole or in part, prior to Final Completion will not operate as acceptance of the Work or any portion of it, nor will it operate as a waiver of any of City’s rights or Contractor’s duties pursuant to these Contract Documents, and will not affect nor bear on the determination of the time of substantial completion with respect to any statute of repose pertaining to the time for filing an action for construction defect. (B) City’s Responsibility. City will be responsible for the cost of maintenance and repairs due to normal wear and tear with respect to those portions of the Project that are being occupied or used before Final Completion. The Contract Price or the Contract Time may be adjusted pursuant to the applicable provisions of these Contract Documents if, and only to the extent that, any occupation or use under this Section actually adds to Contractor’s cost or time to complete the Work within the Contract Time. 11.4 Substantial Completion. For purposes of determining “substantial completion” with respect to any statute of repose pertaining to the time for filing an action for construction defect, “substantial completion” is deemed to mean the last date that Contractor or any Subcontractor performs Work on the Project prior to City acceptance of the Project, except for warranty work performed under this Article. Article 12 - Dispute Resolution 12.1 Claims. This Article applies to and provides the exclusive procedures for any Claim arising from or related to the Contract or performance of the Work. (A) Definition. “Claim” means a separate demand by Contractor, submitted in writing by registered or certified mail with return receipt requested, for a change in the Contract Time, including a time extension or relief from liquidated damages, or a change in the Contract Price, when the demand has previously been submitted to City in accordance with the requirements of the Contract Documents, and which has been rejected or disputed by City, in whole or in part. A Claim may also include that portion of a unilateral Change Order that is disputed by the Contractor. (B) Limitations. A Claim may only include the portion of a previously rejected demand that remains in dispute between Contractor and City. With the exception of any dispute regarding the amount of money actually paid to Contractor as Final Payment, Contractor is not entitled to submit a Claim demanding a change in the Contract Time or the Contract Price, which has not previously been submitted to City in full compliance with Article 5 and Article 6, and subsequently rejected in whole or in part by City. (C) Scope of Article. This Article is intended to provide the exclusive procedures for submission and resolution of Claims of any amount and applies in addition to the provisions of Public Contract Code § 9204 and § 20104 et seq., which are incorporated by reference herein. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 70 (D) No Work Delay. Notwithstanding the submission of a Claim or any other dispute between the parties related to the Project or the Contract Documents, Contractor must perform the Work and may not delay or cease Work pending resolution of a Claim or other dispute, but must continue to diligently prosecute the performance and timely completion of the Work, including the Work pertaining to the Claim or other dispute. (E) Informal Resolution. Contractor will make a good faith effort to informally resolve a dispute before initiating a Claim, preferably by face-to-face meeting between authorized representatives of Contractor and City. 12.2 Claims Submission.

If, by the time of the Claim submission deadline (below), the precise amount of the requested change in the Contract Price or Contract Time is not yet known, Contractor must provide a good faith estimate, including the basis for that estimate, and must identify the date by which it is anticipated that the Claim will be updated to provide final amounts. (5) Include the following certification, executed by Contractor’s authorized representative: “The undersigned Contractor certifies under penalty of perjury that its statements and representations in this Claim submittal are true and correct. Contractor warrants that this Claim submittal is comprehensive and complete as to the matters in dispute, and agrees that any costs, expenses, or delay not included herein are deemed waived.” (C) Submission Deadlines. (1) A Claim disputing rejection of a request for a change in the Contract Time or Contract Price must be submitted within 15 days following the date that City notified Contractor in writing that a request for a change in the Contract Time or Contract Price, duly submitted in compliance with Article 5 and Article 6, has been rejected in whole or in part. A Claim disputing the terms of a unilateral Change Order must be submitted within 15 days following the date of issuance of the unilateral Change Order. These Claim deadlines apply even if Contractor cannot yet quantify the total amount of any requested change in the Contract Time or Contract Price. If the Contractor cannot quantify those amounts, it must submit an estimate of the amounts claimed pending final determination of the requested remedy by Contractor. (2) With the exception of any dispute regarding the amount of Final Payment, any Claim must be filed on or before the date of Final Payment or will be deemed waived. (3) A Claim disputing the amount of Final Payment must be submitted within 15 days of the effective date of Final Payment, under Section 8.7, Final Payment. (4) Strict compliance with these Claim submission deadlines is necessary to ensure that any dispute may be mitigated as soon as possible, and to facilitate cost-efficient administration of the Project. Any Claim that is not submitted within the specified deadlines will be deemed waived by Contractor. 12.3 City’s Response. City will respond within 45 days of receipt of the Claim with a written statement identifying which portion(s) of the Claim are disputed, unless the 45-day period is extended by mutual agreement of City and Contractor or as otherwise allowed under Public Contract Code § 9204. However, if City determines that the Claim is not adequately substantiated pursuant to Section 12.2(A), Substantiation, City may first request in writing, within 30 days of receipt of the Claim, any additional documentation supporting the Claim or relating to defenses to the Claim that City may have against the Claim. (A) Additional Information. If additional information is thereafter required, it may be requested and provided upon mutual agreement of City and Contractor. If Contractor’s Claim is based on estimated amounts, Contractor has a continuing duty to update its Claim as soon as possible with information on actual amounts in order to facilitate prompt and fair resolution of the Claim. Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 72 (B) Non-Waiver. Any failure by City to respond within the times specified above will not be construed as acceptance of the Claim, in whole or in part, or as a waiver of any provision of these Contract Documents. 12.4 Meet and Confer. If Contractor disputes City’s written response, or City fails to respond within the specified time, within 15 days of receipt of City’s response or within 15 days of City’s failure to respond within the applicable 45-day time period under Section 12.3, respectively, Contractor may notify City of the dispute in writing sent by registered or certified mail, return receipt requested, and demand an informal conference to meet and confer for settlement of the issues in dispute. If Contractor fails to dispute City’s response in writing within the specified time, Contractor’s Claim will be deemed waived. (A) Schedule Meet and Confer.

Within ten working days after the meet and confer has concluded, City will issue a written statement identifying which portion(s) of the Claim remain in dispute, if any. (D) Submission to Mediation. If the Claim or any portion remains in dispute following the meet and confer conference, within ten working days after the City issues the written statement identifying any portion(s) of the Claim remaining in dispute, the Contractor may identify in writing disputed portion(s) of the Claim, which will be submitted for mediation, as set forth below. 12.5 Mediation and Government Code Claims. (A) Mediation. Within ten working days after the City issues the written statement identifying any portion(s) of the Claim remaining in dispute following the meet and confer, City and Contractor will mutually agree to a mediator, as provided under Public Contract Code § 9204. Mediation will be scheduled to ensure the mutual availability of the selected mediator and all of the individuals that each party requires to represent its interests. If there are multiple Claims in dispute, the parties may agree to schedule the mediation to address all outstanding Claims at the same time. The parties will share the costs of the mediator and mediation fees equally, but each party is otherwise solely and separately responsible for its own costs to prepare for and participate in the mediation, including costs for its legal counsel or any other consultants. (B) Government Code Claims. (1) Timely presentation of a Government Code Claim is a condition precedent to filing any legal action based on or arising from the Contract. Compliance with the Claim submission requirements in this Article 12 is a condition precedent to filing a Government Code Claim. (2) The time for filing a Government Code Claim will be tolled from the time Contractor submits its written Claim pursuant to Section 12.2, above, until the time that Claim is denied in whole or in part at the conclusion of the meet and confer process, including any period of time used by the meet and confer process. However, if the Claim is submitted to mediation, the time for filing a Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 73 Government Code Claim will be tolled until conclusion of the mediation, including any continuations, if the Claim is not fully resolved by mutual agreement of the parties during the mediation or any continuation of the mediation. 12.6 Tort Claims. This Article does not apply to tort claims and nothing in this Article is intended nor will be construed to change the time periods for filing tort-based Government Code Claims. 12.7 Arbitration. It is expressly agreed, under Code of Civil Procedure § 1296, that in any arbitration to resolve a dispute relating to this Contract, the arbitrator’s award must be supported by law and substantial evidence. 12.8 Burden of Proof and Limitations. Contractor bears the burden of proving entitlement to and the amount of any claimed damages. Contractor is not entitled to damages calculated on a total cost basis, but must prove actual damages.

The Eichleay Formula or similar formula will not be used for any recovery under the Contract. The City will not be directly liable to any Subcontractor or supplier. 12.9 Legal Proceedings. In any legal proceeding that involves enforcement of any requirements of the Contract Documents, the finder of fact will receive detailed instructions on the meaning and operation of the Contract Documents, including conditions, limitations of liability, remedies, claim procedures, and other provisions bearing on the defenses and theories of liability. Detailed findings of fact will be requested to verify enforcement of the Contract Documents. All of the City's remedies under the Contract Documents will be construed as cumulative, and not exclusive, and the City reserves all rights to all remedies available under law or equity as to any dispute arising from or relating to the Contract Documents or performance of the Work. 12.10 Other Disputes. The procedures in this Article 12 will apply to any and all disputes or legal actions, in addition to Claims, arising from or related to this Contract, including disputes regarding suspension or early termination of the Contract, unless and only to the extent that compliance with a procedural requirement is expressly and specifically waived by City. Nothing in this Article is intended to delay suspension or termination under Article 13. Article 13 - Suspension and Termination 13.1 Suspension for Cause. In addition to all other remedies available to City, if Contractor fails to perform or correct Work in accordance with the Contract Documents, including non-compliance with applicable environmental or health and safety Laws, City may immediately order the Work, or any portion of it, suspended until the circumstances giving rise to the suspension have been eliminated to City’s satisfaction. (A) Notice of Suspension. Upon receipt of City’s written notice to suspend the Work, in whole or in part, except as otherwise specified in the notice of suspension, Contractor and its Subcontractors must promptly stop Work as specified in the notice of suspension; comply with directions for cleaning and securing the Worksite; and protect the completed and in-progress Work and materials. Contractor is solely responsible for Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 74 any damages or loss resulting from its failure to adequately secure and protect the Project. (B) Resumption of Work. Upon receipt of the City’s written notice to resume the suspended Work, in whole or in part, except as otherwise specified in the notice to resume, Contractor and its Subcontractors must promptly re-mobilize and resume the Work as specified; and within ten days from the date of the notice to resume, Contractor must submit a recovery schedule, prepared in accordance with the Contract Documents, showing how Contractor will complete the Work within the Contract Time. (C) Failure to Comply. Contractor will not be entitled to an increase in the Contract Time or Contract Price for a suspension occasioned by Contractor’s failure to comply with the Contract Documents. (D) No Duty to Suspend. City’s right to suspend the Work will not give rise to a duty to suspend the Work, and City’s failure to suspend the Work will not constitute a defense to Contractor’s failure to comply with the requirements of the Contract Documents. 13.2 Suspension for Convenience. City reserves the right to suspend, delay, or interrupt the performance of the Work in whole or in part, for a period of time determined to be appropriate for City’s convenience. Upon notice by City pursuant to this provision, Contractor must immediately suspend, delay, or interrupt the Work and secure the Project site as directed by City except for taking measures to protect completed or in- progress Work as directed in the suspension notice, and subject to the provisions of Section 13.1(A) and (B), above. If Contractor submits a timely request for a Change Order in compliance with Articles 5 and 6, the Contract Price and the Contract Time will be equitably adjusted by Change Order pursuant to the terms of Articles 5 and 6 to reflect the cost and delay impact occasioned by such suspension for convenience, except to the extent that any such impacts were caused by Contractor’s failure to comply with the Contract Documents or the terms of the suspension notice or notice to resume. However, the Contract Time will only be extended if the suspension causes or will cause unavoidable delay in Final Completion. If Contractor disputes the terms of a Change Order issued for such equitable adjustment due to suspension for convenience, its sole recourse is to comply with the Claim procedures in Article 12. 13.3 Termination for Default. City may declare that Contractor is in default of the Contract for a material breach of or inability to fully, promptly, or satisfactorily perform its obligations under the Contract. (A) Default. Events giving rise to a declaration of default include Contractor’s refusal or failure to supply sufficient skilled workers, proper materials, or equipment to perform the Work within the Contract Time; Contractor’s refusal or failure to make prompt payment to its employees, Subcontractors, or suppliers or to correct defective Work or damage; Contractor’s failure to comply with Laws, or orders of any public agency with jurisdiction over the Project; evidence of Contractor’s bankruptcy, insolvency, or lack of financial capacity to complete the Work as required within the Contract Time; suspension, revocation, or expiration and nonrenewal of Contractor’s license or DIR registration; dissolution, liquidation, reorganization, or other major change in Contractor’s organization, ownership, structure, or existence as a business entity; unauthorized assignment of Contractor’s rights or duties under the Contract; or any material breach of the Contract requirements. (B) Notice of Default and Opportunity to Cure. Upon City’s declaration that Contractor is in default due to a material breach of the Contract Documents, if City determines that the default is curable, City will afford Contractor the opportunity to cure Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 75 the default within ten days of City’s notice of default, or within a period of time reasonably necessary for such cure, including a shorter period of time if applicable. (C) Termination. If Contractor fails to cure the default or fails to expediently take steps reasonably calculated to cure the default within the time period specified in the notice of default, City may issue written notice to Contractor and its performance bond surety of City’s termination of the Contract for default. (D) Waiver. Time being of the essence in the performance of the Work, if Contractor’s surety fails to arrange for completion of the Work in accordance with the Performance Bond within seven calendar days from the date of the notice of termination pursuant to paragraph (C), City may immediately make arrangements for the completion of the Work through use of its own forces, by hiring a replacement contractor, or by any other means that City determines advisable under the circumstances. Contractor and its surety will be jointly and severally liable for any additional cost incurred by City to complete the Work following termination, where “additional cost” means all cost in excess of the cost City would have incurred if Contactor had timely completed Work without the default and termination. In addition, City will have the right to immediate possession and use of any materials, supplies, and equipment procured for the Project and located at the Project site or any Worksite on City property for the purposes of completing the remaining Work. (E) Compensation. Within 30 days of receipt of updated as-builts, all warranties, manuals, instructions, or other required documents for Work installed to date, and delivery to City of all equipment and materials for the Project for which Contractor has already been compensated, Contractor will be compensated for the Work satisfactorily performed in compliance with the Contract Documents up to the effective date of the termination pursuant to the terms of Article 8, Payment, subject to City’s rights to withhold or deduct sums from payment otherwise due pursuant to Section 8.3, and excluding any costs Contractor incurs as a result of the termination, including any cancellation or restocking charges or fees due to third parties. If Contractor disputes the amount of compensation determined by City, its sole recourse is to comply with the Claim Procedures in Article 12, by submitting a Claim no later than 30 days following notice from City of the total compensation to be paid by City. (F) Wrongful Termination. If Contractor disputes the termination, its sole recourse is to comply with the Claim procedures in Article 12. If a court of competent jurisdiction or an arbitrator later determines that the termination for default was wrongful, the termination will be deemed to be a termination for convenience, and Contractor’s damages will be strictly limited to the compensation provided for termination for convenience under Section 13.4, below. Contractor waives any claim for any other damages for wrongful termination including special or consequential damages, lost opportunity costs, or lost profits, and any award of damages is subject to Section 12.8, Burden of Proof and Limitations. 13.4 Termination for Convenience. City reserves the right, acting in its sole discretion, to terminate all or part of the Contract for convenience upon written notice to Contractor. (A) Compensation to Contractor. In the event of City’s termination for convenience, Contractor waives any claim for damages, including for loss of anticipated profits from the Project. The following will constitute full and fair compensation to Contractor, and Contractor will not be entitled to any additional claim or compensation: (1) Completed Work. The value of its Work satisfactorily performed as of the date notice of termination is received, based on Contractor’s schedule of values Wilson Park Basketball Court GENERAL CONDITIONS Project No. 2022-11 Page 76 and unpaid costs for items delivered to the Project site that were fabricated for incorporation in the Work; (2) Demobilization. Demobilization costs specified in the schedule of values, or if demobilizations cost were not provided in a schedule of values pursuant to Section 8.1, then based on actual, reasonable, and fully documented demobilization costs; and (3) Termination Markup. Five percent of the total value of the Work performed as of the date of notice of termination, including reasonable, actual, and documented costs to comply with the direction in the notice of termination for convenience, and demobilization costs, which is deemed to cover all overhead and profit to date. (B) Disputes. If Contractor disputes the amount of compensation determined by City pursuant to paragraph (A), above, its sole recourse is to comply with the Claim procedures in Article 12, by submitting a Claim no later than 30 days following notice from City of total compensation to be paid by City. 13.5 Actions Upon Termination for Default or Convenience. The following provisions apply to any termination under this Article, whether for default or convenience, and whether in whole or in part. (A) General. Upon termination City may immediately enter upon and take possession of the Project and the Work and all tools, equipment, appliances, materials, and supplies procured or fabricated for the Project. Contractor will transfer title to and deliver all completed Work and all Work in progress to City. (B) Submittals. Unless otherwise specified in the notice of termination, Contractor must immediately submit to City all designs, drawings, as-built drawings, Project records, contracts with vendors and Subcontractors, manufacturer warranties, manuals, and other such submittals or Work-related documents required under the terms of the Contract Documents, including incomplete documents or drafts.

Upon completion of all termination obligations, as specified herein and in the notice of termination, Contractor will submit its request for Final Payment, including any amounts due following termination pursuant to this Article 13. Payment will be made in accordance to the provisions of Article 8, based on the portion of the Work satisfactorily completed, including the close out requirements, and consistent with the previously submitted schedule of values and unit pricing, including demobilization costs.

Where no limit of the Tree and Plant Protection area is Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 93 defined on the drawings, the limit shall be the drip line (outer edge of the branch crown) of each tree. 1. Prior to any construction activity at the site including utility work, grading, storage of materials, or installation of temporary construction facilities, install all tree protection fencing, Filter Fabric, silt fence, tree protection signs, Geogrid, Mulch and or Wood Chips as shown on the drawings, or as designated by the Project Arborist. F. No vehicle parking or equipment storage shall be allowed within drip lines of trees not designated for removal. 1. If unavoidable vehicle traffic within the tree protection zone is necessary, protection of the soil to reduce compaction must be accomplished through one of the following: a. Apply 6-12” of woodchip mulch to the area. b. Lay plywood or 4x4 wood beams over a 4” thick layer of wood chip mulch. c. Apply 4 to 6” of gravel over a taut, staked geotextile fabric. d. Placing commercial matting on top of a 4” thick woodchip mulch later. 2. Materials exceeding 4” in depth shall be removed after work in the area has been completed, to allow the roots to breath. G. No dumping of cement tailings, chemicals or other waste products into any future landscape area and the tree protection area. Storage of materials, refuse, excavated spoils or dumping of poisonous materials on or around trees and roots. Poisonous materials include, but are not limited to, paint, petroleum products, concrete or stucco mix, dirty water or any other material which may be deleterious to tree health. H. The use of tree trunks as a winch support, anchorage, as a temporary power pole, sign posts or other similar function is prohibited within the tree protection fence. I. Trees to be removed/demolished shall be chipped on site. Store chips onsite in an area designated by the City’s Representative or within tree protection zones. These chips shall be used as mulch for trees to remain as determined by the City’s representative or consulting arborist. Trees with allelopathic inhibitors, such as Black Walnut or Eucalyptus, are not allowed to be chipped and used on site, but must be hauled off site. J. Any damage or injury to trees shall be reported within six hours (6 hr.) to the Project Arborist and job superintendent so that mitigation can take place. All mechanical or chemical injury to branches, trunk or to roots over two inches (2”) in diameter shall be reported in the monthly inspection report. 1. Root injury: SEE 3.04 Root Treatment. 2. Bark or trunk wounding: Current bark tracing and treatment methods shall be performed by a qualified tree care specialist within two (2) days. 3. Scaffold branch or leaf canopy injury: Remove broken or torn branches back to an appropriate branch capable of resuming terminal growth within five (5) days. If leaves are heat scorched from equipment exhaust pipes, consult the Project Arborist within six (6) hours. 3.2 PRE-DEMOLITION / CONSTRUCTION A. The demolition contractor shall meet with the City’s representative before Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 94 beginning work to discuss work procedures and tree protection. No cutting of any part of project trees, including roots, shall be done without securing approval and direct supervision from the City. B. Contractor shall tag and identify existing trees which are to remain within the project limits PRIOR to start of any work. Tree Protection fencing as described in 3.01 D shall be installed. C. Existing groundcover or lawn shall be left in place and not ripped out until necessary and permanent irrigation and mulch is installed. When clearing is required, it shall be accomplished with hand-operated equipment. D. Pruning 1. Pruning shall be performed by a qualified tree service with an ISA Certified Arborist on staff, in a supervisory position for the work, and pre-approved by the Project Arborist. The tree pruner shall follow the most current version of the arboriculture industry standards- See References. 2. Pruning protected trees prior to construction should be as little as possible, and only what is required for demolition and construction clearance from structures and activities. Trees shall be pruned to reduce hazards and develop a strong framework. Aesthetic pruning can be done later, if necessary. Branches that must be shortened should be cut back to appropriately sized lateral branches whenever possible, and not to stubs. 3. If urgent pruning is necessary for immediate construction clearance this may be done by the general or demolition contractor. In this case a short stub should be left which can be removed by a qualified tree service at a later time. Please consult with the arborist prior to such pruning. 4. Where temporary clearance is needed for access, branches shall be tied back to hold them out of the clearance zone. 5. Pruning shall not be performed during periods of flight of adult boring insects because fresh wounds attract pests. Pruning shall be performed only when the danger of infestation is past. 6. Pruning cuts that expose heartwood and are larger than 4” in diameter shall be avoided. 7. No more than 25% of foliage shall be removed within the trees. 8. Interior branches shall not be stripped out. 9. Tree(s) to be removed that have branches extending into the canopy of tree(s) to remain must be removed by an International Society of Arboriculture (ISA) qualified arborist or tree worker and not by demolition or construction contractors. The qualified arborist shall remove the tree in a manner that causes no damage to the tree(s) and understory to remain. 10. Where tree specific disease vectors require, sterilize all pruning tools between the work in individual trees, per ISA standards. E. Tree Root Pruning 1. Root prune as directed by the Project Arborist, if required. F. Mulch 1. Refer to 3.06 MULCH below for further information. G. Fertilizer 1. Apply a single dose of fertilizer to protected trees per the Project Arborist Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 95 recommendation prior to construction, if required. 3.3 FENCING AND SIGNAGE A. Before any construction may commence, the Contractor shall provide and install temporary fencing to protect all existing trees and vegetation not designated for removal. Protective fencing shall be placed at a distance of 6 times the diameter of the tree’s trunk measured 4.5 feet above the natural grade. B. If fence must be placed on an impermeable surface, the post must be inserted into post stands. If the impervious surface is later removed, the posts must be replaced into the ground. C. Allow a 24” gap between one set of posts to provide access for tree work and monitoring. D. If it is not possible to fence a tree, then the Contractor shall wrap the trunk with 2” x 4” vertically stacked lumber from the ground up, with a gap of 1” to 2” between the boards, fastened to the tree with rope or metal straps at the top, bottom and middle of its height. The lumber is then wrapped in 2 layers of orange plastic ski fencing. Such trees also require ground protection underneath as much of the dripline as possible. E. Tree protection signage shall be posted on the fencing every 20 feet and attached with ties on all four corners. Signage shall proclaim that there shall be no unauthorized work or persons within the tree protection zone, no dumping of chemicals or storage of materials or equipment, and who to contact regarding this. 3.4 TREE ROOT TREATMENT A. Preconstruction root exploration is necessary for all existing trees adjacent to trenching, grade reduction or other activities that require exposure or removal of soil from the critical root zone. Roots shall be located using non-invasive exploration procedures, such as hand digging using small tools, pressurized water or a pneumatic air device, such as an Air-Spade®. This tool uses compressed air to displace soil without damage to roots. Once exposed, the roots can be examined and determinations by the City’s representative and/or the Project Arborist are made regarding the feasibility of root removal or root severance. B. Contractor shall notify the City’s Representative if any roots over 2” in diameter are required to be cut. In this case, all work within the drip line of the tree shall be suspended until notified by the City’s Representative and/or Project Arborist. C. Methods of root pruning (in order of preference): 1. Selective root cutting after exposing the roots as indicated in 3.04A, leaving roots intact (digging underneath) when possible. 2. Cutting roots with a root cutting machine (e.g. Dosco or Vermeer root pruner) along a predetermined line on the surface. Cleanly cut necessary roots. Bark should adhere to the wood without tearing. Wood fibers should remain intact without shattering. 3. Mechanically excavating (e.g. with trencher or backhoe) and hand pruning what is left of the roots. Work slowly and have ground crew cleanly cut roots as soon as possible after encountered. D. The following tools are acceptable for use: Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 96 1. Round blade shovel 2. Tree pruning handsaw designed for root cutting 3. Hand pruners 4. Loppers with 1 inch capacity reciprocating saw with wood cutting blade 5. Concrete circular saw (rock or root cutting saw, e.g. Stihl TS-400 with 12” blade, preferably carbon-tipped- start with new blade). 6. Chainsaw (for large roots over 4 inches in diameter- start with new chain). E. Proper pruning technique shall encourage callusing of the roots. Root cutting and removal shall not exceed thirty-five (35%) of total root surface. F. Exposed Roots 1. Temporarily cover exposed roots with wet burlap to prevent roots from drying out, maintain moist condition of burlap at all times and remove burlap and cover with earth as soon as possible (within two hours). If the air temperature is 80 degrees Fahrenheit or greater, the burlap must be inspected every hour and re-wet as necessary to maintain a constant cool moist condition. If air temperature is below 80 degrees Fahrenheit, the burlap must be inspected every 4 hours and re-wet as necessary to maintain a constant cool moist condition. Small roots can dry out and die in 10-15 minutes. Larger roots can succumb in an hour or less under unfavorable weather conditions. G. Injured / Damaged Roots 1. Any roots damaged during grading or construction shall be exposed to sound tissue and cut cleanly with approved tools/equipment. Crushed or torn roots are more likely to allow decay to begin; sharply cut roots produce a flush of new roots helping the tree to recover from injury. If any roots over two inches (2”) in diameter are severed during any excavation, the following procedure shall be followed: a. The roots shall be shaded by immediately covering the entire trench with plywood, or by covering the sides of the trench with burlap sheeting that is kept moist by watering twice (2x) per day. b. When ready to backfill, each root shall be severed cleanly with a handsaw. Where practical, they should be cut back to a side root or 2” behind the ragged end. Immediately, a plastic bag shall be placed over the fresh cut, and secured with a rubber band or electrical tape. Shading should immediately be placed until backfilling occurs. c. Plastic bags shall be removed prior to backfilling. d. Backfill shall be clean, native material free of debris, gravel or wood chips. H. Contractor shall pay the City the value of existing trees to remain that died or were damaged because of the contractor's failure to provide adequate protection and maintenance. In accordance with the schedule of values, using "tree caliper" method established in the most recent issue of the guide for establishing values of tree and other plants prepared by the council of tree if it is determined that the contractor has willfully or negligently damaged or destroyed the existing trees to remain, the values shall be tripled to reimburse City for inconvenience and damages. 3.5 TRENCHING / SITE WORK Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 97 A. Demolition 1. Removal of existing pavement must be done carefully and slowly around protected trees. Jack hammering pavement to break into manageable pieces to be hand removed is preferred. SEE 3.6 MULCH for additional information. B. Grading 1. If heavy grading equipment is used around the protected trees and roots are encountered that must be removed, grading must stop and the roots shall be cut immediately by the above methods. Tearing back roots toward the trunk to snap them or break them by continuing to operate heavy equipment is not acceptable. 2. When using heavy machinery around protected trees, the equipment shall sit on existing pavement and work backwards so as to remain on the pavement or otherwise outside the tree protection zones, or at least as far away from the trunk as possible. Machine operator shall work very slowly, removing soil in 6 inch lifts. Contractor shall have a ground crew with shovels to watch for and expose tree roots while the machines are excavating. The equipment operator should ‘feel’ for roots while excavating around protected trees and notify ground crew to cut roots per the above methods if the roots are smaller than 2”. 3. Soil Compaction: If compaction of the soil occurs, it shall be mitigated as outlined in Soil Compaction Damage, and/or Soil Improvement. 4. Grading Limitations within the Tree Protection Zone (TPZ): a. Grade changes outside of the TPZ shall not significantly alter drainage to the tree. b. Grade changes within the TPZ are not permitted. c. Grade changes under specifically approved circumstances shall not allow more than six (6) inches of fill soil added or allow more than four (4) inches of existing soil to be removed from natural grade unless mitigated. C. Trenching 1. Spoil from trench, footing, utility or other excavation shall not be placed within the tree protection zone, neither temporarily or permanently. 2. All underground utilities, drain lines or irrigation lines shall be routed outside the tree protection zone. If lines must traverse through the protection area, they shall be tunneled or bored under the tree as directed by the City/Project Arborist. 3. Open trenching in the root zone of any tree is prohibited except in cases where the trenching fall outside the drip-line of the tree involved. Exception will be allowed if, in the opinion of the Project Arborist, the impact of trenching upon the tree will be negligible. Project Arborist approval is required. 4. In the event trenches for irrigation and/or lighting are required within a tree’s canopy, they shall be installed by hand in a radial direction to the trees’ trunks. If irrigation trenches cannot be routed as such, the work may need to be performed using a pneumatic air device, such as an Air-Spade®, to avoid unnecessary root damage. 3.6 MULCHING A. Apply 4-6” of wood chip mulch within the tree protection zone and maintain during Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 98 construction. Mulch material may be chipped trees from on-site demolished trees. Contractor shall maintain 6-12” clear around the base of the trunk. The mulch will help regenerate new fine roots in the soil just beneath the mulch. This can help to compensate for some of the root loss or root damage that trees experience. B. If pavement is removed within the tree protection zone, the contractor shall wet the soil underneath the removed pavement to a maximum depth of 6”, and apply mulch per above. 3.7 CLEAN-UP A. During tree and plant protection work, keep the site free of trash, pavements reasonably clean and work area in an orderly condition at the end of each day. Remove trash and debris in containers from the site no less than once a week. B. Immediately clean up any spilled or tracked soil, fuel, oil, trash or debris deposited by the Contractor from all surfaces within the project or on public right of ways and neighboring property. C. Once tree protection work is complete, wash all soil from pavements and other structures. Ensure that Mulch is confined to planting beds. D. Make all repairs to grades, ruts, and damage to the work or other work at the site. E. Remove and dispose of all excess Mulch, Wood Chips, packaging, and other material brought to the site by the Contractor. 3.8 REMOVAL OF FENCING AND OTHER TREE AND PLANT PROTECTION A. At the end of the construction period or when requested by the City’s Representative remove all fencing, Wood Chips or Mulch, Geogrids and Filter Fabric, trunk protection and or any other Tree and Plant Protection material. 3.9 DAMAGE OR LOSS TO EXISTING PLANTS TO REMAIN A. Any trees or plants designated to remain and which are damaged by the Contractor shall be replaced in kind by the Contractor at their own expense. Trees shall be replaced with a tree of similar species and of equal size or 6 inch caliper whichever is less. Shrubs shall be replaced with a plant of similar species and equal size or the largest size plants reasonably available whichever is less. Where replacement plants are to be less than the size of the plant that is damaged, the City’s Representative shall approve the size and quality of the replacement plant. B. All trees and plants shall be installed per the requirements of Specification Section Planting Work. C. Plants that are damaged shall be considered as requiring replacement or appraisal in the event that the damage affects more than 25 % of the crown, 25% of the trunk circumference, or root protection area, or the tree is damaged in such a manner that the tree could develop into a potential hazard. Trees and shrubs to be replaced shall be removed by the Contractor at his own expense. D. The City's Representative may engage an independent arborist to assess any tree or plant that appears to have been damaged to determine their health or condition. E. Any tree that is determined to be dead, damaged or potentially hazardous by the City’s arborist and upon the request of the City’s Representative shall be immediately removed by the Contractor at no additional expense to the City. Tree Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 99 removal shall include all cleanup of all wood parts and grinding of the stump to a depth sufficient to plant the replacement tree or plant, removal of all chips from the stump site and filling the resulting hole with topsoil. F. Any remedial work on damaged existing plants recommended by the consulting arborist shall be completed by the Contractor at no cost to the City. Remedial work shall include but is not limited to: soil compaction remediation and vertical mulching, pruning and or cabling, insect and disease control including injections, compensatory watering, additional mulching, and could include application tree growth regulators (TGR). G. Remedial work may extend up to two years following the completion of construction to allow for any requirements of multiple applications or the need to undertake applications at required seasons of the year.

Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 154 D. The surface shall be flooded. Any ponding water remaining that is deep enough to cover the thickness of a five-cent piece shall be corrected using a patch mix consisting of Novabond, 50-mesh sand and Portland cement, as per manufacturers’ directions. Depressions must be primed with a 50% dilution of Novabond and water prior to patching. E. Application shall proceed only if the surface is dry and clean and the temperature is at least fifty degrees (50°F) and rising, and the surface temperature is not in excess of one hundred forty degrees (140°F). Do not apply coatings when rain is imminent. F. Each coat in this system must dry completely before next application. Between each coat, inspect entire surface. Any defects should be repaired. Scrape surface to remove any lumps, and broom or blow off all loose matter. G. Using a neoprene rubber squeegee, apply one (1) coat of Novasurface acrylic resurfacer, diluted with one (1) part clean water, to two (2) parts Novasurface. Clean, bagged sand shall be incorporated into the diluted Novasurface at the rate of five (5) to ten (10) Lbs. per gallon. Sand gradation shall be 50 to 60-mesh. Allow application to dry thoroughly. H. Using a neoprene rubber squeegee, apply two (2) coats of Novaplay (colors to be designated by the City). Allow each application to dry thoroughly. A small (not to exceed 8 fl. oz per gal.) quantity of water may be used in diluting these coatings, only if coatings are drying too rapidly. Permission of the City shall be obtained before adding additional water. 3.2 LINE MARKINGS A. Upon completion and acceptance of the surface, this Contractor shall prepare and paint lines. B.

Upon completion, the contractor shall insure proper removal of all construction debris, surplus materials, empty containers and wash water, and shall leave the site in a condition acceptable to the City. The court is to be left secure so as to prevent vandalism. 3.4 LIMITATIONS A. Apply coatings only when ambient temperature is fifty degrees (50°F) and rising, and the surface temperature is not in excess of one hundred forty degrees (140°F). Wilson Park Basketball Court TECHNICAL SPECIFICATION Project No. 2022-11 Page 155 B. All NOVACRYLIC coatings are waterborne and cannot cure in cold temperatures or when subject to moisture. Care should be taken not to apply coatings when rain is forecast or sudden drop of temperature is expected. Climatic conditions such as very cool evenings and high dew points dictate that work should be completed early in the day so the coatings can be exposed to enough warm sunlight to form a film before sunset. The opposite applies during times of high heat, low humidity and drying breezes: under these conditions, work very early in the morning or very late in the day. If the product seems to be drying too fast in hot weather, mist the pavement with water to make the application easier. Care must be taken to allow each application to dry thoroughly prior to recoating.

The purpose of our investigation is to provide information regarding the surface and subsurface soil conditions at the site and provide geotechnical recommendations for the design and construction of the proposed basketball court. Conclusions and recommendations related to site grading and drainage are presented herein. This work included site reconnaissance, subsurface exploration, soil sampling, laboratory testing, engineering analysis, and preparation of this report. The scope of services for this investigation is outlined in our agreement dated August 23, 2021. The recommendations contained in this report are subject to the limitations presented in Section 8.0 of this report. The Association of Engineering Firms Practicing the Geosciences has produced a pamphlet for your information titled Important Information About Your Geotechnical Report. This pamphlet has been included with the copies of your report. 2.0 FIELD EXPLORATION AND LABORATORY TESTING PROGRAMS Our field exploration program included drilling, logging, and interval sampling of 3 borings advanced on September 21, 2021, with 6-inch diameter solid stem augers mounted on a truck rig. The borings were advanced to depths of 11 ½ feet below existing grade. Details of the field exploration program, including the Boring Logs, are presented in Appendix B, Figures B4 through B-6. Representative samples obtained during the field investigation were taken to the laboratory for testing to determine physical and engineering properties. Details of the laboratory testing program are outlined in Appendix C. Test results are presented on the Boring Logs and in Appendix C. 3.0 SITE DESCRIPTION 3.1 Location The project site is located southwest of Highway 280 in Cupertino, California. The site location is shown on the Site Location Plan, Appendix B, Figure B-1. Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 4 3.2 Surface Conditions Wilson Park is approximately 10 acres in size, is relatively level, and is improved with greenspace, baseball fields, play structures, a building, paved walkways, and other improvements. The area of the proposed development is located in the southeastern portion of the park. This area is bordered by a paved walkway to the north, a baseball field to the west, the park boundary to the south, and barbeque areas to the east. The area is relatively level with minor changes in gradients related to the shaping of the site during the original construction of the park. The site is vegetated with grass, which is dried out as the irrigation has been turned off. The ground surface is desiccated with ground cracks up to ½ inch wide. 3.3 Subsurface Conditions A total of 3 borings were advanced to depths of 11 ½ feet below existing grade. The site is mapped as being underlain by alluvium. This is consistent with our field exploration. The borings generally encountered 4 ½ to 5 ½ feet of stiff lean to fat clay overlying medium dense to dense gravel to the maximum depth drilled at 11 ½ feet. Groundwater was not encountered in any of the borings. The depth to groundwater will vary seasonally. 4.0 PROJECT DESCRIPTION Based on our discussions with the client, the project consists of constructing an asphalt or concrete basketball court and some minor grading in the adjacent area. 5.0 GEOTECHNICAL HAZARDS 5.1 General In our opinion, the geotechnical hazards that could potentially affect the proposed project are: • Intense seismic shaking • Collateral seismic hazards Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 5 5.2 Intense Seismic Shaking Intense seismic shaking may occur at the site during the design lifetime of the proposed structure from an earthquake along one of the local fault systems. Generally, the intensity of shaking will increase the closer the site is to the epicenter of an earthquake, however, seismic shaking is a complex phenomenon and may be modified by local topography and soil conditions. The transmission of earthquake vibrations from the ground into the structure may cause structural damage. The City of Cupertino has adopted the seismic provisions set forth in the 2019 California Building Code to address seismic shaking. The seismic provisions in the 2019 CBC are minimum load requirements for the seismic design for the proposed structure. The provisions set forth in the 2019 CBC will not prevent structural and nonstructural damage from direct fault ground surface rupture, coseismic ground cracking, liquefaction and lateral spreading, seismically induced differential compaction, seismically induced landsliding, or seismically induced inundation. Table 1 has been constructed based on the 2019 CBC requirements as adopted from the ASCE 7 provisions for the seismic design of the proposed structure. The Site Class has been determined based on our field investigation and laboratory testing. Table 1.

It is our opinion that these hazards are low. 6.0 DISCUSSIONS AND CONCLUSIONS The site is underlain by 4 ½ to 5 ½ feet of lean to fat clay with a moderate to high potential for expansion. As part of our laboratory analysis, we completed one atterberg limits test which yielded a plasticity index of 28. The soil samples were collected in the middle of the summer during a drought. The irrigation in this portion of the park has been turned off. The clayey soil has dried out. Our firm attempted to run swell tests, but the soil was brittle and desiccated, which did not allow for running in-situ tests. Our firm observed the adjacent hardscape. This included the adjacent asphalt concrete walkway and circular concrete barbeque pad. These features have significant cracks consistent with being subject to shrink/swell cycles of the underlying clay. 7.0 RECOMMENDATIONS 7.1 General Based on the results of our field investigation, laboratory testing, and engineering analysis it is our opinion that from the geotechnical standpoint, the subject site will be suitable for the asphalt or concrete basketball court. The basketball court should be underlain by a minimum of 24 inches of non-expansive engineered fill. 7.2 Site Grading 7.2.1 Site Clearing The site should be cleared of loose soil, fill, organics, and debris within the project limits. 7.2.2 Preparation of On-Site Soils The proposed concrete basketball court should be over-excavated a minimum of 24 inches below the base of the proposed basketball court. This should extend a minimum of 2 feet beyond the edge of the concrete. The exposed soil should be scarified a minimum of 12 inches, moisture conditioned to 2 to 4 percent over optimum moisture, and compacted to 88 to 90 percent relative compaction. Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 7 Imported select fill should then be placed to design subgrade. All select fill should be compacted with heavy vibratory equipment. Select fill should be compacted by mechanical means in uniform horizontal loose lifts not exceeding 8 inches in thickness. The relative compaction and required moisture content shall be based on the maximum dry density and optimum moisture content obtained in accordance with ASTM D1557. Engineered fill should be compacted to a minimum of 90 percent relative compaction. The on-site clayey soil may not be re-used as select fill beneath the basketball court. The on-site clayey soil may be used for landscape berms within the park. This material may be placed at a minimum of 85 percent relative compaction at 0 to 2 percent over-optimum moisture. Imported select fill material should be approved by a representative of Butano Geotechnical Engineering, Inc. prior to importing. Imported fill should be primarily granular with no material greater than 2½ inches in diameter and no more than 20 percent of the material passing the #200 sieve. The fines fraction of the fill should not consist of expansive material. The Geotechnical Engineer should be notified not less than 5 working days in advance of placing any fill or base course material proposed for import. Each proposed source of import material should be sampled, tested, and approved by the Geotechnical Engineer prior to delivery of any soils imported for use on the site. Any surface or subsurface obstruction, or questionable material encountered during grading, should be brought immediately to the attention of the Geotechnical Engineer for proper processing as required. 7.2.3 Cut and Fill Slopes Minor cut and fill slopes related to landscaping berms are anticipated for this project. Permanent cut and fill slopes utilizing the on-site clayey soil should be no steeper than 3:1 (H:V). 7.2.4 Excavating Conditions Excavation of the site may be accomplished with standard earthwork equipment. Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 8 7.2.5 Surface Drainage Positive drainage should be maintained away from the structures at a minimum gradient of 2 percent for 5 feet. 7.2.6 Utility Trenches Bedding material should consist of sand with SE not less than 30 which may then be jetted. The on-site clayey soils may not be utilized for trench backfill. Imported fill should be free of organic material and rocks over 2.5 inches in diameter. If sand is used, a 3 foot concrete plug should be placed in each trench where it passes under the exterior footings. Backfill of all exterior and interior trenches should be placed in thin lifts not to exceed 8 inches and mechanically compacted to achieve a relative compaction of not less than 95 percent in paved areas and 90 percent in other areas per ASTM D1557. Care should be taken not to damage utility lines. Utility trenches that are parallel to the sides of a building should be placed so that they do not extend below a line sloping down and away at an inclination of 2:1 H:V from the bottom outside edge of all footings. Trenches should be capped with 1 1/2 feet of relatively impermeable material. Import material must be approved by the Geotechnical Engineer prior to its use. Trenches must be shored as required by the local regulatory agency, the State of California Division of Industrial Safety Construction Safety Orders, and Federal OSHA requirements. 7.3 Plan Review The recommendations presented in this report are based on preliminary design information for the proposed project and on the findings of our geotechnical investigation. When completed, the Grading Plans, Foundation Plans and design loads should be reviewed by Butano Geotechnical Engineering, Inc. prior to Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 9 submitting the plans and contract bidding. Additional field exploration and laboratory testing may be required upon review of the final project design plans. 7.4 Observation and Testing Field observation and testing must be provided by a representative of Butano Geotechnical Engineering, Inc. to enable them to form an opinion regarding the adequacy of the site preparation, the adequacy of fill materials, and the extent to which the earthwork is performed in accordance with the geotechnical conditions present, the requirements of the regulating agencies, the project specifications, and the recommendations presented in this report. Any earthwork performed in connection with the subject project without the full knowledge of, and not under the direct observation of Butano Geotechnical Engineering, Inc., will render the recommendations of this report invalid. Butano Geotechnical Engineering, Inc. should be notified at least 5 working days prior to any site clearing or other earthwork operations on the subject project in order to observe the stripping and disposal of unsuitable materials and to ensure coordination with the grading contractor. During this period, a preconstruction meeting should be held on the site to discuss project specifications, observation and testing requirements and responsibilities, and scheduling. 8.0 LIMITATIONS The recommendations contained in this report are based on our field explorations, laboratory testing, and our understanding of the proposed construction. The subsurface data used in the preparation of this report was obtained from the borings drilled during our field investigation. Variation in soil, geologic, and groundwater conditions can vary significantly between sample locations. As in most projects, conditions revealed during construction excavation may be at variance with preliminary findings. If this occurs, the changed conditions must be evaluated by the Project Geotechnical Engineer and the Geologist, and revised recommendations be provided as required. In addition, if the scope of the proposed construction changes from the described in this report, our firm should also be notified. Our investigation was performed in accordance with the usual and current standards of the profession, as they relate to this and similar localities. No other warranty, expressed or implied, is provided as to the conclusions and professional advice presented in this report. This report is issued with the understanding that it is the responsibility of the Owner, or of his Representative, to ensure that the information and recommendations contained herein Geotechnical Investigation – Design Phase October 18, 2021 Wilson Park Project No. 21-257-SCL Cupertino, CA Page 10 are brought to the attention of the Architect and Engineer for the project and incorporated into the plans, and that it is ensured that the Contractor and Subcontractors implement such recommendations in the field. The use of information contained in this report for bidding purposes should be done at the Contractor’s option and risk. This firm does not practice or consult in the field of safety engineering. We do not direct the Contractor's operations, and we are not responsible for other than our own personnel on the site; therefore, the safety of others is the responsibility of the Contractor. The Contractor should notify the Owner if he considers any of the recommended actions presented herein to be unsafe. The findings of this report are considered valid as of the present date. However, changes in the conditions of a site can occur with the passage of time, whether they be due to natural events or to human activities on this or adjacent sites.

The borings were advanced with 6-inch diameter solid stem augers mounted on a truck drill rig. The Key to The Logs and the Logs of the Boring are included in Appendix B, Figures B-3 through B-6. The approximate locations of the borings are shown on the Boring Site Plan, Figure B-2. The borings were located in the field by tape measurements from known landmarks. Their locations as shown are therefore within the accuracy of such measurements. The soils encountered in the borings were continuously logged in the field by a representative of Butano Geotechnical Engineering, Inc. Bulk and relatively undisturbed soil samples for identification and laboratory testing were obtained in the field. These soils were classified based on field observations and laboratory tests. The classifications are accordance with the Unified Soil Classification System (USCS: Figure B-3).
