Corrections:
• Please write your response to each comment on the line provided and please have all the
responses on one copy.

Plan Review Comments
[01/26/16] 2"d Comment: In general, most of the plan review comments from the 15t round were not
addressed. Many of the responses stated `Not Required, Minor, or Done.' Please read thru the
comments carefully. Since the majority of comments were not addressed, they were re -printed as
they are still applicable to the project. It is a requirement for the designer and the structural engineer
to contact the Plan Check Engineer Arnold Hom and set up a meeting. The building utilizes a
combination of shearwall and brace wall lines, but the clerestory addition at the rear exceeds the
conventions of brace wall framing. It is a requirement for the engineer to contact Arnold Hom.
RESPONSE
[05104/15] Sheet T, Project Data, Type of Construction: Specify building is Type V-B and building
is FULLY SPRINKLERED. Due to the amount of roof/ceiling demolition, building requires

[01/26/16) 2"d Comment: Building may still require sprinklers due to the amount of remodel work. On
the existing plans, specify the square footage of each room. If more than 75% of the existing
habitable space is remodeled, or more than 50% of the existing exterior wall is no longer existing
exterior walls, than fire sprinklers are required. See attached copy of the Cupertino Existing vs. New
Construction Matrix. It is a requirement for the designer to contact the Plan Check Engineer.

RESPONSE
32. [05/04/15] Sheet S3 Roof Plan and sheet S5 detail 6: Specify the drag load in pounds per lineal
foot for the truss blocks (per detail 6/S5).
[01/26/16] 2"d Comment: Building now uses a combination of brace wall systems and shearwall lines.
Some of the brace wall lines do not meet brace wall requirements (such as having holdowns within 10-
feet of the corner end, clerestory addition does not have brace walls/ shearwalls on all four sides, nail
spacing for brace walls and anchors not called out, etc.). Shearwall systems do not have collectors
shown, especially at the front entrance and interior sheanwalls.
RESPONSE
36. [05/04/15] Sheet S3: Provide details for all interior shearwall connections to the trusses/ roof
diaphragm above.
RESPONSE

the building. Specify type of wood used and spacing of members. Revise roof beam RB1 to be decay
resistant wood as it is exposed to the elements and connected back into the building and used as a
drag collector.
RESPONSE
39. [05/04/151 Sheet S2: Specify length of all sheanwalls (existing and new). Specify locations of all
holdowns (new and existing), specify their size, and specify a reference detail for any holdown
installation (into new and existing concrete). For details, specify type of epoxy used, depth of
embedment, and clearance from concrete. Specify minimum stem wall and footing dimensions.
RESPONSE
40. [05/04/15] Sheet S2: Provide talcs per ACI 318 Appendix D for holdowns installed into existing
concrete.
[01/26/16) 2"d Comment: Holdowns are still required for corner brace walls that are within 10-feet of
brace wall line corner. Also, plans clearly label some walls as shearwalls; shearwalls require
calculations and may require holdowns into existing concrete. This comment may still apply.
RESPONSE
41. [05/04/15] Sheet S2: For all shearwalls, provide a schedule that specifies its nailing pattern, type
of nail used, capacity in pounds per lineal feet, anchorage requirements to foundation and to roof
framing/ trusses/ double top plate above. Required for existing shearwalls as well.
RESPONSE
42. [05/04/15] Sheet S2: For the 2-foot-6-inch footings, specify the rebar requirements and provide
details.
[01/26/16] 2"d Comment: Footings F-1 and F-3 specify to use detail 71S4; no negative reinforcement is
provided for this footing and there are brace walls/ shearwalls/ Simpson strong walls above this
footing.
RESPONSE
43. [05/04/15] Sheet S2: Provide a different hatching pattern for all new foundations. It seems that
many of the Simpson strong walls occur on top of existing foundations; provide details and
calculations to substantiate this connection. Are there new foundations under all Simpson Strong
Walls?
RESPONSE
44. [05/04/15] Sheet S2: No calculations were provided for the lateral analysis of the building.
Provide talcs. Further comments may follow due to lack of information.
[01/2611612nd Comment: Plans still specify shearwalls in some locations, but brace wall lines in other
locations. Shearwalls require analysis/ calculations; none provided.
RESPONSE
45. [05/04/15] Sheet S2: Per ESR Report, mixing shearwalls with Simpson Strong Walls on the same
line requires a stiffness analysis. Include this in the talcs per comment 44.
[01/26/16] 2"d Comment: Clarify which lateral elements are brace wall lines and which are shearwall
lines. Original comment may still apply depending on the method of analysis.
RESPONSE
46. [05/04/15] Sheet S2: Call out reference detail for shearwall anchorage to foundation for
shearwalls connection to existing foundation.
RESPONSE
47. [05/04/15] Sheet S2: Show outline of grade beam that connects the patio's Simpson Strong Wall
foundations back into the building. Occurs around the perimeter of the Patio.
RESPONSE
48. [05/04/15] S4 details 1, 5, and 8: For shearwalls with a capacity greater than 400 plf nominal
stress (200 plf allowable stress), anchor bolt plates must be within 1/2-inch of the plywood. Per ANSI/
AF&PA SDPWS-2008 section 4.3.6.4.3. This is for cross grain (perpendicular to grain) bending.
Also, revise details 1 and 2 to specify 24-inches of depth from pad grade (crawl space grade) to
bottom of footing, per soils report. Also, show the Pad grade (interior grade) to be level. And specify
spacing of horizontal #4 rebar.
RESPONSE
49. [05104/151 S2: Specify if holdown epoxy anchorage into existing concrete will be done by
Engineer of Record or done by 3rd party Independent Testing Agency. If done by 3rd Party, complete
and fill out 2 copies of the Cupertino Special Inspections Form.
RESPONSE
50. [05/04/15] Sheet T: Provide a Special Inspections List, listing all required special inspections.
Specify which are done by engineer of record, and which are done by 3rd party inspection agency.
For example, (1) epoxy holdowns into existing concrete done by Engineer of Record (or by Special
Inspection Agency).
