CC 03-06-2018 Exhibit Item No. 9 City Work Program - Civic Center Master Plan Remodel Options PortraitCity Hall Deficiencies •Building does not meet existing Life Safety building codes, much less Essential Facility code to support EOC. •Building can be braced to meet seismic requirements. •Electrical Service and distribution systems are at end of useful life, at capacity and need full replacement. Replacement parts not available. •1960’s era boiler and emergency generator need replacement. Generator should not be within building. Replacement parts not available. •Air handler, boiler, chiller equipment needs replacement. HVAC controls out dated and do not work properly. Replacement parts not available. •Communication and data systems will be difficult to maintain over time due to age and capacities. •Building configuration is inefficient and non-compliant •ADA accessibility issues with toilet rooms and elevator •Employees lack work and meeting space •EOC and Lobby spaces inefficient •Interior doors and finishes need updates and replacements •Abundant walled offices create inefficiencies and reduce natural lighting •Building is energy inefficient •Building envelop needs insulation and better energy windows. October 21, 2014 9 STRUCTURAL TERMS EXPLAINED Seismic/ Life Safety • Life safety criteria implies significant damage to structure and non structural systems • Facility relocation and downtime is anticipated • Repairs may be costly or infeasible Immediate Occupancy • Prescriptive code criteria for Immediate Occupancy implies stronger structure • Does not explicitly assure performance goals, relies on structural damage to absorb seismic energy • May require costly repairs and facility downtime following major earthquake Performance Based (Immediate Occupancy/ Fully Operational) • Performance based to provide tailored structure to meet resiliency goals • Explicit and quantified performance metrics for risk and life-cycle cost assessment • Effective use of currently available technology (seismic isolation, viscous damping) to meet long term goals CIVIC CENTER MASTER PLAN Appendix Page 351 October 21, 2014 10 EXISTING BUILDING ASSESSMENT MECHANICAL • All Mechanical Systems are 30+ years old, inefficient and need to be replaced • Current codes require systems to be relocated elsewhere as they are not allowed to be in the same space • Systems maintenance costs can be greatly reduced * ELECTRICAL • All Electrical Systems are past 30+ years old, innefficient and need to be replaced • Light Fixtures are not energy efficient and require replacement to meet current codes • Systems maintenance costs can be greatly reduced * PLUMBING • Existing plumbing fixtures are water inefficient • ADA issues with current restroom layout • Old piping infrastructure * Current building is operating inefficiently at $3.63/SF-yr & 106 kBTU/SF-yr (vs $1.00 / SF-yr & 25 kBTU/SF-yr for new buildings) CIVIC CENTER MASTER PLAN Appendix Page 352 October 21, 2014 11 EXISTING BUILDING ASSESSMENT ARCHITECTURAL IMPLICATIONS • Clay roofing tiles need to be removed and replaced with a lightweight material • Accessibility upgrades are needed throughout • Elevator and shaft needs to be replaced / enlarged • Main stair needs upgrading to accommodate exiting • Current facility does not meet requirements to house an EOC ARCHITECTURAL CHALLENGES • Majority of public interface are accessed through dark corridors or are in the basement • Lack of daylight in basement workspaces / meeting spaces • Current layout does not accommodate for projected 10% growth of city staff • Workstations are inefficient and inflexible CIVIC CENTER MASTER PLAN Appendix Page 353 October 21, 2014 13 A: LIFE SAFETY UPGRADE • Roof Reinforcement • Concrete Column Reinforcement (Fiber Wrap or secondary steel columns) • Additional shear walls at ground level (at all 4 corners of building • Seismic Bracing of MEP equipment • Mechanical Equipment Relocation / Replacement • Electrical
