Structural Study • WLC Architects, Inc. conducted existing conditions evaluation and needs analysis of 8 Fire Stations. • 7 of 8 stations require major modifications or replacement – Cost $59 Million. • Report recommends immediate corrective actions for Stations 32 & 39. • Subject to structural failure due to a significant seismic event, based on existing design and materials.
Structural Study Comprehensive structural assessment & mitigation options identified for Stations 32 & 39. Independent peer review by TMAD of structural deficiencies noted in WLC Architects and RM Byrd’s structural report for Stations 32 & 39. City Building Official evaluated study and peer review. Retrofit of stations 32 & 39 is not an option.
Fire Station 32 Structurally Deficient: • About half of the walls have only 50% of the required strength. • Conflicting design between rigidity of apparatus bay and adjacent living quarters. • Wall separating female dormitory from apparatus bay may result in catastrophic damage to the building during a seismic event.
Fire Station 32 Options: Partially retrofit existing fire station, estimated cost of $400,000. (possibly relocate some resources) Demolish and replace existing station on site with 4 bays & 7-8k sf, estimated cost of $5.2M (temporarily relocate to Shakey’s site) Demolish and relocate station to Shakey’s site with 5 bays & 14k to 15k sf, estimated cost of $7.4M
Fire Station 32 Partially retrofit fire station at existing site. Relocate some staff and equipment. Conclusion:
Fire Station 32 Alternative Location – Shakey’s Site
Fire Station 39 Second floor supporting walls are overstressed. Main beam supporting second floor overstressed by 200%. Second floor movement during major seismic event could create a catastrophic collapse. Northeast corner tower was compromised by earlier seismic activity and requires retrofit or removal. South window openings likely to collapse during a major seismic event. Structurally Deficient:
Fire Station 39 Options: Demolish and replace existing station on site at an estimated cost of $5M. Demolish and relocate to new site at estimated cost of $5M + the cost of land acquisition.
Fire Station 39 Temporarily vacate station within 30 days. Initiate design and entitlements on the replacement station Conclusion:
