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.

8 City Fire Stations

Fire Station 32
• 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.
5
Structurally Deficient:
Fire Station 32
• 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
6
Options:
Fire Station 32
• Partially retrofit fire station at existing site.
• Relocate some staff and equipment.

Conclusion:
Fire Station 32
8
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.
9
Structurally Deficient:
Fire Station 39
• 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.
10
Options:
Fire Station 39
• Temporarily vacate station within 30 days.
• Initiate design and entitlements on the replacement station

Conclusion:
