Floating Fireboat Station 35


San Francisco, CA


In joint venture, Swinerton-Power JV, is the Design-Builder for a first of its kind floating fireboat station in Northern California. Situated at Pier 22½ just behind the operational historic firehouse and nestled beside the Bay Bridge, the new Fire Station 35 will provide San Francisco’s Fire Department with upgraded facilities and increased capacity for emergency-response services. 

Constructing the station on top of a floating barge is a solution to some critical future scenarios. It will seamlessly acclimate to sea level rise and will also experience limited impact in the event of a major earthquake. Fire Station 35 is a two-story building situated on a 16,600 sq. ft. steel barge secured by four 60 in. diameter x 150 ft. long steel guide piles. This new facility has berthing areas for multiple fireboats and other rescue craft including jet skis. A Maritime Disaster Operation Center, storage of critical rescue equipment and expanded facilities for firefighters are also features of this new space. The existing dilapidated Piers 22½ and 24 have been demolished and installation of the new 96 ft. x 173 ft. steel barge will consist of driving guide piles and connecting to the vehicle access ramp.  The vehicle ramp is 16 ft. wide and will bridge the 90 ft. gap between land and float along with a new pier structure that is primarily for the public’s enjoyment of the waterfront and bay views.

Outfitting of the steel barge and construction of the building are taking place on Treasure Island; a location that offers access for crews and equipment.  Once complete, tugboats will push the floating building to its final location at Pier 22½ in which on-site construction will be minimal.
