San Francisco General Hospital

San Francisco General Hospital and Trauma Center located between 22nd and 23rd Streets on Potrero Avenue for the City and County of San Francisco. The 284 bed/14 operating room hospital and trauma center will provide the only Level 1 Trauma Center for residents of San Francisco and northern San Mateo County. The 448,000 sf hospital will be a steel moment frame structure on a mat foundation with base isolators. The hospital will have two (2) levels below grade and eight (8) levels above grade including a mechanical penthouse. Ties to the existing hospital will be made by means of a tunnel at the B1 level and a bridge at the 2nd floor.


Brio Engineering Associates is the Civil Engineer of record for all site work for this medical facility addition to the existing San Francisco General Hospital campus. The $850 million project is scheduled for LEED Gold Certification and is built in 4 phases. Phase I consists of site utilities relocation and replacement; Phase II consists of Service Building modifications and equipment additions; Phase III consists of excavations, foundations and structure frame; and Phase IV consists of the new Acute Building Enclosure and build out.


The new building uses base isolation and it footprint landed in the heart of the existing campus utility tunnels and infrastructure. Brio Engineering developed plans to re-route utilities within tight confines to provide continuous service to the existing operating hospital. In addition, the existing combined sewer and storm drain system had to be separated into separate storm drain and sewer infrastructure to allow for treatment of the stormwater before leaving the site.
