Rockridge Geotechnical, Inc. (RG) provided geotechnical engineering services for this building jointly developed by BRIDGE Housing and Berkeley Food & Housing Project (BFHP). RG performed a geotechnical investigation for the project and consulted with the development and design teams from the early stages of the project through entitlement, schematic design, and design development. Throughout schematic design and value engineering, RG addressed the geotechnical implications for constructing a building with one or two subterranean parking levels, as well as a building that will be constructed at-grade.

The building constructed is six stories tall and constructed at-grade with courtyards and open spaces to the front and rear. BRIDGE and BFHP spaces are separated by a demising wall and have separate vertical circulation systems (i.e., exit stairs and elevators) on each side of the demising wall. On the BRIDGE side, there will be affordable residential rental housing for families, as well as shared community amenities such as community rooms. On the BFHP side, there will be emergency homeless shelter rooms, transitional housing rooms, studios for permanent supportive housing, supportive services, administrative offices, a reception area, conference rooms, computer rooms, community and multipurpose space, a commercial kitchen, storage space, laundry, and flexible spaces.

The building is supported on a mat foundation, except the northeastern corner of the building is located within the Bay Area Rapid Transit (BART) zone-of- influence (ZOI) and is supported on drilled piers installed inside an isolation casing to prevent surcharge on the BART substructure. RG also provided geotechnical observation and testing services during the construction of the project.
