USF Lone Mountain

Location: San Francisco
Features: Seismic retrofit and structural infill of an existing seven-story building containing dorm rooms, a ballroom, and auditorium. With the building located on the side of a hill, micropiles were installed to bedrock and new grade beams were used to reinforce the foundation as part of the retrofit. The project includes an expansion of the basement level and a structural infill of the two-story ballroom and auditorium space to create two new floors for new dorm and office space. The top four floors of dorm rooms remained fully occupied during construction.
