The client wanted to expand their three-story 300,000 sq ft office building at 185 Berry Street. The existing structure could only accommodate a one-story, 50,000 sq ft vertical addition without further retrofit. By applying base isolation technology, SGH developed an innovative solution that added two stories and 150,000 sq ft to the reinforced concrete structure. China Basin Landing is the first building in the U.S. to have a base-isolated addition on top of an existing building.
