Seismic Retrofits, Renovations and Additions

835 Market Street, Historic Renovation, San Francisco, CA

This multi-faceted project involved 1.5Msf of new construction, addition and a historic façade and dome renovation. The project opened to the public in September 2006 and includes specialty retail and entertainment facility built in and around the existing historical Emporium department store and shopping center building.The nine-story, mixed-use facility in downtown San Francisco connects to the adjacent San Francisco Shopping Centre – providing shoppers with the largest and one of the most unique shopping destinations in California.

185 Berry Street, San Francisco, CA

This project was an innovative addition to the top of the Berry Building. Project objectives were met to expand the existing three story, 216,000sf building by 150,000sf and two new stories, while causing minimal disruption to the tenant, bio-science laboratories operated by University of California at San Francisco (UCSF). The two new stories were constructed on seismic isolation bearings over the roof of the existing structure, a concept that has never been implemented in any building in the U.S. The technique enabled the new construction to perform like a mass damper, which not only permitted the new space to be constructed without requiring structural upgrade, but also improved its seismic performance capability. Most importantly, it eliminated the need for a major seismic retrofit of the occupied building underneath.

120 Howard Street, San Francisco, CA

120 Howard Street was originally designed by architect Jorge DeQuesada and was completed in 1972. The original structure was a nine story 142,553sf office building. The project consists of a vertical addition of four floors of a steel frame on top of the existing concrete structure. The new addition will add 72,000sf to the existing structure and has a distinctive architecture with its vibrant red brick exterior and arched windows. The property’s location, views and virtually column-free, large floor plans make it an outstanding business location. 120 Howard Street is located along the Spear Street Corridor in the heart of San Francisco’s South Financial District.
