Renovation and Seismic Rehabilitation of Pier 1 Port of San Francisco, California

At the heart of San Francisco's historic waterfront, Pier 1 was substantially rebuilt and refurbished. Built as a warehouse during an era of expansion and renovation along the San Francisco waterfront, and now listed on the National Register of Historic Places, Pier 1 is a remarkable example of characteristic San Francisco waterfront architecture and pier waterfront construction. The project required a seismic retrofit of the structure. This paper presents the renovation strategy which preserved much of Pier 1's industrial character through the careful insertion of steel-framed mezzanines, and the non-intrusive addition of large diameter steel piles into the deck structure to resist seismic loads.
