Building 12 at Pier 70 in San Francisco has a long history that continues evolving. The building was originally constructed in 1941 and was used by Bethlehem Steel for shipbuilding in World War II. The building continued to be utilized for the construction of ships after the war and later was used to build the Bay Area Rapid Transit (BART) tunnels that cross under the San Francisco Bay. Unfortunately, in the recent past, the building has been essentially abandoned and fallen into disrepair until this project came to rescue it (Figure 1).
