Langan performed a geotechnical investigation and a probabilistic seismic hazard analysis for the AT&T Park baseball stadium. The stadium includes a playing field, seating area for 42,000 people, and stadium support facilities. The site, originally part of San Francisco Bay, was reclaimed by a series of fills that occurred between 1860 and the 1920s. Our engineers developed earthquake design criteria and participated in development of the environmental impact report. We also assisted with the structural evaluation of the existing 900-foot-long, 50-foot-high bulkhead retaining structure along China Basin Channel.
