The San Francisco 49ers Stadium is a 68,500-seat, open-air NFL stadium with an elevated pedestrian walkway at plaza level, retaining walls, interior and exterior concrete masonry unit walls, mechanical and electrical equipment pads, and three pedestrian bridges across the San Tomas Aquino Creek. Langan developed geotechnical, foundation, and seismic design criteria, including site-specific response spectra, for the project. We observed geotechnical aspects during the stadium's construction. Langan took a creative approach to solving issues as they arose and consulted on an alternative foundation system of more than 3,000 drilled displacement piles. This system proved to be cost-effective and was successfully completed within the aggressive construction schedule.
