Silvery Towers is a residential development in downtown San Jose. The project features two towers, 22 and 20 stories, above three basement levels, offering retail and residential space, including 643 apartment units and associated parking. The three basement levels required excavation of 34 to 38 feet below street grade. Langan provided multi-disciplinary engineering services for design and construction of the project. Data from the geotechnical investigation was used to reduce field exploration costs. We performed field observation and provided weekly reports regarding stormwater compliance per the Storm Water Pollution Prevention Program (SWPPP).
