AVA – 55 Ninth

AVA 55 Ninth is a 17-story residential building with two underground parking levels in the SOMA district. The building’s northern portion has two below grade parking levels while the remaining development has one below grade parking level. Excavations extend up to 25 feet below existing street grade. Amenities include a fitness center and a 10,000 SF courtyard. Langan performed multi-disciplinary engineering services from schematic design through construction. We worked closely with the client and design team to come up with effective and economical foundation, shoring, seismic design, and dewatering systems. The San Francisco Public Utilities Commission (SFPUC) approved our Stormwater Control Plan and the project became one of the first to comply with the City of San Francisco Stormwater Management Ordinance.
