Platform 16

Platform 16 is a 1.2 million SF office campus development consisting of two six-story buildings (Buildings A and B) connected by a shared basement and a third building (Building C) constructed at grade. Langan prepared a geotechnical investigation report, reviewed shoring plans and structural plans, evaluated the subsurface conditions and potential seismic hazards, and provided recommendations for the foundation and other geotechnical aspects. We concluded Buildings A and B can be supported on a mat foundation and recommended that Building C is supported by a deep foundation system consisting of Auger Cast Displacement Piles. We are currently providing observation and testing during site preparation, grading, placement and compaction of fill, installation of building foundations, shoring and underpinning, and testing of tiebacks and tiedowns.
