Located in San Francisco’s Design District, 300 Kansas will be the city’s first advanced manufacturing and R&D space. The six-story facility will provide 150,000 SF of R&D space; 45,000 SF of vehicle floor space for prototyping, testing, and demonstrations; a rooftop garden; and collaboration space for employees. Langan performed a geotechnical investigation to evaluate subsurface conditions and provide recommendations related to the foundation system. We recommended a mat foundation, as well as a soldier-pile-and-lagging shoring system to retain the variable soil and bedrock and accommodate the planned overexcavation in the northern part of the site. We also observed the site preparation, excavation, and installation of the temporary shoring system.
