In the Heart of the City

A project that incorporated PSEC’s expertise with Urban Sites, and Difficult to Access Sites both, this basement required a 25 foot deep, 20,000 cubic yard excavation at a one-half acre site, completely surrounded by established businesses and development. The site, situated adjacent to two high-traffic streets near downtown San Francisco, required both complicated logistics for traffic management, and coordinating with, and accommodating different trades such as the shoring installation contractors, the soils mitigation/treatment contractors (utilizing cementitious conditioning of the bottom of the excavation), as well as structural excavation.

We performed the job on schedule and within budget.
