UCSF Block 34 Clinic and Parking Structure

UCSF Block 34 Clinic and Parking Structure: This project features two new buildings for the UCSF campus in San Francisco’s Mission Bay district – a new clinic building and a parking garage to support it. The site was historically below water in a shallow bay known as Mission Bay, and in the late 1860s was reclaimed by placing fill. PSEC was the first contractor onsite to break ground, demolish the existing parking lot, remove buried structures some dating back over 100 years, and export over 10,000 tons of hazardous soil.

Yerba Buena Island Podium

Yerba Buena Island Podium: The Bristol at Yerba Buena Island was the first project to break ground of any of the new developments at Yerba Buena and Treasure Island. The project consisted of excavating and off-hauling over 37,000 cubic yards of sand cut from a native hillside, and placing the material at a location on Treasure Island. In addition, to meet the geotechnical requirements and “key” into the hillside, PSEC over-excavated and recompacted over 15,000 cubic yards of soil at the building’s subgrade.
