Thompson Builders Wraps $10.4 million Torpedo Building and Pier E-2 Work on Yerba Buena Island

Thompson Builders has completed a $10.4 million US Army Torpedo Building and Pier E-2 Improvements project on Yerba Buena Island, the company said. The work covered waterproofing and rehabilitation of the historic Torpedo Building and construction of a new public parking lot and utilities for Pier E-2, delivered under the City and County of San Francisco, EIN Presswire reported on October 22, 2026.

Inside the Torpedo Building and Pier E-2 Scope

The Torpedo Building portion focused on waterproofing and rehabilitation of the existing historic structure for the Treasure Island Development Authority, with an emphasis on preserving the building's historic character while improving its long-term durability and performance. Work included roof replacement, full building waterproofing, restoration and replacement of historic windows, exterior envelope upgrades, storefront improvements, and associated demolition and site work. The company said this portion was coordinated under TIDA oversight to ensure compliance with public works requirements, permitting regulations, and historic preservation standards.

Adjacent to the Torpedo Building, Thompson Builders completed the Pier E-2 Improvements, which provide enhanced public access and future utility infrastructure to support continued waterfront development. Scope of work included construction of a new public parking lot and associated infrastructure featuring full site grading and paving, water, sewer, and drainage utilities, site lighting, striping and signage, and installation of a restroom structure, drinking fountain, and other site amenities. Delivered as a public works project under the City and County of San Francisco, the project required close coordination with TIDA and permitting agencies, including the Bay Conservation and Development Commission, to ensure waterfront compliance.
