FOUNDRY SQUARE BUILDING 1, SAN FRANCISCO, CA

Foundry Square Building 1 consists of a concrete structure with 10 floors of office space, and two levels of subterranean parking. The structure's 11th floor consists of 11,637 sq ft of mechanical space and is topped by an undulating metal roof, supported by structural steel. The project includes a unique double-glass curtainwall and raised access flooring for greater temperature control and energy efficiency.

Webcor overcame the challenge of integrating 8 different skin systems to achieve the aesthetic goal of the project while ensuring a watertight final product. The point-supported glass wall and undulating standing seam metal roof are other unique aspects of the building's design. Construction of the concrete foundation system- 2 levels below grade and within the water table- required the mitigation of tidal waters through 24/7 dewatering of the site.

To meet the tenant's requirement for large, contiguous spaces, the design was adjusted by using 30' x 30' structural columns to achieve floor-to-floor heights of 14 feet. Building Information Modeling was used to coordinate all MEPS and project was completed ahead of schedule and under budget.

Although LEED certification was not sought, the project has many sustainable elements and would likely qualify for a silver or gold rating.

Key sustainable building features:
  • High-performance facade controls temperature changes by more than 17.5% over baseline
  • Raised access flooring reduces energy consumption by up to 15%
  • Natural light and views to the exterior from over 90% of interior spaces
  • Non-ozone depleting refrigerant system
  • Use of healthy indoor air quality methods
  • 75% of construction waste diverted from disposal
  • Continuous exchange of fresh air and filtered air during construction
Foundry Square Building 1 received an Award of Merit in the Office category California Construction's Best of 2008 Awards.
