Foundry Square Building I is a concrete high-rise 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 topped by an undulating standing seam metal roof supported by structural steel. The project is the 3rd of 4 planned office buildings that will occupy each of the corners of First and Howard streets in San Francisco.
Webcor overcame the challenge of integrating 8 different skin systems—including a point-suppored glass wall—to achieve the project’s aesthetic goal and to ensure a watertight, energy efficient result. Construction of the building’s concrete foundation—2 levels below grade and within the water table—required the mitigation of tidal waters with 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 the 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. Sustainable features include a unique double-glass curtain wall and raised access flooring for greater temperature control and energy efficiency.
Foundry Square Building I received a Best of 2008 Award of Merit in the New Office category from California Construction magazine.
