The National Historic Landmark at 50 United Nations Plaza in San Francisco is a Beaux Arts building and a contributing resource to the larger San Francisco Civic Center Historic District. The original architect, Arthur Brown, Jr. also designed the San Francisco City Hall, Opera House and Coit Tower. The overall vision for this project was to create energy-efficient office space and a modern, comfortable working environment for federal workers in this historically significant building. The U.S. General Services Administration retained the services of Interactive Resources to perform a comprehensive Program Development Study for the alterations and renovation of the federal building, which served as the intended scope of work for the architect-engineer design team and the basis for the necessary funding request through the American Recovery and Reinvestment act of 2009 from Congress.
Building systems and components were replaced to meet current GSA standards utilizing sustainable design principals and achieving LEED Platinum Standards for new construction (NC). The project included a major seismic structural upgrade, refurbishment of historic exterior windows, blast protection, and restoration of the exterior stone. A complete realignment of the interior was included along with a new HVAC system, energy efficient lighting, upgraded electrical distribution system, improved security, upgraded fire protection system and restoration of historically significant interiors. Historic preservation played a fundamental role in the development of the report as all proposed design aspects have to work with the historic nature of the building.
