Los Angeles U.S. Courthouse
The General Services Administration (GSA) tapped Clark to build the new United States Courthouse in downtown Los Angeles. Clark is part of the design-build team, which includes architect Skidmore, Owings & Merrill, LLP.
Clark is constructing a 10-story, 600,000 square-foot court building. Referred to as the “Cube” because of its shape, the new facility will feature 24 courtrooms and 32 justice chambers. A sky-lit central courtyard (“Light Court“) at the structure’s core will provide natural light and circulation to the building’s interior spaces. The Cube will be anchored by two levels of below-grade parking, as well as mechanical and back-of-house spaces.
The new courthouse has a unique design to address the Federal Government’s blast and setback requirements. Clark is constructing a structural frame for the "Cube" that sits back an entire bay around the first floor, providing for 36 additional feet of setback on each side of the building perimeter.
Among the facility’s sustainable elements is a combined cooling, heating, and power plant (CCHP) or “Tri-Gen” system. The electrical system will include two 5,000-Amp substations and a 2500kW diesel generator for emergency power.
The building envelope will feature a high-performance faceted curtain wall façade. This system will give the courthouse a lively expression that changes throughout the day; it also will reduce radiant heat input through the building envelope and provide ample natural light to internal courtrooms and common areas. Additionally, the project includes a 52,000 square-foot, 400 kW photovoltaic array at the roof.
The project is convertible to using biomass materials in the future so that it can one day reach net-zero energy.
