Clark Construction Group, LLC led the Design/Build team to create the U.S. Coast Guard Headquarters Building on the St. Elizabeths West Campus in southeast Washington, D.C. The project is the first stage of the Department of Homeland Security’s consolidation and is located on a designated historic landmark in the District’s Anacostia neighborhood. When complete the first quarter in 2013, the new U.S. Coast Guard Headquarters building will feature an 11-story office building providing about a 1.2 million square feet facility for 3,860 employees, a separate central utility plant, and two seven-story parking garages. There is a 120-foot change in elevation on the 176-acre project site and the headquarters building’s design takes advantage of the natural topography. Below an entry courtyard at the site’s highest location, the building consists of linked, cascading quadrangles, clad in brick, schist stone, glass, and metal constructed into the hillside. The building’s wings, with a red brick skin, further break down the scale of the massive facility, as well as allow for greater penetration of natural daylight to internal areas. The U.S. Coast Guard Headquarters Building project is targeting LEED® Gold certification. The main facility will feature approximately 400,000 square-foot green roof and high-efficiency mechanical and electrical systems. Additionally, the construction of wet ponds, bioswales, and step pools will assist with stormwater management.
