Clark Completes U.S. Institute of Peace Headquarters

WASHINGTON, D.C. – Clark Construction Group, LLC, reached substantial completion on the U.S. Institute of Peace Headquarters project. Built on one of the last available sites at the northwest corner of the National Mall, the building is notable for its eye-catching design and high-quality craftsmanship. 

The five-story, 150,000 square-foot concrete structure was designed with three distinct wings flanking two atria. A five-story curtain wall system at the front of one of the atria creates a grand hall. The top three stories of the Institute's headquarters contain office space for the organization's staff. Each individual office has an exterior window or an interior window overlooking an atrium below. Additional building facilities include a 230-seat theater, seven conference rooms, a 2,000 square-foot outdoor terrace, a two-level underground parking garage, and a landscaped exterior plaza with curving retaining walls. 

One of the project's most notable aspects is its roof. The building's two curving roofs are designed to evoke the image of the wings of a dove. From the exterior, they appear white during the day and glow from soft light within at night. The roofs are constructed of a steel frame and nearly 1,500 white translucent glass panels. The south roof has a 12,000 square-foot surface area and spans 80 feet between buildings; the north roof has a 7,500 square-foot surface area and spans 55 feet. One of the south roof's "wings" extends 40 feet away from the building toward the nearby Lincoln Memorial.
