Three-Building Constitution Square Project Complete in NoMa
WASHINGTON, D.C. – Clark Construction Group, LLC, has completed the three-building, 1.6 million square-foot Constitution Square project in Washington, D.C.'s NoMa district. During its construction, the $530 million project ($275 hard construction cost) was the largest private construction project in the city. Developed by StonebridgeCarras and Walton Street Capital, Constitution Square includes two office buildings and a residential building, spans a full city block, and is serviced by two entrances to the New York Avenue-Florida Avenue-Galludet U Metro station.
Both of Constitution Square's office buildings are 12 stories above grade with three levels of below-grade parking. The buildings' exteriors are precast concrete with punched windows and curtain wall. The 350,000 square-foot One Constitution Square has a covered and partially enclosed roof top terrace with a panoramic view of Washington, D.C. Two Constitution Square is 589,000 square feet and features a three-story glass atrium with limestone flooring, back-lit imported onyx stone lining the walls, a massive skylight, and an interior curtain wall system.
The Department of Justice has fully leased Two Constitution Square. Clark Interiors performed the tenant fit-out of the office space.
Both Constitution Square office buildings achieved LEED® Platinum certification. In addition to sustainable features including efficient fixtures and a design that maximizes natural light, the buildings have greywater recycling systems and green roofs. In its annual "Best of" awards competition, Mid-Atlantic Construction magazine named Two Constitution Square the Best Green Office Project of the Year in 2010; One Constitution Square received an award of merit in the same category. In addition, the entire Constitution Square project earned LEED for Neighborhood Development certification through a U.S. Green Building Council pilot program.
Constitution Square's 657,000 square-foot, 13-story residential building includes 440 luxury apartments, a 204-room Hilton Garden Inn hotel, and a 50,000 square-foot Harris Teeter grocery store. Building amenities include three courtyards, a fitness center, a club room, an outdoor swimming pool with sun deck, and a roof terrace.
Constitution Square is one of several recently-completed Clark projects in Washington, D.C's NoMa (North of Massachusetts Avenue) business district. Other NoMa projects include the Courtyard Marriott US Capitol, 90 K Street/Sentinel Square I, and 111 K Street, NE.
