Located in Southwest, D.C., Clark demolished the existing 254,000 square-foot building and is constructing a 12-story office building with three levels of below-grade parking.
The 471,500 square-foot structure will have a precast, aluminum, and glass curtain wall façade. The lobby will feature a two-story atrium with wood paneling, back painted glass panels, and marble flooring finishes. The building will be complete with a glass and metal canopy featuring LED lights that will illuminate the D Street entrance.
The 500 D Street, SW project is scheduled to achieve LEED Gold certification upon completion and will boast a 16,500 square-foot green roof.
Clark Concrete and Clark Foundations are a part of the project team, and will perform support of excavation and cast-in-place concrete work.
