Quality & Sustainability Highlight Completed 90 K Street
WASHINGTON, D.C. – Clark Construction Group, LLC, has completed work at 90 K Street NE, building a 12-story Class-A office building for developer and owner Trammell Crow Company that delivers quality and sustainability. 90 K Street is the first of four buildings planned for Trammell Crow Company's Sentinel Square development, which fronts K, L, and 1st Streets in the city's NoMa (North of Massachusetts Avenue) neighborhood.
Designed by SmithGroup, Inc. of Washington, D.C., the exterior of the 412,000 square-foot building consists of individually-glazed units, curtain wall, precast concrete, stainless steel metal panels, and black granite. Inside, a two-story lobby is finished with Jerusalem Gold marble, louvered millwork panels, and metal panel column covers. 90 K Street also has three below-grade levels with 317 parking spaces. A shared courtyard and landscaping, including granite tree planters, flower beds, decorative metal railings, and an irrigation system, will unify this building with the three additional buildings to be developed at Sentinel Square.
90 K Street anticipates earning LEED® Gold certification from the U.S. Green Building Council. Among the project's many sustainable elements are low-emitting materials, low-flow water fixtures, roof pavers with a high Solar Reflective Index, and a high-performance curtain wall system. A water cistern in the parking garage collects the building's graywater for irrigating the landscaping.
