Clark To Construct Premier Project In D.C.'s NoMa Corridor

October 29, 2008

WASHINGTON, D.C. – The Trammell Crow Company has awarded Clark Construction Group, LLC, a contract to build a 12-story, Class-A office building at 90 K Street, NE. The office building is the first of four buildings planned for Trammell Crow's Sentinel Square development, which fronts K, L, and 1st streets in Washington, D.C.'s up-and-coming NoMa (North of Massachusetts Avenue) Corridor.

Designed by SmithGroup, Inc. of Washington, D.C., the exterior of the 412,000 square-foot building will consist of individually-glazed units, curtain wall, precast concrete, stainless steel metal panels, and black granite. Inside, a two-story lobby will showcase Jerusalem Gold marble from Israel, louvered millwork panels, and metal panel column covers. 90 K Street, NE, will also have 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.

In order to achieve LEED® certification from the U.S. Green Building Council, the 90 K Street, NE project team will employ numerous sustainable construction methods. Demolished asphalt, concrete, and brick knee walls will be recycled, and excess concrete and masonry waste will be taken to a sorting and recycling facility after the support of excavation is complete. The building's design also includes sustainable elements such as a high-performance curtain wall, low-flow plumbing devices, low-VOC adhesives and finishing compounds, roof pavers with a high Solar Reflectance Index, and a water cistern in the parking garage, which collects the building's graywater for irrigation of the landscaping. Throughout the construction of this project, Clark Logistics will also test a new paper collection and recycling pilot program.

Project partners include Haynes Whaley Associates, Inc., of Reston, Va., structural engineer; B&A Consulting Engineers, of Decatur, Ga., MEP consultants; Weidlinger Associates® Inc., of Washington, D.C, skin consultants; Wiles Mensch Corporation, of Reston, Va., civil engineer, and O'Doherty Group Landscape Architecture, of Annapolis, Md., landscape consultants. Clark Foundations began support of excavation this summer and the project is expected to reach substantial completion in April 2010.
