Construction Milestone Achieved at 300 New Jersey Avenue

WASHINGTON, D.C. – The Clark Construction Group, LLC, project team building the 300 New Jersey Avenue office building in Northwest Washington reached a significant milestone recently as the project was topped out, meaning all significant structural work on the north building is complete.

The building, owned by The JBG Companies of Chevy Chase, Md., connects with the existing Acacia Building. The 10-story, 270,000 square-foot building is accented by a complex atrium that will connect the new building with the existing structures. Rising nine stories, the glass-capped atrium features pedestrian glass walkways connecting the buildings on various floors and is braced by a stunning steel structure supported by platforms and bridges. 300 New Jersey Avenue will also feature floor-to-ceiling curtainwalls and a six-story parking garage.

Reaching 60 feet below grade for the parking garage required one of the deepest and most complicated excavations completed by Clark Construction in the Mid-Atlantic Region.

300 New Jersey Avenue is one of the first commercial office buildings designed by renowned British architect Lord Richard Rogers of Rogers Stirk Harbour + Partners to be built in the United States. HKS of Dallas is the architect of record for this project. Additional team members include TOLK of Fairfax, Va., MEP engineer; SK&A of Rockville, Md., structural engineer; ParkerRodriguez of Alexandria, Va., landscape architect; and Wiles Mensch of Reston, Va., civil engineer. The project is scheduled to be completed in Spring 2009.
