A large green roof in Washington, D.C., and one of the largest on the East Coast is on the new headquarters building for the U.S. Department of Transportation (DOT).
Installing a green roof on the building is part of a current movement in Washington, D.C., says Paul Elias, managing director for The JBG Cos., Chevy Chase, Md., the company that owns the building.
"The southeast Washington area is going through revitalization," Elias says. "We believed the green roof would set a good example and be good for the area."
Gordon Contractors Inc., Capitol Heights, Md., was asked to perform the green roof system installation, including roof membranes and waterproofing for the project. With previous experience, the company was prepared.
