Balfour Beatty's Mid-Atlantic team provided design-build services for the new National Science Foundation (NSF) Headquarters, located at the Hoffman Town Center in Alexandria, VA. The Class-A, 759,111-square-foot office and retail building consist of two wings adjoined by a 14-story tower. The east and west wings are over 14 and 19 stories respectively, and include retail space on the ground floor and three-levels of below-grade parking. The new facility houses roughly 2,200 NSF employees and contractors and features 36 conference rooms. Amenities include a fitness center, 380-space parking garage and a large cafeteria. The project was designed for LEED Silver certification and was constructed adjacent to elevated WMATA metro tracks.

Prior to construction, 74,300-cubic-yards of earth was excavated for the garage. Of the excavated dirt, 56,000-cubic-yards were contaminated with petroleum products and on-site training was provided to ensure safe handling of the contaminated soils.
