In a Joint Venture with James G. Davis Construction, Gilford led the site work efforts for the construction of a new 31-story office tower in Tysons Corner, Virginia. Completed in 2018, the new 470-foot tower (940,550 sf) is second tallest structure in the Washington metropolitan area behind only the Washington Monument.
The 26-acre Capital One campus is generally bounded by the Beltway, Route 123 Chain Bridge Road, and Scotts Crossing Road. At the start of construction, site development included a 14-story office building (479,000 sf), conference facility, and parking garage (9 levels). The Metro McLean Silver Line station is nearby. In addition to the newly completed office tower, plans for future site development include residential towers, hotels, additional office buildings, and other structures. Upon completion, the campus will encompass approximately 5.26 million square feet.
Gilford’s site work component included installation of site utilities, realignment of Capital One Drive, and construction of a multi-level parking structure.
Site infrastructure encompassed relocation of existing and installation of new public main utilities (electrical ductbanks, gas, storm water, sanitary sewer, domestic water, and communications). Utility sub-ins were provided for planned future site development.
Realignment of Capital One Drive encompassed construction of a 2,000 linear foot road with entrances onto Route 123 Dolley Madison Boulevard and Scotts Crossing Road. Challenges included maintaining existing roads and traffic control on an active business campus, sustaining underground utility functions, and coordinating with WMATA for the new Metro Silver Line Tysons Corner Station.
Parking Structure: Sitework encompassed construction of a six-level parking structure (three levels below grade and three levels above) with provisions for a future hotel on a portion of the structure.
Base Building: Under a subsequent contract, the Davis/Gilford team constructed the 31-story base building. Work included erecting support for the excavation, removal of approximately 250,000 yards of soil, drilling 1,200 auger cast-in-place piles for the foundation, and placing approximately 100,000 yards of concrete.
