U.S. Capitol Visitor Center

The ninth, and largest, addition to the U.S. Capitol in Washington, DC, encompasses 580,000 sq. ft. on three below-grade levels, and includes 170,000 sq. ft. of expansion space for the House and Senate. Its five acre footprint is larger than the Capitol’s current footprint.

The project was conceived because the Capitol itself has inadequate restrooms, stairways, elevators and other facilities to handle a large volume of visitors. The Capitol Visitor Center accommodates 12,000 people a day, and up to 4,000 at one time. It features a 600-person dining facility, 2 25-passenger elevators, 26 restrooms and two orientation theaters where visitors view an introductory film before beginning their tour. VDA provided full consulting services for twenty (2) 2- & 3-stop hydraulic elevators, four (4) 7-stop traction elevators, and six (6) escalators

The $621 million project opened to the public in December 2008.
