Washington Dulles West Expansion and APM

Chantilly, Virginia

The HOK-designed underground automated people mover (APM) stations at Dulles connect travelers from the airport’s Main Terminal Building to Concourse B and the International Arrivals Building.

HOK planned and designed two underground International APM stations in support of the western expansion of Concourse B at Washington Dulles International Airport. One station services the Main Terminal Building; another services the International Arrivals Building.

The Concourse B expansion included a 1,040-ft. extension with passenger elevator access to the underground APM station below. This three-story structure supports building environmental systems, airline and tenant support space and operations on the lower apron level. The west and east APM nodes serve as the main access for all domestic passengers and departing international passengers.

Elevators, escalators and stairs connect passengers to the stations from the tunnel/platform level through to the concourse level. These nodes also include air supply and exhaust for the tunnel system; concession and retail spaces; airline clubs; Flight Information Display Systems (FIDS); and passenger hold room areas.
