As the earliest realization of the separation of landsidc and airside components,

Dulles became an archłtectural and functional model for much subsequent airport design after its completion in 1962.

The current expansion of the landmark Main Terminal building, designed by Eero Saarinen in the late 1950s, increases the annual passenger handling capacity from 12 million to 50 million passengers.

The catenary roof structure and podium are be replicated to the east and west, housing ticketing, check-in, baggage claim and support funcdons. The expansion of below-ground facilities for baggage handling, security, and passenger transport to airside under the apron minimize visual impact, as well as the disruption of aircraft circulation. The project also includes the demolition and reconstruction of enplanement and deplanement ramps and the overall renovation of the existing terminal.

The firm also conducted the expansion master plan rcview and designed the 1991 International Arrivals Building.
