Abstract:
Construction of the terminal building and tower for the Dulles International Airport serving Washington, D. C., is described. The roof of the terminal building, a special feature of this protect, was constructed of precast lightweight concrete slabs on cables strung between the exterior supports. Two-foot beams were cast in place between bands of precast slabs when slabs and reinforcement were in place.
