Seeking to maximize the usable length of each terminal, the airport was designed as a series of semi-circular arcs. This allowed the gates to be spaced close together on the interior while providing adequate clearances for airplanes on the exterior. The design and construction were made economical by using repetitive precast concrete members that could be fabricated and erected efficiently at each of the arc segments.
