Regional Concourse Study

Regional Concourse Study – Large Hub Airport

The feasibility study evaluated the construction of a stand-alone Regional Concourse adjacent to the main terminal at a large hub airport. Two major elements of the conceptual design were a two-story concourse building supporting ten regional aircraft gates and an underground pedestrian tunnel to provide access to the existing Terminal.

The proposed concourse featured curved steel trusses spanning the 78-foot building width supported by large round pipe columns. A partial intermediate mezzanine level consisting of open web steel joists and steel beams was supported by wide flange columns. The selection of pile foundations and a structured ground floor slab was driven by poor soil conditions at the site.

The cast-in-place concrete pedestrian tunnel, located 5 feet below the tarmac, was designed for the anticipated gravity and lateral loads imposed by vehicular traffic, soil, and water pressures. The tunnel was founded on a concrete mat and piles.

• Size: Concourse – 26,000 SF; Tunnel – 17,500 SF
