O'Hare International Airport
Described by the Chicago Tribune as O'Hare's "Crown Jewel," the 21-gate international Terminal 5 is organized around three primary levels: the upper level departure hall for enplaning functions including ticketing, security checkpoints, concessions, departure holdrooms, lounges and airline offices; the lower level, which contains arrival functions including the Federal Inspection Services and waiting areas; and an intermediate apron level, which contains the Automated Transit System (ATS) station and airline support services such as baggage processing. A fourth level containing administrative and mechanical services is located on a mezzanine above the upper level.
The terminal has several points of access via an upper-level roadway for passenger drop-offs and pick-ups, a pedestrian bridge from the parking lot and the ATS providing access from domestic terminals and remote parking facilities.
The departure hall is filled with natural light from an exposed structural steel truss system enclosed by expansive glazed sidewalls. Leaving the hall, passengers enter the galleria, which guides them to airline departure gates. Retail stores and restaurant/concession facilities line the galleria leading to the security checkpoints and concourses. The abundant use of exterior views provides a continuous sense of orientation facilitating efficient movement through the terminal.
