Terminal 1 Expansion | O’Hare International Airport
The South Addition to the United Airlines Terminal 1 Complex was developed in response to the Transportation Security Administration’s (TSA) need to incorporate an additional security checkpoint at the south end of the Ticketing Pavilion and improve passenger circulation.
The 16,000 square foot South Addition features a new security hall with additional security checkpoints and expanded queuing space to improve service for United Airlines passengers using Terminal One (T1) and Terminal Two (T2). The new checkpoint serves the existing gates at the south end of Concourse B and offers an additional point of entry to the gates at Concourses E and F via the T1-T2 Link.
The addition features column-free, flexible space, which readily accommodates the security equipment, queuing space, and search areas necessary to meet United Airlines’ long-term needs. The design of this element also extends the architectural themes of the original building: the celebration of the structural system seen in the exposed bundled steel pipe columns and steel roof frame; the ribbons of skylights that extend at right angles from the vaulted concourse structure and suffuse the space below with natural light; and the floor to ceiling glass wall that offers travelers an unobstructed view of the airfield to the south.
