United Club Expansion | Gate C10

Located in O’Hare International Airport‘s Terminal 1 between Gate C10 and C16, the new 17,000 sf United Club has seating for over 400 guests, dedicated wellness rooms, a full kitchen and buffet, and self-scan e-gates for entry. The project was the first significant structural addition to T1 since being built in the 1980s and included relocating a fuel main on the west side of the concourse and new hydrant fueling pits. Coordination with multiple stakeholders and regulatory organizations, including United, CDA, TSA, and FAA, was needed to ensure construction work could be completed securely.

As part of the project management team, Cotter provided a construction engineer for the two construction project components – a new construction core and shell package (including caissons) and the interior design of the new lounge. In addition, the Cotter team provided contract administration, permitting, submittal oversight, coordination of drawings, and the process for FAA form 7460. Cotter also managed submittals, RFI’s, procurement and assisted in coordination between MEP trades based on team-developed BIM modeling and clash detection working groups.

Project Team

Constructing a building in the middle of one of the world's busiest airports presented a unique set of challenges. From coordinating with multiple stakeholders and contending with strict security protocols to ensuring the safety of workers and passengers alike, every step of the process required careful planning and execution. It was only through a collaborative and adaptable approach that we were able to turn this project into a reality.
