A consolidated ground equipment maintenance center.


We provided planning, architecture, and engineering services for United Airlines’ (United) new 112,000 SF Ground Equipment Maintenance (GEM) Facility, which supports the maintenance of all of their ground equipment at O’Hare Airport. We supported the project through the coordination of design and regulatory approvals, project scheduling, and construction.

Tailoring the Solution

A flexible facility that serves the changing demands of the airport environment.

Our design consolidates the existing United and legacy Continental Airlines GEM buildings into one large-scale facility comprised of three primary areas: administrative offices, maintenance work bays, and specialized workshops.

With its greater size, the facility houses extended maintenance bays for super aircraft tractors. The building also supports specialized equipment, such as an extensive bridge crane system, a compressed air and bulk fluids system, a vehicle exhaust system, automated parts and tool storage systems, and more. The new facility offers United the flexibility to address the demands of the airport environment while servicing a wider array of equipment.
