O’Hare International Airport – American Airlines GEM Facility

3D Modeling, Survey | Illinois | Back


The construction of Runway 9C-27C required the existing ground equipment maintenance (GEM) facility to be relocated to accommodate the expansion.


This newly constructed 112,000-square-foot GEM building is a state-of-the-art facility for American Airlines. The facility includes 30 maintenance work bays, a fluids distribution system, a wash facility, as well as employee offices. Kapur provided control, staking, and construction layout services for the project which was built by F.H. Paschen.
