Southwest Maintenance Hangar
The AirTran Airways (currently Southwest Airlines) Maintenance Hangar included the construction of a hangar, auxiliary office complex, and site work located at Hartsfield-Jackson Atlanta International Airport (HJAIA). The 60,000 sf hangar was built to accommodate three (3) 717s or two (2) 737s, with construction of the hangar consisting of tilt-up concrete panels forming the hangar’s walls, while the structure itself is a pre-engineered Rubb building, the first of its kind in the Southeast. The Rubb building is a galvanized steel structure covered by a tensioned PVC-coated fabric membrane. The project involved the coordination of relocating water mains, sanitary and Colonial Pipeline fuel lines as well as the relocation of main fiber optics and other miscellaneous utilities.
The office complex consists of 20,000 sf with two (2) floors approximately 10,000 sf each. The office is a steel frame and masonry structure, with one side as a concrete demising wall that is shared with the hangar. The first floor contains work space for maintenance personnel, locker rooms, a break room, material storage space, and a loading dock. The second floor is office and meeting space for approximately 80 employees.
Site work for the new hangar included a 20-foot taxiway and apron paving section over 9 inches of soil cement. The taxiway paving included integral airfield lighting.
The hangar’s fire protection system is capable of covering the hangar floor in foam up to a height of 48 inches in less than two minutes. This is achieved through a high-expansion foam system supplied by a 180,000-gallon underground water reservoir. Other systems installed to facilitate aircraft service include a 400 Hz power converter, paint booth, composite grinding booth, a waste oil and solvent dump station, five (5) Dabico utility pits, and three (3) mobile electrical panel boards.
