Southwest Airlines Maintenance Hangar

Butler Heavy Structures designed and supplied the structural steel and cladding systems for this new 80,000 sq. ft. maintenance hangar for Southwest Airlines located at Dallas Love Field Airport.

A unique framing system was required to meet the Owner’s requirement for a two-bay opening on the front of the hangar and a one-bay opening on the side of the hangar to accommodate three Boeing 737-700 Next Generation series aircraft.

The framing system consists of a 22′ deep parallel chord truss spanning 275′ across the front of the hangar. 12′-6″ deep parallel chord trusses spanning 158′ and spaced at 27′ centers span from the front truss to the back wall of the hangar. 9′ deep non-parallel chord trusses spanning 138’ provide the clear opening in the sidewall of the hangar for the third maintenance bay.

Roof trusses support maintenance crane runways. A two-story office/maintenance shop is provided along the back wall of the hangar. The entire facility features a standing seam metal roof system and metal wall panel system.
