This new 78,000-square-foot aircraft maintenance hangar replaced the existing 45-year-old maintenance hangar at the Bangor International Airport in Bangor, Maine. The project comprises a long-span aircraft maintenance bay, general-purpose maintenance shops, a second floor administration area and building utility spaces.
The project is certified LEED Silver under the U.S. Green Building Council Version 2.2 Guidelines.

The site is at the northwest corner of the existing light duty apron, east of the existing T9 hush house and west of the existing parking area west of the existing hangar. Demolition included removal of existing pavements, foundations and utilities and deconstruction and removal of the existing hangar after new construction was complete. Site improvements included new utilities, new apron, drainage improvements, fencing, drives, parking lots and associated landscaping.
The pre-engineered metal building structural system of the hangar bay is long-span steel truss frames or deep plate girder frames. The pre-engineered metal building system of the adjoining shops and administration areas is standard plate girder frames with light-gage Z purlins to support the roof. The structure is supported on shallow foundations. Exterior walls are constructed of vertical and horizontal pre-finished insulated metal panels, translucent panels, brick veneer and exposed concrete stem wall. The composite roofing system is a pre-finished structural standing seam metal roof over rigid insulation on a pre-finished metal liner panel. Horizontal sliding doors with individually operated leaves and a separate tail door allow aircraft access.
The hangar is protected by an overhead pre-action fire sprinkler system and a supplemental low-level high expansion foam system with dedicated releasing panel. All other areas of the building are protected by a hydraulically designed wet-pipe automatic sprinkler system.
