Bomber Agile Common Hangar (BACH)

LDG led the architectural and mechanical engineering efforts and provided electrical engineering expertise for the construction of a 196,791-SF high-bay depot maintenance hangar. This pre-engineered metal building (PEMB) facility consists of a 139,256 SF hangar bay, a 16,381 SF one-story shop area to the north, and a 41,154 SF two-story shop/administrative space to the south. The BACH is a mission-critical facility for the depot maintenance of B-52 and B-21 Bomber aircraft.

The design accommodates up to four large bombers and various airframe types, with maintenance docks equipped for multiple airframes and fiberglass panels for natural lighting. Constructed with structural steel, the facility features structural insulated wall panels, a standing seam metal roof, and heavy-duty overhead doors. Windows and entrances are thermally broken aluminum, with weatherproofing louvers and soffits for durability.

The hangar features standing seam metal roofing on rigid insulation, supported by steel beams and custom trusses. The walls consist of insulated metal panels on steel girts. Special features include a five-ton bridge crane and four two-ton roof-supported monorail hoists.

The shop and admin space has standing seam metal roofing, insulated concrete sandwich panels with a thin-brick veneer, and a FEMA storm shelter. It also includes a two-ton bridge crane in the Landing Gear Shop, supported by the roof structure.

Benefits
•  Pre-Cast and SIPs allow for speed of enclosure reducing construction time
•  Segmental hangar bay units allow to add/reduce hangar area without effecting admin and maintenance functions

Discoveries
•  This prototype hangar is the first of its kind
•  This ACM can be used in temporary and permanent construction techniques
•  Expedited construction for war ready
