Gowen Field
C-130 Aircraft Hangar

Challenge

The Idaho Air National Guard required a modern hangar facility to support its fleet of C-130 aircraft at Gowen Field in Boise. The challenge was to design a large-span structure capable of meeting rigorous FAA, military, and security standards — while integrating maintenance, operations, and administrative support spaces within a single highly functional building. The seasonal climate conditions of the region and the specialized equipment requirements of military aviation added further technical demands to an already complex project type.

Solution

A pre-engineered metal building with expansive clear-span bays provides sufficient floor area to house multiple C-130 aircraft simultaneously. The layout separates dedicated maintenance areas, parts storage, and administrative offices to streamline operations and support mission workflows. Reinforced structural systems, heavy-duty hangar doors engineered for operational reliability, and weather-resistant detailing ensure continuous functionality under demanding conditions. Mechanical and electrical systems were coordinated to support specialized aviation equipment and safety requirements throughout the facility.

Result

A state-of-the-art hangar facility providing the Idaho Air National Guard with the infrastructure required for mission readiness and operational efficiency. The clear-span bays, integrated maintenance and support spaces, and security-compliant design position the building as a long-term operational asset at Gowen Field — a cornerstone of the Guard's aviation infrastructure in Idaho.
