CFB Trenton Maintenance and Operations Hangar

Project Overview

Located on the north airfield at Canadian Forces Base Trenton in Ontario, this maintenance and operations hangar was delivered to support ongoing expansion and operational readiness at one of Canada’s primary air mobility hubs. The facility is purpose-built to accommodate second-line maintenance for the CC-130J Super Hercules aircraft, providing a controlled environment where aircraft servicing, inspection, and support functions can be carried out efficiently.

The project includes a two-bay hangar totalling approximately 125,000 square feet, alongside 50,000 square feet of integrated office and shop support space. Together, these elements form a cohesive operational environment that supports both technical maintenance activities and the administrative functions required to sustain them.

Design and Construction

The structure is defined by long-span construction with the hangar doors alone measuring 59 feet high and 184 feet long. This configuration provides the clearances and flexibility required to accommodate large aircraft and associated maintenance equipment, while enabling efficient movement within the space.

The building envelope incorporates architectural aluminum panels, curtain wall systems, spandrel glass, and masonry, supported by a thermoplastic polyolefin roofing system. Material selection and detailing were aligned with durability requirements and long-term performance expectations typical of airfield operations.

Operational Environment

Designed as a specialized operational facility, the hangar integrates maintenance bays, support shops, and administrative areas within a single footprint. This allows for streamlined workflows between aircraft servicing, technical support, and coordination functions, minimizing operational friction and improving overall efficiency.

Located within an active airfield environment, the project required careful coordination of construction activities alongside ongoing base operations. Work was sequenced to maintain uninterrupted access and ensure compatibility with existing infrastructure and operational requirements.

Outcome

The completed facility provides a dedicated, purpose-built environment that supports the ongoing maintenance and readiness of critical air assets. By aligning building design with operational needs and integrating supporting spaces within a unified layout, the project contributes to the long-term functionality and resilience of CFB Trenton’s air operations.
