CFB Trenton Maintenance Hangar Development

From delivering supplies to the high Arctic to airlifting troops, equipment and humanitarian loads worldwide, 8 Wing/Canadian Forces Base (CFB) Trenton in Ontario is the hub of air mobility operations in Canada. The base is now being expanded in an effort to enhance its ability to perform routine maintenance work and home station checks on the Royal Canadian Air Force’s tactical, strategic transport and Search and Rescue aircraft. 

Canada’s Department of National Defence awarded two architectural and engineering contracts to SNC-Lavalin for the design of Maintenance Hangars 1, 2, 5 and 6 at CFB Trenton. With the goal of developing economical, suitably sized and equipped facilities, the contracts included project management and multidisciplinary engineering services (structural, mechanical, electrical and civil components). As primary consultant, SNC-Lavalin also managed the sub-consultant architect and cost estimator. 

While Maintenance Hangars 5 and 6 are still under construction, the completion of Hangars 1 and 2 is already having a tremendous impact on flight operations. Completed in May 2012, Hangar 1 now allows the Royal Canadian Air Force to maintain C-17 aircraft in Trenton in the comfort and safety of a climate-controlled building. Home station checks no longer need to be performed outside in the dead or winter. The planes also do not have to be flown to Mississippi, which had previously required air and maintenance crews to be off-site for 12 days every month. 

SNC-Lavalin is proud to be playing a role in helping the Canadian Forces maintain their fleet of aircraft so that they may continue to meet their defence challenges and carry out air operations at home, in North America and around the world. 

Hangar 1:

Maintenance Hangar 1 is a two-bay corrosion control and fuel-cell maintenance hangar that was planned and designed on a fast-track basis between 2008 and 2012. Ten stories high and the length of two Canadian football fields, the enormous hangar includes approximately 17, 500mз of concrete. That’s equal to 43%, or almost half of the above-ground concrete used in Toronto’s CN Tower.

Hangar 1 received recognition by the Canadian Institute of Steel Construction when it was awarded a 2013 Atlantic Region Steel Design Award of Excellence in the engineering category.  

Hangar 2:

Hangar 2, completed in July 2013, is being used primarily by the 436 Squadron to house and maintain its new and growing fleet of C-130J Hercules tactical transport aircraft. Under consideration for Leadership in Energy and Environmental Design (LEED®) gold level certification, Hangar 2 has several state-of-the-art green features incorporated into its design, including:

  • An electric charging station for employees with hybrid/electronic vehicles
  • Changing rooms and shower facilities for those who have adopted greener transportation methods
  • A 100 percent reduction in the use of municipally provided potable water for sewage conveyance has been achieved by rainwater harvesting
  • To reduce the building’s effect on ozone depletion, which contributes to climate change, the HVAC (heating, ventilation, and air conditioning) system has no chlorofluorocarbon (CFC) refrigerants
  • More than 75% of the waste generated during construction was diverted from landfills and instead was reused or recycled

Hangar 5:

The new four-bay Hangar 5 will serve as a first-line maintenance facility for the C-130J Hercules. It will include a wash bay, a confined space entry bay and two maintenance bays. The facility also has down-flow refinishing paints booths, complete with three state NESHAP (National Emissions Standards for Hazardous Air Pollutants) compliant exhaust filtrations, curing and humidification capabilities.

Hangar 6: 

Hangar 6, a new two-bay hangar, will provide general maintenance for first- and second-line activities. Each hangar bay will be primarily designed for maintenance of the C-17, but will have the flexibility to be used for the C-130Hs and C-130Js.
