Complete Decommissioning and Dismantlement of the Mirabel Airport
Project Overview
Delsan-A.I.M. was contracted by Aéroports de Montréal (ADM) to manage the complete decommissioning and dismantling of the former Mirabel Airport, located north of Montréal. As the general contractor, Delsan-A.I.M. coordinated with multiple trades to prepare for demolition, including the disconnection, relocation, and capping of electrical, mechanical, and communication services.
Scope of Work
The project focused on two major structures:
  • Terminal Building: A five-level reinforced concrete and steel-framed structure with a footprint of 348,000 ft² and a height of 75 ft.
  • Parking Garage: A three-level reinforced concrete structure with a footprint of 332,000 ft².
The decommissioning work involved large-scale abatement of hazardous materials, including:
  • 6,800 tonnes of asbestos-containing materials.
  • Polychlorinated biphenyls (PCBs) from light ballasts.
  • Mercury-containing fluorescent light tubes.
  • Residual oils and ozone-depleting substances.

Execution
Decommissioning Activities
A crew of approximately 100 laborers systematically removed hazardous materials, working level by level using both manual and mechanical methods under high-risk protocols.

Demolition
Once decommissioning was complete, large excavators equipped with specialized tools, including shears, pulverizers, hammers, magnets, and grapples, were deployed to dismantle the structures. A high-reach excavator was used for the terminal building.

Material Processing
  • Debris Management: Over 55,000 tonnes of demolition debris were shipped off-site.
  • Concrete Recycling: 135,000 tonnes of concrete were processed on-site using a mobile crusher and stockpiled for future use by the owner.

Project Success
Delsan-A.I.M. safely and efficiently completed the project through meticulous planning and execution. The team overcame technical challenges, such as controlling dust and debris to prevent disruption to neighboring airplane manufacturing facilities and active runways. This high-profile project demonstrated Delsan-A.I.M.'s expertise in large-scale demolition and environmental responsibility.
