Mammoet has secured a contract to support Groupe Construction Pomerleau-Canam (GCPC) in replacing the roof of Montreal’s Olympic Stadium. GCPC, a consortium of Pomerleau and Canam Group, will install a new fixed roof with transparent glass panels, allowing natural light to illuminate the stadium.
Mammoet will play a critical role by providing mobile cranes for the demolition of the existing structure and executing a complex lifting operation to install the new canopy. The project will be managed through Mammoet’s Canada East subsidiary, which employs nearly 500 heavy lifting and transport specialists in Ontario and Quebec.
A key phase of the project involves constructing the new roof inside the stadium on temporary supports. Once completed, Mammoet’s Mega Jack 5200 system will lift the structure 50 meters into place. Using six Mega Jack towers, this advanced system will raise the heavy structure efficiently and safely. Strand jacks will provide additional stability during the lift.
To ensure precision placement, Mammoet has designed custom adjustment devices on top of the lifting towers. These miniature skidding tracks will fine-tune the roof’s final positioning.
The roof will remain elevated for two months to allow for final attachment, including cable connections to the stadium’s iconic 550-foot inclined tower, La Tour de Montréal.
