CONTRACT WIN Heavy lift and transport specialist Mammoet has been awarded the contract to help support Groupe Construction Pomerleau-Canam (GCPC) with the renovation of the new roof for the Olympic stadium in Montreal, Canada. The heavy-lift specialist will support demolition of the old roof and installation of the new one. GCPC is a consortium of
companies comprising Pomerleau and Groupe Canam. It was awarded the contract to replace the existing roof with a new fixed structure, which will have transparent glass to allow natural light to fill the stadium. Mammoet, with GCPC’s other
partners, will provide mobile cranes to support with the demolition of the old roof. It will then use its Mega Jack 5200 system to lift the new canopy 50 metres in the air and install it in place. The Mega Jack is a large jacking

system that uses beams loaded at ground level.
Six Mega Jack towers will be used to perform the lift. Besides the Mega Jack system, strand jacks will be used to stabilise the roof as it is raised.
Mammoet has also designed special final adjustment devices to sit on the top of each lifting tower. Taking the form of miniature
skidding tracks these allow precision positioning of the roof once it is at the required height. The roof will stay raised on the
jacking systems for a period of two months. This is to allow final installation work to happen, such as attaching with cables to the stadium’s famous 550 feet inclined tower (La Tour de Montréal). Much of this operation will be managed through Mammoet’s Canada East subsidiary, which employs close to 500 heavy lifting and transport experts across Ontario and Quebec. “We are thrilled that Mammoet
can play a key role in the renovation of this iconic stadium,” says Justin Hope, project manager at Mammoet.
