A consortium of Montreal companies led by Pomerleau and Canam Group has won a US$542m contract to replace the fragile roof of the city’s Olympic Stadium.

At present, the stadium cannot be used for half the year because of the roof’s fragility, since events are cancelled if more than three centimetres of snow are forecast.

Groupe Construction Pomerleau-Canam (GCPC), as the consortium is called, will also be tasked with maintaining the roof for the next 10 years.

The plan is to replace the present cover with a fixed, rigid structure with a transparent glass hoop. The concrete technical ring will be replaced by a steel tube with curved cladding to match the stadium’s architecture.

The work will be done in three phases and is expected to take four years to complete, starting this summer.

The project was considered the cheaper option than demolishing the structure, which was expected to cost  US$1.5bn. The decision was to replace the unstable and hazardous roof of the 1976 venue.

Philippe Adam, Pomerleau’s chief executive, said: “The project involves a high level of technical complexity and generates a certain amount of enthusiasm from the general public.”

Other companies in the consortium include Walter P Moore, Enclos Tensile Structures, Lemay and ACDF Architectes.
