The STM, principal contractor and project manager of the Blue line extension, launched today a pre-qualification notice for the construction of the tunnel of the blue line metro extension.

“This will be the first use of a TBM in the long history of the STM,” says Marie-Claude Léonard, Interim CEO of the STM. “It will allow us to speed up the excavation process and will help us to build high-quality infrastructure as we extend the Blue line of the Montréal métro.”

“The publication of the pre-qualification notice is great news for the STM and represents another step toward the execution phase of this structuring project for the STM, its clients and citizens of the East.” added Éric- Alan Caldwell, Chair of the STM Board of Directors.
