TBM Arrives for REM Project in Montreal
The tunnel will connect Technoparc station and Trudeau airport. The REM’s route will be underground in this area to protect the wetlands of the Technoparc and pass under the airport runways, more than 30 m below the surface.
Given the size of the 7.38-m diameter machine, it had to be delivered in pieces, requiring about 60 trucks. The next step is to assemble and test this specialized equipment, then drilling will begin in the coming months. The TBM will install segmental lining – 1,800 rings in total (seven piece rings).
The project is being built under an EPC contract by Groupe NouvLR, comprising SNC Lavalin Grands Projets Inc., Dragados Canada Inc., Groupe Aecon Québec Ltée, Pomerleau Inc. and EBC Inc. with participation from SNC Lavalin Inc. and Aecom Consultants Inc.
