Construction of a trench at Technoparc Montréal

Nature of the work

In the Technoparc area, the REM will gradually go underground to the north of Alexander-Fleming Street in order to avoid the wetlands to the south. The construction of a trench will create a transition towards the tunnel that will be excavated in the bedrock to connect the Technoparc and the airport. 

The work sequence includes the construction of retaining walls, soil excavation and steel framing work (the sequence below may vary).  

Impact and mitigation measures  

• Noise, dust and vibrations (planned mitigation measures)

• A noise barrier will be installed to minimize the impact of noise on workers in the area and on the children of the Innovation daycare, and sound level will be monitored
