REM de l’Est

Global description

This project concerns the monitoring of the noise emitted by the operations of the tunnel boring machine, the construction work of the stations and the viaduct of the REM de l’Est works in Montreal. Atelier 7hz has prepared an expert opinion on the noise induced by this work, on two construction sites and for different phases of the project, in order to determine the feasible measures to minimize the impacts and identify the follow-up measures required.


Many residences are present in the immediate vicinity of the works. An assessment of sound levels was carried out for the two construction sites and the different phases of work. In the event of foreseeable exceedances of the regulatory thresholds, sound attenuation measures have been recommended.
