STM Works


May 2020 – Worksite reopenings

Our worksites will begin gradually reopening on May 11. Our top priority remains ensuring the safety of all, while complying with the recommendations made by public health authorities and the CNESST. Planned preventive health measures include adapted work protocols, improved sanitary facilities, and redesigned rest areas.

Did you know that...

When a construction site requires the use of explosives near the métro network, a procedure to check structural integrity is systematically used.

First, a seismograph records measurements taken inside the tunnels on a continuous basis. Then, after every detonation, inspectors specialized in structural engineering walk through to carefully inspect the tunnel walls.

This means that service interruptions lasting a few minutes are required for the inspectors to complete their work and ensure the network’s longevity and overall safety.

Thankfully, these preventive measures usually take place during off-peak hours and are conducted over very short periods of time.
