Completed projects

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.
