Rielle mechanical ventilation station

Preparatory work will take place in the parking lot between 252 and 290 Gordon Street.

Bell overhead cable relocation:

• Bell will remove its existing lines from the worksite and maintain service with a temporary bypass. All communications about this will be handled by Bell.

The expansion and upgrading work will result in the following improvements:

• The MVS will be much quieter thanks to more powerful noise suppressors. It will comply with all Verdun Borough noise by-laws.
• With its clay brick exterior, the building will blend in seamlessly with the surrounding architecture.
• The landscaping will cover more space and have a more diverse range of plants.
• The green spaces and permeable pavers will provide eco-friendly water management by allowing rain to drain into the ground.
• Tunnel ventilation will be more powerful and efficient.

The project will involve pile driving and soil and rock excavation.

• We’ll update this page with the excavation method once it’s been chosen. Micro-blasting will not be used.
• The excavation may generate vibrations big enough to be noticed by residents living near the worksite. That’s why we’re requiring the contractor to hire a specialized firm to conduct inspections (including taking photos) of buildings in the area. These inspections will document the condition of the buildings before and after the work. Property owners affected will be notified accordingly.
• The firm hired by the contractor will also have to monitor the vibrations generated by the work using a device called a geophone. This is intended as a preventive measure. Data will be collected and analyzed in real time to ensure compliance with vibration limits.

In accordance with municipal by-laws:

• The work will mainly be scheduled on weekdays between 7 a.m. and 7 p.m. To keep the project on schedule, some work may occasionally continue on weekends between 8 a.m. and 5 p.m.
• On rare occasions, overnight work will be carried out while the métro is closed. Residents should not be affected by this work, as it will be done inside the tunnel.

To limit the impact on the neighbourhood, the following mitigation measures will be in place to reduce worksite noise:

• Temporary noise barriers at least 3 metres high will be installed all around the worksite.
• We will develop and implement a noise management program so that all worksite activities are within authorized noise limits.
• Electrical equipment will be used where available to reduce noise at the source.
• Crews will use vehicles and machinery with variable-volume backup alarms.
• Noise levels will be monitored at the site.

• The noise barriers installed around the worksite perimeter will keep dust inside the work area.
• Worksite fencing with anti-dust sheets will be installed at the entrance.
• The site will be hosed down during the demolition work to keep dust on the ground.
• Site access roadways will be cleaned during the work.

From start to finish:

• Gordon Street will stay open to traffic, but some parking spaces will be blocked.
• Flaggers will be present during more critical operations and for a few days of work in public areas.
• The De la Cours alleyway will remain accessible at all times.

• Two trees were removed from the site and replanted elsewhere in the neighbourhood.
• Some six trees had to be felled.
• Others were only trimmed to avoid damage during the work.

We are committed to limiting the environmental impact of our work. Each tree was analyzed to find solutions other than felling. We always try to transplant existing trees if they have good chances of survival.

New trees, shrubs and greenery will be planted after the work to enhance the space and leave it in good condition, as per borough requirements.
