Fullum mechanical ventilation station

Construction of the Fullum mechanical ventilation station

Project summary

As part of our program to refurbish métro infrastructure, we are building the Fullum mechanical ventilation station in Olivier-Robert Park.

There is already a station on that part of the Green line, but it was built during the second half of the 1960s. It has now reached the end of its service life and must be replaced. Our project involves building a new, quieter and more efficient ventilation station that meets the new safety standards and complies with City of Montréal noise bylaws. 

Duration of the work: September 28, 2018, to summer 2021

Description of the work: Construction of a new mechanical ventilation station

Métro impacts: No

Bus impacts: No

Impact on customer trips

The project has no impact on customer trips.

Impact on local residents

In compliance with the new municipal by-law in the Ville-Marie borough, a pedestrian walkway has been installed on Fullum Street, beside the park, for May 2020. The walkway has taken the place of the bike path, which has been relocated to the west. This required the removal of some parking spaces on the west side of Fullum Street, between De Maisonneuve Boulevard and Oliver-Robert Street.

  • Flag persons are present when trucks enter or exit the worksite on both De Maisonneuve and Fullum.
  • The 34 Sainte-Catherine bus stop was removed. The closest bus stop is at the corner of Dufresne.
  • The bicycle path on Fullum remains open.
  • Any construction work likely to generate noise will be scheduled between 7 a.m. and 7 p.m. on weekdays. In accordance with municipal regulations, some work may at times have to continue over the weekend to keep the project on schedule .
  • Excavation work will produce vibrations that may be felt by residents living next to the worksite. We have hired an independent consulting firm to survey all buildings (photographs) around the worksite. The inspections will serve to document the condition of buildings before and after construction. In the unlikely event that any damage is reported, an expert opinion could help determine whether the damage is the result of the vibrations produced by the project. Property owners concerned by the inspections will be notified accordingly .
  • A traffic and signage plan was prepared by a specialized firm and coordinated with the Ville-Marie borough and the City of Montréal. The plan will minimize the impact of the project on vehicle, cyclist, pedestrian and emergency services movements.

Learn more about the project

A mechanical ventilation station is a large infrastructure located between two métro stations that is equipped with two powerful fans designed to extract hot air from the métro system through inlets fitted with air vents. Ventilation stations built for the original métro system extract around 60,000 cubic feet of air per minute, while the new ventilation systems extract around 240,000 cubic feet per minute. Huge noise suppressors mitigate the noise from these fans to ensure quiet for residents living close to a ventilation station.

  1. Preparation of worksite
    Fencing off the worksite
    Setting up the worksite and installing equipment
  2. Excavation at ground level
  3. Excavation in the rock bed
    Micro-blasting will be required to break into the rock bed. In this case, it is the fastest, most efficient way to proceed. Another option would have been jackhammering. However, given the volume of rock to be excavated, jackhammering would be less efficient, would take significantly more time, and be much more disruptive as the noise is constant.
  4. Installation of a membrane to ensure water-tightness of all infrastructures
  5. Concrete work for ventilation station
    Concrete work for all infrastructures
  6. Installation of mechanical and electrical equipment, as well as architectural finishes and exterior design
    Delivery of equipment to work site
    Installation of equipment
    Performance testing on mechanical equipment
    Construction of ventilation station’s external structure
