Place-Saint-Henri

Ongoing work at Place-Saint-Henri station

 

Project summary

We are currently working on installing elevators at Place-Saint-Henri station, building two new entrance buildings to replace the two secondary station entrances and refurbishing Place Saint-Henri. Once the work is completed, access to the station by elevators will be via the entrance located on place Saint-Henri.


Duration of the work: November 2020 to fall 2023

Description of the work: Elevator installation, construction of two entrance buildings and refurbishment of Place Saint-Henri

Métro impacts: the two entrances located on the north and south sides of Saint-Jacques Street are closed for the entire duration of the work.The main entrance, located on Saint-Ferdinand Street, will remain open.

Bus impacts: No

Impact on customer trips

The main entrance, located on Saint-Ferdinand Street, remains opened. However, the two other entrances, located on the north and south sides of Saint-Jacques Street, are closed for the entire duration of the work. This closure is necessary for the construction of two new entrance buildings.

During the work, no bus stops are relocated, and the bus loop next to the main entrance will remain accessible.

Partitions will be installed on the platforms and in some areas inside the station, but they will not affect customer trips.

Impact on local residents

Texte important
  • All businesses near the worksite will remain open. Safe access will be provided.
  • The École Saint-Henri and public pool will remain accessible at all times.
 

Phase 2: January 2021 until end of work

  • One lane on Saint-Jacques will be closed to traffic near the north entrance.
  • Place-Saint-Henri will become one-way going south between Saint-Jacques and Notre-Dame.
  • A large portion of the public parking area south of the worksite will reopen in June. And during the month of July 2021, it will be entirely accessible.

Any construction work likely to generate noise will generally be scheduled between 7 a.m. and 7 p.m. In accordance with municipal by-laws, some work may continue over weekends to keep the construction on schedule. Also, some work absolutely must be done outside of métro service hours and may be carried out at night

Start of bedrock excavation work

In early June 2021, we will start excavating the bedrock. This work will serve to dig two vertical elevator shafts, each 15 metres deep. Based on the current schedule, the work will continue until early 2022.

The work will begin at the site south of Saint-Jacques Street. Then, once the retaining walls are installed and ground excavation is completed at the north site, we will continue excavation at both sites simultaneously.

Using a drilling rig, we will make holes in the bedrock, which will then be fractured using a hydraulic drill. This step will cause noise, but it will be dampened by the fact that we will be working five metres underground instead of at street level. Vibrations may also be felt near the worksite.

Could buildings near the worksite be damaged during the excavation work?

The required excavation work will generate vibrations that may be felt by residents near the worksite. An independent consulting firmwas hired  to survey (mainly photograph) all buildings around the worksite. These inspections will document the condition of the buildings before and after construction. In the unlikely event that any damage is reported, an expert opinion could help to determine whether the damage is the result of the vibrations produced by the work site. Property owners affected by this measure will be notified accordingly.

Anti-dust sheets will be installed on all the worksite partitions to limit dust dispersal.

Texte important

We care about the quality of life of residents living close to our facilities. Rest assured that we will take all measures necessary to keep the impact on residents, businesses and customers to a minimum.

Learn more about the project

This kind of major construction must be done in several steps.

South side

We have finished installing the retaining walls and have nearly completed the soil excavation in this area. We will soon start digging the elevator shaft for the new entrance building. Over the next few weeks, we will also finish relocating the aqueduct and sewer conduits west of the site.

North side

Preparatory work is progressing quickly on the north side. Our various external partners have relocated the underground telecommunications cables, but there is still some work to be done, including the relocation of a sewer conduit. Once this step is complete, we will begin excavation and then install the retaining walls.

Relocation of underground infrastructure

As soon as we break ground, the first step is to relocate various underground infrastructure, such as conduits for power, natural gas, telecommunications and electrical cables, to a safe area.

Retaining walls, excavation and concrete work

Next, temporary walls must be installed to support the ground as we dig deeper and deeper into the excavation zone. After, we can begin excavating and breaking up the rock bed using a method to be decided later (either micro-blasting or mechanical equipment). We will then demolish the existing station entrances as they will be replaced by new above-ground entrance buildings. Finally, we will perform concrete work to construct the new entrance building foundations, corridors leading to the elevators, elevator mechanical rooms and elevator shafts.

Construction

Once the concrete work is finished, we will build the new entrance buildings, install the elevators in the shafts and set up all their electrical equipment in the mechanical rooms.

Exterior work

Refurbishment of Place-Saint-Henri will begin next, including earthmoving and urban furniture installation.

Electrical equipment testing

Finally, we will conduct various tests to ensure that the elevators are working properly.

  • Place-Saint-Henri station was designed by architect Jean-Louis Lalonde and designer Julien Hébert, who is better known for creating the world-renowned logo of the 1967 Universal Exposition.
  • The station was originally going to be called Les Tanneries, after the name given to the neighbourhood in the 18th century due to its large number of leather tanneries.
  • The station’s name instead pays homage to Place Saint-Henri, more of a small street than a real public square. The neighbourhood first became known as Saint-Henri in 1810, when a chapel of the same name was established there.

Improving this station’s accessibility is part of phase 1 of our Accessibility program, which aims to make 14 of our métro stations more accessible by 2025. For more information, visit this web page.

The Accessibility program is made possible thanks to the additional funding announced by the federal and provincial governments to speed up universal accessibility work and make the 41 métro stations accessible by 2025.
