Place-Saint-Henri

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

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 were notified accordingly.

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

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.
