Bellechasse bus garage

New bus garage in 2022

The Bellechasse bus garage will be built on the block formed by De Gaspé Avenue and Bellechasse, Marmier and Saint-Dominique streets in Rosemont–La Petite-Patrie. Located in the heart of the city, close to many transportation corridors, it is part of our strategy for accommodating 300 new buses. The bus centre will also be equipped with the facilities needed to house a fleet of fully electric buses.

Cutting-edge technology

The Bellechasse bus garage will be innovative, functional and unique. Once complete, it will be the first bus garage in North America to be fully underground and equipped with the facilities to operate an entire fleet of electric buses.

The centre will have two connecting structures: an underground three-level garage where the buses will be parked and maintained and a one-storey ring-shaped building with lots of windows where administrative offices and employee facilities will be located. The ring-shaped building will also have a fire prevention station and a passenger revenue operational management workshop.

The centre’s operations (bus traffic, maintenance and parking, and employee parking) will be located inside the building to reduce the impact on the neighbourhood.

Finally, there will be a large green space accessible to the public.

Once construction is complete, there will be underground parking spaces reserved for the employees on duty.

  • Buses will be put on the road to provide customers with daily transit service
  • Preventive maintenance and mechanical repairs on buses will be performed
  • Electric buses will be charged
  • There will be administrative offices and areas for maintenance employees and drivers
  • There will be an STM fire prevention station
  • There will be a passenger revenue operational management workshop

The building will have a high-quality environmental design. We aim to obtain LEED v4 Gold certification. The complex will incorporate:

  • Natural light
  • Universal access
  • A building envelope with superior energy efficiency
  • An energy efficient mechanical and heat recovery system
  • Water catchment and recycling
  • Recovery of construction materials, when possible

Safety around the worksite during blasting

Blasting work at the site of the future Bellechasse bus garage starts today and will continue until March 2020.

During a blast, pedestrian, cyclist and vehicle traffic will be stopped around the site for only a few minutes. This is a totally normal procedure that ensures the safety of people moving around the worksite. Once the blast is over, traffic will be allowed to resume.

Bike path and traffic on Bellechasse Street
Traffic will be stopped in the bike path and the road for approximately five minutes between 4 p.m. and 7 p.m. from Monday to Thursday, and between 11 a.m. and 1 p.m. on Friday. This schedule will be in effect as of today until March 2020.

Dog park access
The dog park will not be accessible for approximately 30 minutes between 4 p.m. and 7 p.m. from Monday to Thursday, and between 11 a.m. and 1 p.m. on Friday. This schedule will be in effect as of today until March 2020.

How will people be warned?
A few minutes before a blast, our general contractor’s employees will go to pre-determined locations and will act as signal persons. For your safety, we ask that you follow their instructions.

Also, signs blocking off the sidewalks and bike path will be installed just before the blast. Please follow the signs.

Why can’t blasting take place at the same time every day?
We understand that it would be easier if blasting happened at the same time every day. However, there are many factors involved in blasting, such as site preparation and equipment installation. This is why we have reserved periods of two to three hours for this work.

In preparation for the construction of the future Bellechasse bus garage, we will carry out blasting operations to excavate rock and move the project forward. Blasting should start on June 20, 2019. This work will last until March 2020.

What measures will be implemented to ensure safety around the worksite?

  • The construction site has already been fenced off, and blasting will be done within its perimeter.
  • Blasting mats will be installed over the rock to contain rock fragments.
  • Safety instructions will be posted around the site.
  • No explosives are stored on site.
  • A professional firm specialized in monitoring vibrations has been mandated to ensure compliance with the standards established by the City of Montréal and the STM.
  • During a blast, pedestrian and cyclist traffic will be interrupted for a few minutes around the site.
  • Installation of Carbon monoxide detectors : Gestion Monox Inc. has been mandated to install carbon monoxide detectors in buildings within 100 metres of the site. If your property is located in the targeted area, Gestion Monox Inc. will get in touch with you. For more information about Gesiton Monox Inc.

What is the usual procedure for warning nearby residents that a blast is imminent?

  1. 12 whistle or siren sounds
  2. 30-second wait
  3. Blast
  4. One long whistle or siren sound
  5. End of blasting

Schedule
In general, we plan on performing about one blast per work day. The schedule, however, may vary depending on the progress of the work

Will residents feel vibrations and hear noise?
Close to the worksite, residents may feel vibrations or hear noise when the blast goes off, which is totally normal.

Why are we using blasting for excavation?
The hardness and nature of the rock determines whether blasting is needed or not. When the rock is really hard, compact and large in size, it is very difficult to break it up using a method other than blasting. Given its efficiency, this method will reduce the duration of the work. 

The work will take place from spring 2019 to spring 2022. It will be carried out in two phases. The first phase will last from spring 2019 to spring 2020, and will involve preparatory work including building demolition, removal of materials and waste, soil decontamination and excavation of the rock bed.

The second phase will last from spring 2020 to spring 2022, and will involve construction of the new bus garage.

During Phase 1, the work will generally take place Monday to Friday from 7 a.m. to 7 p.m., the hours set by the Borough.

  • Casgrain Avenue is permanently closed between Bellechasse and Marmier streets.
  • Access to the dog park is being maintained (entry located on Marmier Street at the intersection with De Gaspé Avenue).
  • We will give priority to trucks exiting and entering on Marmier Street in order to keep traffic on Bellechasse Street to an absolute minimum.
  • The bike path on Bellechasse Street remains in service. 

  • We have introduced a traffic maintenance plan, established by a specialized firm, for motorists, pedestrians and cyclists in the area.
  • An inspector will be on the work site to ensure compliance with regulations on noise levels and work hours.
  • Water spraying will be carried out during demolition and excavation to reduce dust.

During construction, the contractor will be responsible for planning and managing parking for workers to keep their use of local residents’ parking spaces to a minimum.

The rock bed will be excavated by blasting. The hardness and nature of the rock determines whether micro-blasting is needed or not. When the rock is really hard, compact and large in size, it is very difficult to break it up using a method other than blasting. In addition, given the volume of rock to be excavated, jackhammering would be less efficient, take significantly more time, and be much more disruptive as the noise produced is constant.

We are aware of the inconveniences this work might cause. Our contractors will respect the prescribed hours. During the week, work and traffic movements must occur between 7 a.m. and 7 p.m.

The STM will also deploy an inspector on the worksite to ensure compliance with standards and implement mitigation measures to reduce nuisances (noise, dust). The contractor must introduce a traffic maintenance plan, wich will be approved by the borough, to reduce impacts in the area.

The demolition work is now fully complete. We have started excavating the ground, which will take until the end of June. In compliance with municipal by-laws, the work will take place between 7 a.m. and 7 p.m.We have to excavate the equivalent of five floors.

As all of the excavated ground must be removed from the site, there will be more trucks than usual during this phase. The trucks will leave the site via the exits on Marmier and Bellechasse streets. Flaggers will be present at all times during truck movements to ensure user safety.  Please use caution around the site and follow safety instructions and signs.

 

Have you noticed that fences have gone up around the worksite? We are preparing the ground to start excavation work on the future Bellechasse bus garage. Over the next few weeks, truck traffic will increase in the area. Please use caution around the site and follow safety instructions and signs.

 

June 2019:

  • The borough council of the Borough of Rosemont–La Petite-Patrie to confirm the PPCMOI
  • Holding of a public consultation by the Borough of Rosemont–La Petite-Patrie

This work is made possible by funding provided by the Ministère des Transports du Québec and Infrastructure Canada.

We are aware of the inconveniences this work might cause. Rest assured that we will take all measures necessary to keep impacts on your activities to a minimum.
