Réseau express métropolitain (REM), Canada, Engineering, Procurement & Construction

The Réseau express métropolitain (REM) is an electric and fully-automated, light-rail transit network designed to facilitate mobility across the Greater Montreal Region. It is the largest public transit project undertaken in Québec in the last 50 years. Spanning 67 kilometres of double track and boasting 26 stations, it will connect with existing bus networks, commuter trains and three lines of the Montréal metro. The stations will be accessible by foot, bike, cars and taxi. They will also integrate universal mobility options, connect to bus stations and park & ride lots, and offer passengers a variety of travel options between home and the station. 

Solutions

A unique approach

We took a one-team approach on tendering, with seven companies working together as one integrated unit. Designers, construction managers, planners and estimators all worked together for 20 months to get the most cost-effective bid for the client. 

We also provided an integrated schedule at tender whereby design, procurement and construction were all integrated with their approach on the schedule’s output.  

Embracing advanced technologies

We are using advanced digital solutions to strengthen our capabilities on the project. The collaborative approach of Building Information Modelling (BIM) means we can carry out and visualize the design and construction on one integrated platform. The digital mock-up and corresponding data provided from this approach allow us to prevent challenges including delays.

Overcoming labour shortages

Due to labour shortages in Montreal, we chose offsite manufacturing instead of onsite construction for some key elements. The project is designed accordingly to use pre-cast instead of in situ concrete, including for structures and more specifically all elevated guideway.

Saving time and money on stations

The project will have more than 26 stations. Another cost and time-saving decision was to modularize station design instead of developing a unique design for each station. This allows us to make them more quickly and economically at every stage, from procurement to construction to maintenance. 

Results

The Réseau express métropolitain is the newest in a long series of signature LRT infrastructure projects in which we’ve been involved in Canada. It’s also the most exciting new phase of light-rail transit since the creation of Montreal’s metro 50 years ago. The new network will greatly increase the ability of residents to get around their city and make new connections. The route will also take commuters over the New Champlain Bridge Corridor Project, another significant project that SNC-Lavalin is proud to take part of.
