The Toronto Transit Commission (TTC) awarded us the contract to build Leslie Barns, a 27,000 m2 streetcar maintenance and storage facility located on the southeast corner of Lakeshore Boulevard East and Leslie Street in Toronto.
The purpose of the facility is to service, repair, inspect and store 130 new electrically powered light rail vehicles that will replace the existing fleet of streetcars in Toronto.
For this mandate, we built and installed the following:
New storm sewer segments (which included decommissioning the outgoing main storm sewer and performing other specialized work)
A fibreglass-reinforced plastic (GRP) lining system
A new sanitary sewer segment (including the connection in the work area to accommodate the proposed light rail)
A maintenance building that can accommodate up to 20 vehicles at a time (including mechanical and control rooms, an electrical substation, offices and areas for specialized maintenance and repair equipment)
Approximately 8 km of siding for up to 100 light rail vehicles
A parking lot
Managing complex systems
We skillfully coordinated the layout, elevation and physical installation of many complex underground systems.
Construction site on a former dump
We installed a methane capture system to treat the gas fumes that dissipated through the stacks when concentrations exceeded certain levels.
We coordinated a multitude of tasks on a huge site and managed the delivery of specialized equipment from abroad.
A very busy site
We successfully completed the project despite its location—at one of Toronto’s busiest intersections (Leslie Street, Queen Street and Lakeshore Boulevard).
