Structural Engineering Consultant to Pomerleau (General Contractor)
Situated on an 18 acre site, the Leslie Barns facility houses, services and maintains 100 of the Toronto Transit Commission’s new Flexity Low Floor Streetcars. Remediation costing approximately $90 million was conducted by the City of Toronto to remediate the soils at the site in order to make the development feasible. A preceding contract was separately tendered to install a series of Rammed Aggregate Piers (RAP) to improve the soil bearing capacity prior to construction of the Leslie Barns facility.
The facility includes four buildings – a 17,510 m2 Carhouse building for maintaining and servicing the streetcars, a 685 m2 Traction Power Substation, 16 m2 Yard Control Huts, and a 25 m2 Irrigation Hut. The site also includes a storage yard for 100 vehicles, an employee parking lot, a storm water management pond, and various landscaping elements for aesthetics and noise mitigation. The Carhouse has 30 service bays across 7 tracks, with pits, mezzanines, overhead cranes, and monorails for servicing the underside and upper portions of the vehicles. The Carhouse accommodation block contains a loading dock, material storage rooms, and various office-related space.
Challenge: Our client faced significant challenges in coordinating the building foundations with the pre-constructed RAP elements and the required underground services. We conducted a review of the drawing information to determine if sufficient information was available to them in order to perform their work.
Solution: We conducted a comprehensive drawing review to determine if sufficient information was available for our client to perform their work. A report summarizing our findings and a series of meetings were held to review the results of our assessment.
