Shoring Contractor:
Soletanche Bachy Canada

Services Provided

InGeo Design was engaged to provide excavation shoring design and monitoring services for the West Portal of the Eglinton Crosstown Light Rail Transit (LRT) project, Toronto’s 19-kilometre transit corridor that connects the city from east to west. The West Portal serves as a critical transition zone where the LRT moves from a tunneled underground alignment to above ground service.

Working alongside Soletanche Bachy Canada as the shoring contractor, InGeo was responsible for delivering excavation support within a tight urban corridor.

Key Challenges

  • Ensuring design takes into account seamless transition between other activities on site and other phases
  • Meeting fast-paced construction timelines with minimal disruption

InGeo’s Role & Scope

  • Design of a soldier pile and lagging system with a single level of tiebacks
  • Detailed tieback stressing and on-site field reviews to validate design performance
  • Deployment of monitoring instrumentation to ensure excavation safety and accuracy:
    1. Inclinometer Monitoring
    2. Pile Target Monitoring using a total station

Through technical clarity, rapid turnaround, and deep infrastructure experience, InGeo Design played a key role in supporting the successful excavation of the West Portal.
