Strabag wins Eglinton Crosstown West Extension – Advance Tunnel 2 contract

The contract includes a 500m tunnel from east of Jane Street to Mount Dennis Station.

WSP Canada and Dr G Sauer & Partners Corp will provide the design expertise.

The Eglinton Crosstown West Extension Advance Tunnel 2 project is being delivered through IO’s public-private partnership (P3) model, which transfers appropriate risks associated with design, construction and financing of the project to the private sector.

Enabling works for the project are under way and major construction is expected to begin later this year.

The Eglinton Crosstown West Extension Advance Tunnel Contract 2 scope of work includes:

• Design and supply of mining and tunnelling equipment
• Detailed design and construction of the launch and extraction shafts and tunnel portal east of Jane Street
• Detailed design and construction of the tunnel between the portal and Mount Dennis Station using the sequential excavation method
• Modifications at Mount Dennis Station to accommodate extended Eglinton Crosstown LRT service; and
• Utility work and road modifications along Eglinton Avenue West to accommodate construction activities.

West End Connectors, a consortium of Aecon, Dragados and Ghella, was awarded the Advance Tunnel contract in 2021 and launched the two TBMs – Rexy and Renny – in 2022.

The extension is one of Ontario’s four priority subway projects for the Greater Toronto Area. Ontario is investing C$70.5bn (US$51.6bn) over the next decade on the largest subway expansion in Canadian history, which includes the Eglinton Crosstown West Extension, the Ontario Line, the Scarborough Subway Extension, and the Yonge North Subway Extension.
