Six teams have been shortlisted by Infrastructure Ontario (IO) and Metrolinx to perform a combined 13.8 kilometers (8.6 miles) of tunneling work for two of the province’s priority transit projects.
A Request for Qualifications (RFQ) was issued in March for the tunnel work on the Scarborough Subway Extension, which includes 7.8 kilometers (4.84 miles) of tunnels and the Eglinton Crosstown West Extension, which includes six kilometers (3.7 miles) of tunnels. Tunnels on both projects will be drilled using tunnel boring machines (TBMs).

"When our government was elected, we immediately reached out to listen to the market to ensure there was capacity and competition to bid on priority projects," said Ontario Minister of Transportation Caroline Mulroney. "The market has responded in an overwhelmingly positive manner and this shortlist is made up of a strong mix of Canadian and international bidders."
IO and Metrolinx say the teams were shortlisted based on criteria identified in the RFQ process, which included design and construction experience and the financial capacity to deliver a project of this size and complexity. Teams with the top three scores were then shortlisted for each project.
These shortlisted teams will be invited to respond to a Request for Proposals (RFP) to begin preparing their submissions that detail how the projects will be delivered with tunneling contracts expected to be awarded for the projects in mid-2021.
In a recent Metrolinx blog post, which detailed different methods of digging a subway tunnel, Metrolinx explains TBMs are custom built for each job, but the advantage of using TBMs is the speed with which they work once in the ground. TBMs can dig 10-15 meters (10.9-16.4 yards) per day.
“It takes you about a year to get one, but once it’s started and it’s going, it tends to be an efficient and safe method of work,” said Richard Tucker, a project director for the Ontario Line and Scarborough Subway Extension at Metrolinx.
The Scarborough Subway Extension is an 8-km (approximately 5-mile) extension of the Toronto Transit Commission’s (TTC) Bloor-Danforth Line 2. The Eglinton Crosstown West add 9.2 km (5.7 miles) to TTC’s future Line 5 and connect Mount Dennis Station to Renforth Drive.
The projects, along with the Ontario Line and the Yonge North Subway Extension, have been designated by the government of Ontario as priority transit projects and represent the largest transit expansion in the history of the province.
