Three bidders for Scarborough extension

Scarborough metro extension Metrolinx and Infrastructure Ontario (IO) have issued a Request for Proposals to three bidders for the stations, rail and systems (SRS) package for the Scarborough metro extension project in Toronto.

The three consortia are:

  • Dragados – comprising Dragados and Aecom Canada;
  • KSX Integrated Design-Builders – comprising Peter Kiewit Sons and Lavalin Constructors; and
  • Scarborough Transit Connect – comprising Aecon Infrastructure Management, FCC Construccion and Mott MacDonald.

The three consortia, selected following the RFQ process, will prepare their proposals and detail the way they will deliver the project until the summer when their plans must be submitted. This includes the design and construction of the stations and emergency exit buildings, tracklaying, traction power substations and modifications at Kennedy Station, the installation of the signalling system un the tunnel and the commissioning of the operational systems.

The Scarborough Subway extension is implemented into two large contracts covering the SRS package and the advance tunnel contract won by Strabag in March 2021 and in June the construction works have started.

The project covers the construction of a 7.8-km metro extension of TTC Bloor-Danforth Line 2 from the existing Kennedy Station northeast to McCowan Road/Sheppard Avenue. The line will include three new stations at Lawrence Avenue and McCowan Road, Scarborough Centre and a terminal station at McCowan Road and Sheppard Avenue. The extension will provide transit connections to Line 2, Line 5 – Eglinton Crosstown LRT, GO train service via Stouffville line and Durham Region Transit bus service.

The Scarborough metro extension is part of transit expansion strategy covering four transit lines in the Greater Toronto Area announced by the Province of Ontario in 2019. Last year, the Government of Canada announced funding for the four transit projects which includes Scarborough extension, Yonge North metro extension, Ontario Line and Eglinton Crosstown West Extension. All these projects are at planning phase and procurements for the metro programme are being staged to ensure each project is delivered successfully.
