Scarborough Subway Extension stations, rail and systems contract awarded to Scarborough Transit Connect

Scarborough Transit Connect (Dev Co) has been selected by Metrolinx and Infrastructure Ontario to be the development partners for the Scarborough Subway Extension’s Stations, Rail and Systems (SRS) package – the second of two contracts being used to deliver the 7.8-kilometer (4.85-mile) extension of Toronto Transit Commission’s (TTC) Line 2. The government of Ontario has included the Scarborough Subway Extension as one of five transit priority projects aimed at improving regional mobility.

Dev Co will enter the development phase of the SRS contract, with a scope of work that includes:

• Design and construction of three new underground stations and bus terminals at each station.
• Design and construction of emergency exit buildings and service buildings and traction power substations.
• Installation, testing and commissioning of all systems equipment and interconnection with existing TTC systems.
• Design, supply, installation, testing and commissioning of all rail and track components and a pocket track east of Kennedy Station.
• Coordination with Strabag Inc. team, the Advance Tunnel contractor, on remaining work

The project is being delivered using a Progressive Design-Build model that incorporates a multi-stage design process called a development phase. Infrastructure Ontario and Metrolinx says this phase allows for a collaborative approach between the project owner, the contracting partner and other stakeholders who work closely together to finalize the scope, risk allocation and pricing of various elements of the project.

The development phase for SRS is anticipated to be completed in approximately 18 to 24 months. Once the development phase has concluded, Metrolinx and the Scarborough Transit Connect team will then have the option to sign a final agreement to proceed to the construction phase, which would include agreements on detailed designs and a negotiated price.

The team making up the Scarborough Transit Connect entity includes:
