CANADA: Infrastructure Ontario and Toronto area transport agency Metrolinx have appointed the Scarborough Transit Connect consortium as Stations, Rail & Systems development partner for the Scarborough Subway Extension project.

Scarborough Transit Connect comprises applicant leads Aecon Infrastructure Management and FCC Canada, design prime team member Mott MacDonald Canada and construction prime team members Aecon Infrastructure Management and FCC Canada.

The 7·8 km metro extension from Kennedy to Lawrence, Scarborough Centre and Sheppard will be operated as part of Toronto Transit Commission’s Bloor-Danforth Line and is intended to replace the Scarborough Rapid Transit light metro line opened in 1985. SSE is being developed through two major contracts, with civils work already underway under the Advance Tunnel construction contract.

The Stations, Rail & Systems contract includes design and construction of the three underground stations, associated bus facilities, emergency exit buildings, service buildings and traction power substations. It also includes installation, testing and commissioning of track and railway systems and integration with existing TTC systems.

A progressive design-build model is being used, with an initial 18 to 24 month development phase, during which there will be a collaborative approach between the project owner, development partner and other stakeholders to finalise scope, risk allocation and pricing.

Metrolinx and Scarborough Transit Connect will then have the option to proceed to the construction phase, with agreements on detailed designs and a negotiated price.
