Metrolinx and Infrastructure Ontario (IO) announced that Scarborough Transit Connect has been selected as the development partner to enter the development phase of the Stations, Rail and Systems (SRS) contract for the Scarborough Subway Extension project.

The SRS package for the Scarborough Subway Extension is being delivered using a Progressive Design-Build (PDB) model.

The Scarborough Subway Extenstion will extend the TTC’s Line 2 subway service nearly eight kilometres farther from the existing Kennedy Station northeast to McCowan Road and Sheppard Avenue, including three new stations with connections to Line 5 (the Eglinton Crosstown LRT), GO train and bus services, TTC bus service and Durham Region Transit.

Scarborough Transit Connect is comprised of leading companies with the expertise to deliver a subway project:

  • Applicant Leads: Aecon Infrastructure Management Inc., FCC Construccion S.A.
  • Design Prime Team Member: Mott MacDonald Canada Limited
  • Construction Prime Team Members: Aecon Infrastructure Management Inc., FCC Construccion S.A.

The scope of work 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 the Advance Tunnel contractor on remaining work.

The Progressive Design-Build model incorporates a multi-stage design process called a development phase. 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. Currently, 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.

STC has executed a development phase agreement with IO and Metrolinx to collaboratively finalize the scope, cost and schedule of various elements of the project over an 18-month period, with certain early works activities commencing during this phase. Upon successful completion of the development phase, an implementation phase will commence under a target price contract.
