TORONTO – Metrolinx and Infrastructure Ontario (IO) have selected Scarborough Transit Connect as the development partner ((known as the “Dev Co”) 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.
Scarborough Transit Connect is comprised of leading companies with the expertise to deliver a subway project:
- Applicant Leads: Aecon Infrastructure Management Inc., FCC Canada Ltd.
- Design Prime Team Member: Mott MacDonald Canada Limited
- Construction Prime Team Members: Aecon Infrastructure Management Inc., FCC Canada Ltd.
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.
Scarborough Transit Connect was evaluated and selected based on criteria identified in the Request for Proposals process that began in February 2022. Criteria included design and construction methodology, approach to managing the project, and corporate overhead and profit fees for the project. The open, fair and competitive procurement process was overseen by a third-party fairness monitor.
Metrolinx will deliver the 7.8-kilometre Scarborough Subway Extension in two large contracts: the SRS contract and the Advance Tunnel contract, which is currently under construction. The subway will remain publicly owned by the Province of Ontario and will be operated by the TTC as part of Line 2.
The Scarborough Subway Extension is one of the five priority transit projects in the Greater Toronto and Hamilton Area. The other projects include the Yonge North Subway Extension, the Eglinton Crosstown West Extension, the Ontario Line and the Hamilton LRT.
