Ontario Construction News staff writer

Trillium Guideway Partners (TGP) has been selected to deliver the Ontario Line elevated guideway and stations contract. The team has signed a development and master construction agreement (DMCA) with Metrolinx, under a progressive design-build contract.

The Trillium Guideway Partners team includes:

  • Applicant Leads: Acciona Infrastructure Canada Inc. and Amico Major Projects Inc.
  • Design Team: WSP Canada Inc.
  • Construction Team: Acciona Infrastructure Canada Inc. and Amico Major Projects Inc.

“Participation in projects such as this that have a positive impact on decarbonization is an Amico goal. (We have) a strong partnership record with Acciona on Infrastructure Ontario projects and look forward to continuing that partnership,” Amico president Dominic Amicone said in a statement.

The DMCA incorporates a multi-stage design process called a development phase, according to the progressive design-build model. This phase allows for a collaborative approach between Metrolinx as the project owner and TGP as the contracting partner, who work together to finalize the scope, risk allocation and pricing of various elements of this contract.

Once the development phase has concluded, Metrolinx will have the option to sign a final target-price agreement with TGP, which would include final agreements on detailed designs and a negotiated price.

The scope of work includes three kilometres of an elevated guideway (bridge structures); five elevated stations (Riverside-Leslieville, Gerrard, Thorncliffe Park, Flemingdon Park, Science Centre), one emergency exit building, interface with the operations and maintenance storage facility as well as with the Eglinton Crosstown LRT Line 5 and sections of existing Metrolinx-owned rail corridor where Ontario Line trains will operate.
