Infrastructure Ontario and Metrolinx have issued a request for qualifications (RFQ) for interested parties to design, build and finance the Davenport Diamond Rail Grade Separation project, part of Metrolinx’s GO Regional Express Rail (RER) program.

The RFQ outlines the work required at the Davenport Diamond, located in Toronto along the Barrie Rail Corridor. The scope of work includes:

  • construction of a grade separation structure between the north/south GO Rail corridor and east/west CP Rail corridor
  • implementation of a pedestrian underpass to restore east/west connection at Paton Road
  • erection of retaining walls forming the approaches of the grade separation structure, topped with noise barrier walls and superimposed cladding to minimize impacts on the community
  • construction of a rail guideway offset within the corridor during construction to accommodate a temporary diversion track and a temporary rail diamond
  • modification of an existing at-grade road crossing at Wallace Avenue to become a road under rail grade separation
  • public realm enhancements, including artwork on the structure cladding and new pedestrian and cyclist routes
  • provisions for future electrification implemented within upgraded rail infrastructure to accommodate future electrified GO train service

“The Davenport Diamond Grade Separation is a significant infrastructure project that will reduce delays and improve service on the GO rail network. It will play a crucial role in supporting GO Regional Express Rail service and the electrification of GO service on the Barrie Corridor,” said Steven Del Duca, Minister of Transportation, in a release.

The RFQ is the first step in the procurement process to select a team to deliver the project.Infrastructure Ontario and Metrolinx will evaluate submissions to prequalify project teams with the relevant design and construction experience.

Teams that qualify will be invited to respond to a request for proposals early in 2018. Interested companies must register with www.merx.com to download the RFQ.

The project is being delivered using Infrastructure Ontario’s Alternative Financing and Procurement (AFP) model.
