Infrastructure Ontario has announced that the Request for Proposals (RFP) stage has closed for the Davenport Diamond Rail Grade Separation project.

The project involves the upgrading of the Davenport Diamond, one of the last high-traffic rail crossings in Toronto. The development works include construction of a grade separation structure between the north/south GO Rail corridor and east/west CP Rail corridor to minimize delays to GO service, 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, and etc.

Following a fair, open and transparent Request for Qualifications (RFQ) process, three teams - Davenport Construction Partners, Graham Commuter Rail Solution and Steelhead - were shortlisted and invited to respond to a Request for Proposals in February 2018. All three teams have submitted proposals. 

Over the next few months, submissions will be evaluated and a successful proponent is expected to be announced in spring 2019.
