Government of Ontario issues RFQ for Yonge North Subway Extension tunnels project
The government of Ontario has issued a request for qualifications (RFQ) for expert teams interested in building the Yonge North Subway Extension tunnels.
The advanced tunnelling RFQ offers interested companies an opportunity to be included in the bidding process by asking them to present their qualifications and construction expertise.
The package of work includes designing the tunnels, supplying the tunnel boring machines and building the launch shaft and extraction shaft that will be used to lower the tunnel boring machines into the ground and bring them to the surface again. The RFQ also includes design and construction of the walls that will support the underground stations and emergency exit buildings and relocating existing utilities along the route.
The successful tunnelling team will dig out the tunnel for the subway extension that will bring Toronto Transit Commission Line 1 service to Vaughan, Markham and Richmond Hill.
Work has started at Finch Station on early upgrades to accommodate future subway service.
Metrolinx and Infrastructure Ontario will review the submissions made through the advance tunneling RFQ and will create a shortlist of qualified teams that will be invited to bid on the tunnelling contract through a request for proposals.
