RFQ issued for stations, rail and systems contract for the Yonge North Subway

Infrastructure Ontario and Metrolinx have released a Request for Qualifications (RFQ) or the stations, rail and systems package for the Yonge North Subway Extension.

The Yonge North Subway Extension will extend the TTC’s Line 1 subway service approximately eight kilometres from the existing terminus at Finch Station into the City of Richmond Hill.

The RFQ outlines the scope of work to include the design, construction, supply, integration, and commissioning of the following key elements:

• Five new subway stations, and associated bus facilities.
• Emergency exit buildings, traction power substations, and tunnel cross passages.
• All rail and signalling systems.
• A train storage facility to support Line 1 operations.
• Connections at Finch Station, including modifications to the existing tail track.
• Integration with existing TTC Line 1 infrastructure and work underway through the advance tunnelling contract work, and the Transit-Oriented Communities program.
• Provisions to enable the Transit-Oriented Communities work.

Three of the stations – Steeles, Clark, and Royal Orchard – will be built underground. Bridge and High Tech stations will be at surface level.

With a contract for tunnelling recently awarded, both major contracts required to deliver the Yonge North Subway Extension are now in motion. Work has already started to prepare for the excavation of the launch shaft, where the future tunnel boring machines will begin digging.
