Scarborough Subway Extension Advance Tunnel Phase in Toronto

project awarded

This project includes the development of the Scarborough subway extension in Greater Toronto. The Scarborough Subway Extension (SSE) is a fully underground extension of Toronto’s ‘Bloor-Danforth’ subway Line 2. The works involve a 7.8-kilometer extension of Line 2 from Kennedy Station to McCowan Road/Sheppard Avenue.The Extension will reduce travel times and improve access to jobs, schools and other destinations. The three-stop extension will provide seamless travel for Scarborough residents heading into and out of the city with new stops at Lawrence East, Scarborough Town Centre, and McCowan Road/Sheppard Avenue.The SSE will be delivered by way of an advance tunnel contract (the “Advance Tunnel Contract”), followed by a subsequent contract to construct the stations and other facilities, fit-out the tunnel, and install and commission the systems (referred to as the “Stations, Rail and Systems”). The Advance Tunnel Contract and the SRS Contract will both be delivered as P3 projects.  Specifically, the delivery model for the Advance Tunnel Contract will be design-build-finance and the delivery model for the SRS Contract will be design-build-finance-maintain (with maintenance for only a portion of the scope).
