The Early Works portion of the GO Expansion project is one of three blocks of works to be done to accommodate two-way, all-day transit throughout the GTHA corridot. According to the Fall 2018 business case, this work represents: “including both on-corridor and off-corridor civil works such as new track, station improvements, grade separations and utility relocations, that are either enabling infrastructure for future service increases, needed state of good repair improvements or components that can be delivered early, to reduce schedule risk for the program.”
There are over 50 individual projects included in the early works program, including 40 smaller projects delivered as Design-Build or Design-Bid-Build, along with 12 larger projects delivered as Build-Finance and Design-Build-Finance. The latter includes the Davenport Diamond Rail Grade Separation Project, for which the winning bidder was selected in July 2019, and the Highway 401 Rail Tunnel, which began construction in March 2019, and the Stouffville Corridor Stations Improvement project.
