Site work for a bridge / tunnel in Toronto, Ontario. Completed plans call for site work for a bridge / tunnel.
The Province of Ontario's New Subway Transit Plan for the Greater Toronto and Hamilton Area contemplates $CAD 28.5B in new subway construction in the Toronto area along four priority subway projects (collectively, the Subway Program). The Subway Program includes: - The Ontario Line, a new -15.5-kilometer rapid transit line running between the Ontario Science Centre and Exhibition/Ontario Place; - A three-stop Scarborough Subway Extension, a 7.8-kilometer extension of Line 2 from Kennedy Station; - The Yonge North Subway Extension, extending Line 1 from Finch Station to Richmond Hill Centre; and - The Eglinton Crosstown West Extension, a 9.2-kilometer extension of the under-construction Eglinton Crosstown LRT Line from Mount Dennis to Renforth Drive, with a possible connection to Toronto Pearson International Airport Advance Tunnel Contract - Description: The Advance Tunnel Contract package includes all tunnelling and related activities necessary to build the tunnel along the prescribed alignment, including the delivery of twin tunnels (metro size 5.6 m internal diameter), with launch and extraction shafts, utility relocations, headwalls for stations and emergency exit buildings (EEBs) and temporary support of excavation for EEB's, as required. The YNSE reference alignment requires that two Tunnel Boring Machines (TBMs) be launched from a temporary launch shaft located south of Langstaff Road East and adjacent to the CN rail tracks. The shaft will be located immediately west of the CN rail tracks and north of a location where the TBM tunnels run at shallow depth below the CN tracks for a distance of approximately 430 m. Given the TBM tunnels are located below the CN tracks, as part of the Advance Tunnel (AT) contract, a design solution has been developed whereby the CN tracks would be temporarily diverted to the east, thereafter the Advance Tunnel contractor will be required to undertake ground improvement / replacement works so that the TBM tunnelling can be undertaken without risk of major settlement or disturbance below or adjacent to the CN tracks. The Advance Tunnel (AT) Package includes, but is not limited to: - All tunnelling activities necessary to build the bored tunnel along the prescribed alignment through a minimum of 300m radius curves - Design and procurement of TBMs - Design, manufacturing, and installation of precast concrete tunnel liners (PCTLs) - Design and construction of launch and extraction shafts - Design and construction of prescribed headwalls for Emergency Exit Buildings (EEBs) and stations, as required - Design and construction of support of excavation (SOE) for Emergency Exit Buildings (EEBs), as required - Utility work including relocation and support in place of existing utilities - Protection of existing utilities and structures where needed - Clearing and grubbing (removal of debris/obstructions) at location of Tunnel launch shaft - Provisioning of access roads for construction laydown areas and work areas - Construction of CN Right-of-Way separation barriers to expedite safe corridor access and construction - Ground improvement / replacement under and adjacent to CN tracks and York Durham Sewage System. - Prescribed treatments for noise and vibration mitigation during construction of the tunnel, in the construction zone of influence Official bid documents must be obtained from www.merx.com and bid submissions must be done through the Merx platform. TIMELINE: RFQ D/B has closed. Three teams were shortlisted through a Request for Qualification (RFQ) process conducted earlier this year and are now invited to respond to the RFP. Selection is ongoing; IO and Metrolinx expect to award this tunnelling contract in late 2024.
