Cross-section of a Tunnel Boring MachineTunnel Boring Machine

The construction of new tunnels under Eglinton Avenue is done by tunnel boring machines or TBMs. Each TBM moves forward by pushing off against concrete segments. The operator advances the machine as soil is removed from the TBM face through a conveyor system. The launch pit remains active for removal of muck/spoils.

Launch of the Tunnel Boring Machine

The Eglinton Crosstown tunnel will consist of side-by-side or twin tunnels. Each tunnel will be 6.75 metres internal diameter. Initially, one machine will begin excavation; the other will follow on a parallel course soon after.

Launch Shaft Operations

To keep the tunnel safe for the crew a ventilation system pumps fresh air into the tunnel and exhaust air is moved out of the tunnel. Cranes remain in position during the mining operation; muck will be hauled out and new concrete tunnel segments will be delivered.

Tunnelling Begins

Tunnel boring machines will work beneath Eglinton Avenue, allowing business activities and traffic to continue. A single TBM will tunnel 75 metres per week, and each machine is capable of moving 500 cubic metres of earth per day. The machines are made in Toronto by Caterpillar Tunneling Canada Corporation, formerly LOVAT, a world leader in tunnel boring machine manufacturing.

Alternative Financing and Procurement (AFP)

The public-private partnership model has been underway in Canada for 20 years and has been used in 165 projects, including the Canada Line rapid transit project (Vancouver), Autoroute 25 in Montreal and the Trans-Canada highway in Atlantic Canada. In Ontario, AFP has been used for the Pan AM games athletes’ village, Ottawa Light Rail Transit, Highway 407 East Phase 1 and the Rt. Hon. Herb Gray Parkway (formerly the Windsor-Essex Parkway).

Owner’s Role Changes with AFP

AFP Model

Advantages of AFP include:

  • Increased capacity to bring projects to market.
  • Transfer of risk: Appropriate risks are transferred to the private sector to ensure “on time, on budget” delivery and to offer value for money. Design, construction, cost escalation, schedule delays, operations, maintenance, life cycle, and financial risk are all transferred to the private sector.
  • Cost certainty: AFP provides the optimal cost combination, combining capital, maintenance and life cycle costs while integrating design and construction.

Metrolinx's Roles and Responsibilities include:

Design

  • Overall scope (inclusion of maintenance, operations, etc.)
  • Project-specific output specifications (in collaboration with consultant team)
  • Real estate acquisition (in collaboration with the City of Toronto)

Build

  • Oversee construction phase
  • Quality assurance

Finance

  • Manage project budget
  • With Infrastructure Ontario, run a competitive procurement process; select the winning contractor

Maintain

  • Testing & commissioning (in collaboration with the Toronto Transit Commission)
  • Safety certification and project acceptance

Operation

  • TTC to Operate
  • Integration with existing TTC system
