Tunnel Boring Machine

The construction of new tunnels under Eglinton Avenue is done by tunnel boring machines (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.

4

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.

5

The TBM is carefully aligned with the eye of the tunnel. The machine will break through this focal point to start excavation.

Preparing the site

Workers lay track during the assembly and launch phase

The pieces of the TBMs are lowered into the shaft and assembled

7

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.

8

Tunnelling Begins

Tunnel boring machines work beneath Eglinton Avenue

Business activities and traffic will continue with this method.

A single TBM will tunnel 75 metres per week.

Each machine is capable of moving 500 cubic metres of earth per day.

The machines are made in Toronto by Caterpillar Tunnelling Canada Corporation, formerly LOVAT, a world leader in tunnel boring machine manufacturing.

Owner’s Role Changes with AFP

42

New Approach: Advantages of (AFP) Increased capacity to bring projects to market

Transfer of risk• Appropriate risks transferred to private sector to ensure “on time, on budget” delivery

and offer value for money• Design, construction, cost escalation, schedule delays, operations, maintenance, life

cycle, financial risk

Cost certainty• Optimal cost combination: combines capital, maintenance and life cycle costs• Integration of design and construction

43

New Approach:Roles and Responsibilities in the Design Build Finance Maintain model

Metrolinx Role Design

• Overall scope (inclusion of maintenance, operations, etc.)

• Project-Specific Output Specifications (with Consultant team)

• Real Estate Acquisition (with City of Toronto)

Build• Oversee Construction Phase• Quality Assurance

Finance• Project Budget • With Infrastructure Ontario run a

competetive prcurement process; select the winning contractor

Maintain• Testing & Commissioning (with Toronto

Transit Commission)• Safety Certification and Project

Acceptance TTC to operate

• Integrated with existing TTC system
