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.
3
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.
4
Eye of the tunnel
The TBM is carefully aligned
with the eye of the tunnel.
The machine will break
through this focal point to start
excavation.
5
Preparing the site
Workers lay track during the assembly
and launch phase.
The pieces of the TBMs are lowered
into the shaft and assembled,
6
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.
7
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.

Crosstown Principles of Design Excellence
1. A strong conceptual narrative vision across the system.
2. Design that elevates the quality of the public transit experience.
3. Civic caliber and scale of built form and materials.
4. Clarity and simplicity of architectural expression through integrated
design of building systems and elements.
5. Responsiveness to contextual, local and future conditions.

1. A Strong Conceptual Narrative Vision across the System
A coherent and unified
architectural strategy for the
entire Crosstown line
Clear strategy for consistent
and variable elements

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
42
New Approach:
Roles and Responsibilities in the Design Build Finance
Maintain model
Metrolinx Role Finance
Design • Project Budget
• With Infrastructure Ontario run a
• Overall scope (inclusion of
competetive prcurement process;
