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

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.

6

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 Tunneling 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

10

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

11

Openness through optimal spatial penetration

2. Design that Elevates the Quality of the Public Transit Experience

Optimized daylight penetration

12

Unified ground plane inside and outside stations and at stops

3. Civic Calibre and Scale of Built Form and Materials

Civic materials and character of open spaces

13

Integrated structural, mechanical, and electrical systems

4. Clarity and Simplicity of Architectural Expression through Integrated Building Systems and Elements

A clear hierarchy and plan for user-centred integrated information

14

Integration with historic elements

5. Responsiveness to Contextual, Local and future Conditions

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
