EGLINTON CROSSTOWN LRT Next Phase of Construction April 25, 2016
EGLINTON CROSSTOWN LRT
Next Phase of Construction
April 25, 2016
Construction of the Eglinton Crosstown LRT LineBackground
• In September 2008, Metrolinx launched a regional transportation plan – a 25-year, $50 billion plan -- to coordinate and integrate transportation and transit in the Greater Toronto Area
• In 2010, City of Toronto approved the project to build the Eglinton Crosstown from Weston Road in the west to Kennedy Station in the east.
• Following a competitive process, Crosslinx Transit Solutions (CTS) was awarded a contract in July 2015 to design, build, finance, and maintain the Eglinton Crosstown Light Rail Transit (LRT).
Benefits of P3s:
• The Crosstown is being delivered using a public private partnership model called Alternative Financing and Procurement (AFP).
• It was procured as one design-build-finance-maintain project to minimize integration risk – historically, a factor for project cost overruns under traditional models.
• Under the AFP model, CTS assumes most project risks, including:
design, project management and sub-contractor coordination
increases in construction material prices and labour costs
schedule and project completion delays maintenance and lifecycle replacement of
materials within the stations and stops, rails, control systems, and vehicles

Safety First – Our #1 Priority
• Always have a site specific safety plan and site specific emergency plan.• Ensure pre-work hazard assessments are complete and understood.• Ensure job hazards analyses are complete and understood. • Do everything possible to protect themselves, co-workers, and members of
the public.• Stop work if the safety of themselves, co-workers and members of the public
cannot be assured.• Identify and report unsafe behaviour and coach each other to make
improvements.• Be prepared and equipped to work safely.
We train and direct staff to:

Construction Overview
Distinct phases of construction:
• Preparatory works• Utility relocations• Handover of tunnel sections• Support of excavation • Excavation for underground stations• Underground construction of the stations• Track work and systems installation• Traction power system• Signalling system• Testing and commissioning• Road and area restoration
7
Preparing for Stations Construction
Since fall 2015, CTS has been preparing the line for underground stations and stops construction.
Preparatory activities:• Survey and monitor properties for noise and vibrations • Assess soil condition and measure water levels along the corridor• Locate and mark underground utilities• Clearing/grubbing and removing shrubs/trees in the path of the Crosstown• Demolish buildings and other infrastructure (i.e. bridge)• Remove and store street furniture
(i.e. benches, bus shelters, planters, garbage bins)
8
Preparing for Stations Construction
Impacts and mitigations:• Minimal interference to traffic• Limited, day-by-day lane closures• Some overnight work• Access to businesses maintained• Pedestrians have access to sidewalk

What to expect in 2016
10
What to expect in 2016 - Utilities Relocation
• Above and underground utilities will either be relocated and updated before construction begins at a station or occur at the same time as a station’s construction.
• To accommodate stations construction, gas, hydro, watermain and sewer, cable, fibre and telephone lines are relocated.
• Crosstown project is providing upgraded watermains and sewer systems in communities near these stations: – Mount Dennis, Keelesdale, Fairbank, Forest Hill, Chaplin, Eglinton, and
Mount Pleasant.
11
What to expect in 2016 – Handover of TunnelsSpring 2016• Metrolinx transferred security and
maintenance of western tunnel to CTS (runs from Mount Dennis to Cedarvale Stations).
• At handover, CTS inspects the tunnel, reports concerns to be fixed by Metrolinx, and accepts it once the tunnel meets agreed to terms.
• CTS cannot work near a tunnel section until it responsible for it.
• The handover process will take up to two months.
Between June 2016 and 2018• Metrolinx handovers the three
remaining tunnel sections.
12
What to expect in 2016 – Ongoing Design
Features
• About half of the 19 km line is tunneled• Stations and stops are about 0.6 km
apart• Features will include:
• time arrival information• safe access for people walking
and biking to the station • clear route maps, seating, bike
parking • Available parking at the start and end
of the LRT line.
Design Approach
• Comply with nine design principles developed by City of Toronto and Metrolinx.
• Provide a legacy for generations to come. • Have natural lighting during the day and well-lit
entrances at night.• Have safe, clean, intuitive wayfinding at
all the stations and stops.• Put passengers first.• Provide visible entrances, bicycle facilities and
sustainable practices to ensure all stations comply with Toronto Green Standard Tier.
• Landscaped entrances, including planters with trees and ornamental grasses.
• Public plazas and retail components at some stations.
• Clean and minimalist space at platform level.• Accessible to passengers with disabilities, strollers,
and bicycles.
13
• The underground stations run between Weston Road in the west to Laird Street in the east.
• Construction began at Keelesdale station, located at Keele Street /Trethewey Drive and Eglinton Avenue in March 2016.
• Installing support of excavation is the first step in constructing an underground station.
• All underground stations will be brand new, including the three LRT interchange stations connecting to
other transit modes.• Most of the underground stations will be
in construction by the end of 2016.

How we’re building – Cut and Cover Stations
• Twelve underground stations, including interchange stations will use a cut and cover method to support excavation. This construction method entails opening a section of space to allow work below grade. The section is excavated, then covered to allow traffic to flow above.
• To install support (shoring), a crew will:– remove the street pavement on one side of Eglinton Avenue
about 130m x 10m, (the size of two hockey rinks)– A shallow area will be excavated– install steel piles, braces and tie-backs around the sides to support excavation– backfill and cover the pit with a wooden deck on the roadway to allow traffic to
travel across it• After that, the crew moves to the other half of the street to do the same. Installing
shoring and decking is estimated to take approximately 14 months.• Once the shoring is installed, the crew may work under the roadway safely,
excavating to a depth of at least 20m for the construction of the station box. This is where the rail tunnels, associated platforms and rail infrastructure will be housed.
18
Some impacts/mitigations of cut and cover method:
• At least, one lane in each direction will remain open for about 12 months.• Disturbances (noise, vibration, dust, and traffic) will be communicated in advance and monitored.• Side streets near to excavation areas may be closed.• Sidewalks may be rerouted/closed.• Access to businesses will be maintained• Vibration monitors will be installed on properties located near areas being excavated to monitor
noise and vibration levels.• Truck traffic will be routed to well travelled routes.• Where parking spots have been eliminated, on-street, one-hour parking may be relaxed.• Bus stops will be relocated.

• Three stations will be mined and one will be partially mined (Leaside).
• Station entrances will be dug first.• A crew will install support of excavation
around sides of pits (shoring).• They will continue working under the roadway
with minimal impact on traffic.• The excavated area will be lined with
primary concrete “shotcrete” lining (as ground support).
• A station box will be constructed within the lined excavated cavern.
• Once the mechanical, electrical and architectural work starts, the station entrances will be constructed.

Guideways and Tunnel Portals
Guideways• Crosstown has at-grade, underground, and an elevated guideway (rail).
• The elevated guideway is located at the west end of the line.• It consists of a viaduct structure with bridge spans.• Its columns, portals, and retaining walls will be designed to be
aesthetically pleasing.
Portals• Tunnel entrances where the guideway and light rail vehicles will go from
above-ground to underground. • There are two portals: the West Portal, located at Mount Dennis Station
and the East Portal, located west of Sunnybrook Park Station. • Tree groves and grasses will be planted on portals, as well as on station
plazas, open spaces, and stops.
