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

it has placed behind it to line the tunnel

• 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

Mount Pleasant Headwall Construction

Possible Jet Grout

Plant location

9

Jet Grout Rig

Jet grout rigs will be

used for headwall

construction at

future stations and

the extraction shaft

at Yonge Street

10

Jet Grout Plant - Sutherland / Donlea

Jet Grout rigs will be used for headwall construction at future stations, cross-passages and

emergency exits.

11

Timeline for Mount Pleasant Headwall Works

With appropriate permissions in place, Metrolinx’ contractor will:

• Conduct some utility relocation before headwall construction

• Install fencing and secure the perimeter

• Install grout lines in the roadway

• Jet grout plant will be set up prior to the headwall

construction

• Begin Mount Pleasant headwall construction in late Summer

2015

• Approximately 4-6 months anticipated at each wall

Mt Pleasant Station Emergency Ventilation Shafts

• East emergency ventilation shafts will be

combined with the Secondary Entrance building

• West emergency ventilation shafts will be a

stand alone structure in the Brownlow Avenue

boulevard

• Further analysis and detailed design will be

completed by Project Co

Property Requirements

• Part 1 – Construction

and maintenance access

for ventilation shaft

(permanent easement)

• Part 2 – Ventilation shaft

equipment below grade

(fee simple subsurface)

• Part 3 – Construction

Staging (temporary)

Property Requirements

• Part 1 – Construction

for ventilation shaft

(permanent easement)

• Part 2 – Ventilation shaft

equipment below grade

(fee simple subsurface)

• Part 3 – Construction

Staging (temporary)

24

Property Requirements

• TDSB has been engaged on the property

requirements and discussions have been on-going

with Metrolinx.

• Commencement date for permanent and temporary

requirements is October 15, 2015.

• Duration is 4 years, plus an option to renew for 1

additional year.

25

TDSB Proposed Alternative

• TDSB proposed an

alternative vent shaft

location

• Vent shaft would be on

TDSB property instead of

City property (shift from blue

area to red area on drawing)

• Intent to reduce construction

impacts to parking area and

site operations

26

Evaluation of TDSB Proposed Alternative

• Vent shaft location proposed by TDSB – Pros:

– Closer to the station box

– Could result in less disruption during construction

• Vent shaft location proposed by TDSB – Cons:

– Vent shaft is more visible adjacent to the school and fronting on Eglinton

– Vent shaft is closer to openings in the school buildings. The vent shaft must be a

minimum of 12 metres (horizontal distance) from any operable windows or 2.5 metres

above any operable windows.

– Will cause permanent reduction in TDSB staff parking area

– Depending on height of the vent shaft, it could block sightlines for service vehicles

entering and exiting the loading area

– Could cause impacts to the existing school structure/ foundations

– The work zone, including cranes and other large machinery, would be closer to the

school

27

Evaluation of TDSB Proposed Alternative

• Based on preliminary design and engineering by

Metrolinx, the Brownlow boulevard was determined

to be the best location from a technical perspective

• The vent shaft location proposed by TDSB will not

eliminate disruption to normal parking, garbage and

deliveries during construction

• In the long term, the current vent shaft location

selected by Metrolinx is better for TDSB as it does

not permanently affect parking, garbage or delivery

operations

28

Roles and Responsibilities

• Metrolinx is managing the construction project.

• City reviews Metrolinx proposals for interim traffic control

measures during construction.

• Toronto Police, City Transportation and Metrolinx meet

regularly to discuss issues and project needs such as

enforcement, traffic management and parking.

• City is responsible for approving any temporary and

permanent changes to turn restrictions, traffic calming,

etc.

29

Our Approach to Traffic Management

• Maintain a minimum of one lane eastbound and

westbound on Eglinton in construction work zones

• Buses and general traffic will share this lane

• Additional lanes will be provided if space allows

• Metrolinx will work with City of Toronto Transportation,

local elected officials and neighbours to monitor local

traffic

• Signal timing may be modified and turning restrictions

may be added or relaxed to improve the flow

30

Traffic Lane Reductions

Temporary road closure,

local traffic only

Traffic reduced to one lane

in each direction

Proper City permitted traffic signage will be installed

31

Transit Services during Tunnel Construction

• Both eastbound and westbound TTC stops in the

affected area may be shifted and relocated for the

safety of transit riders

• Watch for TTC posted signs indicating the adjusted

stop locations

32

Pedestrians

• In the construction zone, for temporary sidewalks or

existing sidewalks the goal is to maintain minimum

1.5 metre sidewalk widths wherever possible

• Access to properties from sidewalks should be

maintained

• Some sections of sidewalk may be closed and

crossings will be available at traffic signals

• Please take care when travelling near construction.

Watch for additional signage directing pedestrians

33

Pedestrian Detours

Sign directing pedestrians Temporary detour of

pedestrian sidewalks may

be required
