The document summarizes subway closures in 2018 for upgrades to Eglinton station as part of the Eglinton Crosstown LRT project. There will be 24 weekend closures between February and December for station construction including a new subway service building and platform extension. Work will include micro-piling, pre-cast concrete installation, and material delivery and removal using cranes, trucks and construction equipment. The closures will also allow TTC to conduct upgrade work. Noise monitoring will be conducted to mitigate construction impacts.

7. Weekend Subway Closures
• Crosstown Project Agreements requiresCTS to make improvements at Eglinton
subway station
• TTC has approved 24 closures in 2018 for this work
– Subway will close 2am Saturday mornings and re-open Monday mornings at 5am
– Closures necessary because CTS must work on and/or needs access to the subway tracks and
Berwick portal
– Work will occur 24 hours a day during the designated weekend closures
• 2018 closures provide benefits toTTC:
– Construction of new subway service building
– Upgrades/improvements to the subway station
• TTC & CTS coordination to limit overall number of Line 1 closures in 2018:
– During 9 of the 24 closures,TTC will undertake states of Good Repair work
– 15 out of the 24 Closures will be strictly from St Clair to Lawrence

8. Upgrades/Improvements to Subway Station
• During 2018, weekend closures also facilitate upgrades/improvements
to existing subway station:
– Smoke evacuation fans
– New electrical systems
– Improved fire detection systems
– New escalators
• Materials and equipment will be delivered on the subway tracks via the
Berwick portal, necessitating the subway closures
• Additional benefits toTTC/transit users associated with Crosstown
construction:
– Extension of the subway platform by 25 metres
– Upgrading pedestrian tunnels that connect directly to current and future
– development

9. New Subway Station Service Building
• Building will be located over the subway tracks at the Berwick portal
• Provide improved ventilation and life safety systems for existing subway
• Weekend work February – December 2018

12. Description of Construction
• Work will occur day and night on each planned subway closure weekend.
• Three basic phases of work planned: micro-piling, pre-cast installation, and material
supply and removal work:
1. Micro-piling phase (May-July)
– Involves the installation of smaller diameter piles within theTTC subway corridor
– Two micro-pile drill rigs, a mobile crane, and a concrete pump will be used continuously
while concrete and steel deliveries will be intermittent. A hydro-vac may be required
occasionally depending on site conditions.
2. Pre-cast Installation (July-August)
– Involves the delivery and installation of pre-fabricated concrete components
– A 500-tonne crane and various hand tools will be used regularly with intermittent
delivery of pre-cast and concrete grout
3. Material Supply and Removal (September-December)
– Parts of Eglinton Station will need to be demolished and re-built. Berwick Portal will be
used as the access point for nighttime work within the station
– Construction equipment could involve concrete trucks, mobile cranes, and bin trucks

17. Noise Monitoring and Mitigation
• CTS will be assessing sound levels during construction to ensure noise
levels remain within allowable limits and to identify possible mitigation
measures for construction activities.
• Noise mitigation measures already planned include:
– Continuous and proactive noise monitoring from key locations
adjacent the work site
– Acoustic enclosures for pumps and generators
– Broadband backup alarms for equipment
– Environmental awareness training and toolbox talks for contractors
and employees
