A presentation shown at the Open Houses on September 10 and 11 to show what is happening, why it needs to happen and how it may impact the community.

1. CROSSTOWN CONSTRUCTION UPDATE FALL 2014
Welcome to the Open House

2. Eglinton Crosstown LRT
•Project
–$5.4 B (2010$), funded by the Province of Ontario
–19 kilometres east-west LRT from Kennedy to Jane/Black Creek, including 10 kilometers of tunnel
–Connections to Yonge-University-Spadina Subway, Scarborough RT and GO Stouffville
–Up to 26 stations

3. Tunnelling Works 2014-2016

4. Construction Timeline
•At future station locations underground structures (emergency exits, cross passages) utility relocation and headwall installation are expected to last approximately six to eight months on average
•When the TBMs reach Eglinton West Station, they will be extracted using a shaft located just west of Allen Road.
•The TBMs will be refurbished and re-launched just east of Allen Road, for the second phase of tunnelling to Yonge Street.
•Tunnelling activities to Yonge are expected to be completed by December 2016
•Following the completion of tunnelling works, the sites will be turned over to the Metrolinx station contractor in two phases; west of Allen Road (2014) Allen Road to Yonge (2015)
•Station construction expected to begin Spring/Summer 2015

5. Tunnel Drive Works 2014
•Headwalls are temporary support walls for future excavation of the LRT stations.
•Made of concrete and installed to the depth of the future track level
•Jet Grout method of installation will be used on headwalls east of Allen Road
•Machinery including drill rigs, grout tanks, excavators and other equipment

6. Tunnel Drive Sequence
Construct Extraction Shaft
Construct Tunnel Launch Shaft

7. Tunnel Drive Sequence
Install Jet Grout Block “Headwalls” from Street Level
Commence Mining Twin Tunnels

8. Tunnel Drive Sequence
Mine Through Jet Grout Blocks and Tunnel to Extraction Shaft

9. Station Construction
After Tunnel Contract:
•Install Station Sidewall and Headwall
•Excavate to Tunnel, Remove Concrete Tunnel Liners and Begin Station Construction

10. Tunnel Boring Machines
•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

11. Launch Shaft Tunnel Boring Machine

12. Tunnel Drive Works Current Status
•In 2013 the majority of the tunnel drive and associated works took place between Black Creek Drive and the vicinity of Allen Road
•In 2014 work continues east of Allen Road
•Crews continue the construction of headwalls and utility relocation at future station sites along Eglinton Avenue West
•TBM 1 is well underway with tunnelling; TBM 1 is now located west of Oakwood Avenue
•TBM 2, a twin machine is following closely behind

13. Jet Grout Headwalls

14. Jet Grout Drill Rig

15. Grout Plant for Headwall Construction
Why a grout plant at Peveril Hill North?
•Headwalls for Bathurst required
•Peveril Hill North adjacent to work site
•There will be no access to/from Eglinton Avenue West at Peveril Hill North
•Peveril Hill North between Dewbourne Avenue and Eglinton Avenue will be local access only
•Allows efficient use of space
•Peveril Hill North preferred because of reduced footprint on Eglinton Avenue

16. The site will occupy City of Toronto roadway
The plant will be located on Peveril Hill N requiring closure of the street at Eglinton
A fence will enclose the site
The plant will service headwall construction for Bathurst Station on the north and south sides of the street
The plant is expected to be in place for approximately 6 months
Grout Plant at Peveril Hill N

17. Jet Grout
Advantages of jet grout technique for headwall installation:
Reduce requirement for extensive utility relocation
Overall construction time savings

18. Timeline for Bathurst Headwall Works
With appropriate permissions in place Metrolinx’ contractor will:
•Begin to set up the grout plant at Peveril Hill N.
•Install fencing and secure the perimeter
•Install grout lines in the roadway
•Test works
•Begin Bathurst headwall construction works
•Scheduled to commence in September 2014
•6 months anticipated

19. Timeline for Avenue Headwall Works
With appropriate permissions in place Metrolinx’ contractor will:
•Begin to set up the grout plant at Highbourne Avenue
•Install fencing and secure the perimeter
•Install grout lines in the roadway
•Test works
•Begin Avenue Road headwalls in Fall 2014
•6 months anticipated at each wall

20. Utility Relocations
•Depending on site conditions: gas, hydro, water mains, sewers, lighting and telephone and cable lines may be relocated to allow for construction
•In the vicinity of the launch and extraction shafts Metrolinx is co-ordinating with Bell, Enbridge, Toronto Water, Toronto Hydro and Cogeco regarding required relocations
•In most cases utility relocations will be undertaken by Metrolinx contractor
•Enbridge will coordinate works with Metrolinx

21. Bathurst Headwall Locations

22. Avenue Headwall Locations

23. 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

24. Emergency Exit Buildings and Cross Passages
•Cross passage and emergency exit construction will take place between late 2014 through late 2016

25. 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
•Metrolinx coordinates with TTC for service adjustments required due to construction. TTC is responsible for bus detours and rerouting

26. Cross Passages
•A cross passage is a tunnel connecting the eastbound and westbound tunnels for maintenance and/or emergency purposes
•Crews will be building cross passages before and after the tunnels are complete
•Some construction works will be visible at street level while other works take place underground

27. Pedestrians
•In the construction zone for temporary sidewalks or existing sidewalks the goal is to maintain 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

28. Next Steps
•Community Relations will outreach to businesses, specific condos and apartment buildings to raise awareness of the site and planned works
•Co-ordination with TTC will continue to ensure continued bus service
•Co-ordination with local emergency services also continues to ensure service levels
