  4. 4. 4 Tunnelling Update  TBM 1 is well underway with tunnelling; just recently bored through our west headwall at Keele St.  TBM 2, a twin machine, has been assembled and is following closely behind
  5. 5. 5 Tunnel Drive Sequence 2. Construct Extraction Shaft 1. Construct Tunnel Launch Shaft
  6. 6. 6 Tunnel Drive Sequence Install Jet Grout Block “Headwalls” from Surface Commence Mining Twin Tunnels
  7. 7. 7 Tunnel Drive Sequence Mine-Through Jet Grout Blocks
  8. 8. 8 Tunnel Drive Sequence • Excavate Station and Commence Removing Concrete Tunnel Liners After Tunnel Contract: •Install Station Sidewall and Headwall Support of Excavation Finally: •Station Box Fully Excavated & Tunnel Lining Removed (Not shown)
  9. 9. 9 Launch Shaft Tunnel Boring Machine
  10. 10. 10 Tunnel Drive Works 2013
  11. 11. 11 Tunnel Drive Works Current Status  In 2013 the majority of tunnel works took place between Black Creek Drive and the vicinity of Allen Road  In 2014 work continues east of Allen Road  Crews are starting the construction of headwalls and utility relocation at future station sites along Eglinton Avenue West
  12. 12. 12 Tunnel Drive Works  Headwalls: Temporary support walls for future excavation of the LRT stations.  Made of concrete and installed to the depth of the future track level  Two methods of installation used: Secant Pile Walls, Jet Grout  Machinery including drill rigs, grout tanks, diggers and other equipment
  13. 13. 13 Tunnel Drive Works Secant pile wall : formed by intersecting concrete piles Jet grout wall : uses engineered grout to form wall in situ

  16. 16. 16 Grout Plant for Headwall Construction Why a grout plant at Chaplin? Headwalls for Chaplin required Gilgorm adjacent to work site Gilgorm to remain open one lane northbound Allows efficient use of space Other options examined included Vesta Drive and Eglinton Gilgorm preferred because of: reduced property impact reduced footprint on Eglinton Ave.
  17. 17. 17  The site will be situated on Metrolinx- owned property and occupy City of Toronto roadway  A fence will enclose the site to demarcate the site from the public roadway throughout the entire works  The plant will service headwall construction for Chaplin Station and cross-passages at Vesta Dr and Castle Knock Road  The site is expected to be in place for approximately 8-10 months Grout Plant at Chaplin
  18. 18. 18 Grout Plant at Chaplin Advantages of jet grout technique for headwall installation: Reduce requirement for extensive utility relocation Overall construction time savings
  19. 19. 19 Timeline With appropriate permissions in place Metrolinx’ contractor will: Begin to set up the grout plant Install fencing and secure the perimeter Install grout lines in the roadway Test works Begin Chaplin headwall construction works Chaplin headwall construction is currently scheduled to commence in March 2014 8-10 months anticipated Headwall works at Avenue Road and Bathurst are currently being reviewed
  20. 20. 20 Chaplin Work Staging- South Setup  Work is set up on the south side of Eglinton  The work zone is separated from the ROW with concrete barriers and fencing  Unoccupied traffic lanes remain open on the north side of Eglinton with one lane in each direction  Through-traffic southbound on Chaplin at Eglinton will not be permitted  Southbound traffic must exit at Eglinton or choose an alternate route  Expected duration: Approximately 4 months
  21. 21. 21 Chaplin Work Staging- North Setup  A work site is set up on the north side of Eglinton  The work zone is separated from the ROW with concrete barriers and fencing  Unoccupied traffic lanes remain open on the south side of Eglinton with one lane in each direction  Through-traffic northbound on Chaplin at Eglinton will not be permitted  Northbound traffic must exit at Eglinton or choose an alternate route  Expected duration: Approximately 4 months  Latimer Avenue is closed to/from Eglinton during this phase
