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
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

Secant pile wall : formed by
intersecting concrete piles
Jet grout wall : uses engineered
grout to form wall in situ

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
 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
