13 Tunnel Fit Out Invert Pour With the completion of the tunnel boring, we now start the next step for work in the tunnels with pouring of concrete slabs to invert or flatten the tunnel floor. This must occur prior to the installation of track and transit systems. Concrete slab to be poured 13

14 Tunnel Fit Out Concrete Pour Overview Concrete trucks deliver concrete every minutes, depending on how far down the tunnel the work is occurring Trucks park beside the shaft at Cedarvale (Allen Rd. and Eglinton), and unload 9 m 3 of concrete into a large pipe, into one of two mini concrete trucks (4.5 m 3 each) at the shaft floor. The mini truck in the shaft then drives down the tunnel to the next section of tunnel to be inverted. The first stage of concrete pour began in tunnel section 1 on April 4, 2017, and tunnel section 2 on April 17, On average, crews complete a section approximately 80 metres in length of the concrete slab per day in each tunnel. 14

15 Tunnel Invert Pour Stage 1 Concrete trucks deliver loose concrete to the work area Loose concrete mix is used to fill the bottom of the tunnel Tunnel Fit Out Crew flatten and smooth it 15

16 Tunnel Invert Pour Stage 2 Workers install welded mesh which functions like rebar to help reinforce the next layer of concrete Higher strength concrete is poured to provide the flat track slab for the rail tracks Workers spread the concrete, and a truss screed machine vibrates it into a perfectly level surface 16
