Midtown Hydro Project Update

Hello everyone,


I wanted to provide you with an update on the Midtown Project. Tunnel excavation has been progressing very well, and Technicore expects that the tunnel boring machine (TBM) will reach the shaft later today, or tomorrow. When the TBM breaks through the tunnel and into the shaft, residents will hear a significant increase in noise at that moment. Please don’t be alarmed if you hear a loud banging noise.


Next week, the TBM will be removed from the shaft, and travel on a flatbed truck along the construction access on Old Pottery Road to Bayview Ave, where it will travel to the main shaft at the Rosehill pumping station.

Over the next several weeks Techniore will be preparing the site so that the tunnel can be lined with concrete and the freeze plant equipment will be removed. Once the work to line the tunnel begins, residents will notice concrete trucks travelling to and from the site. We expect that this will be similar traffic as earlier this year, when Technicore was pouring concrete for the shaft.
