Ground Conditions and Boulders
Geotechnical investigations have been completed along the alignment and we anticipate that the ground conditions are favourable for tunneling. However, there is a risk the TBM could encounter harder soil, boulders or soupy sand, which could slow down progress.
Extreme weather, including severe cold, heavy rains, high winds and lightning make working unsafe. During these conditions, the site will be shut down.
Relocation of Existing Utilities
The start date of the project is dependent on relocation of the utilities, including a water main relocation at Worksite #5. There may be some disruption to local services; however, more information will be provided before the work starts.
