Rideau Transit Group (RTG) has informed the City that the results of their root cause investigation and analysis have confirmed that the cause of the roadway collapse was due to unanticipated soil conditions.
Investigative work to inform RTG’s plan for resuming tunneling operations within the tunnel continues.
The following work has been completed:
· The reconnection of the storm and sanitary sewer infrastructure work is now complete;
· Additional borehole investigations were completed in the area; and
· Full access to 50 Laurier has been restored.
A final update will be provided once the City has reviewed RTG’s plan for tunnel commencement at the East Portal.
