Rehabilitation of wharves 3 and 4A at the Port of Trois-Rivières

Public Services and Procurement Canada is planning rehabilitation work on Wharves 3 and 4A at the Port of Trois-Rivières. Inspections and engineering assessments have identified various structural deficiencies, including openings between certain concrete sheet piles on Wharf 3, cracks, fractures and localized material loss, as well as an opening in a steel sheet pile on Wharf 4A. These deficiencies may allow the loss of backfill material located behind the structures. Localized seabed depressions have also been identified along the toe of Wharf 3.

The work will primarily consist of strengthening the connection between the concrete sheet piles and the cope wall of Wharf 3, repairing openings, cracks, fractures and deteriorated areas of the sheet piles, and repairing the opening identified in the steel sheet pile at Wharf 4A using a welded steel plate. The localized seabed depressions will be filled with riprap to stabilize the affected areas. In the mean time, public safety features such as ladders, bollards and wheel guards will be replaced.

Concrete repairs will be carried out primarily using anti-washout concrete placed underwater. Riprap required to fill the seabed depressions will be placed from the surface using a crane or equipment mounted on a barge.

Construction is expected to begin in 2027 and will be carried out in close coordination with port users in order to minimize disruptions to ongoing port operations.
