Construction of a new dock

Our team was awarded the contract to build the new cruise ship dock in Sept-Îles, accommodating cruise ships on the St. Lawrence River.


More specifically, the mandate involved the following:

  • Building the main dock in reinforced concrete on 120 tubular steel-driven piles and three mooring dolphins, which were also supported by tubular steel-driven piles (35 units)
  • Supplying and installing all berthing elements (fenders and mooring bollards)
  • Designing, supplying and installing steel sleeves on piles (ice damage protection)
  • Installing a water main
  • Installing electrical facilities for future needs
  • Paving the access road to the new dock
  • Restoring the existing wharf, including demolition, concreting and riprap work to secure the sides of the wharf
  • Dredging 46,000 m3 of the seabed to allow vessels to berth at the new wharf.

The project was a huge success — we completed it two months before the contract end date and saved more than 10% of the structure cost with precast concrete.

Our challenges

Precision work

From the barges, we placed the piles with a tolerance of only 100 mm and the precast elements with an accuracy of within one centimetre.


Harsh natural conditions

We had to deal with the natural elements of the location, such as wind, waves and high or low tide to perform certain tasks.


Prioritizing marine preservation

We worked efficiently, all the while protecting marine life—for example, complying with restrictions during the installation of the piles.
