Deep-water dock construction

We were mandated to build multi-user Dock #35, a deep-water wharf for loading iron ore, located in Sept-Îles.


The mandate included the following work:

  • Building an access ramp (approximately 560 m in length)
  • Building a wharf (400 m in length and 21 m in width)
  • Building a 250-m temporary bridge for a 300 t-capacity crane
  • Drilling and anchoring rock for 88 piles (with a length of ± 55 m and a diameter of 1,829 mm)
  • Drilling and anchoring rock for 42 piles (with lengths of 20 m to 50 m and diameters of 914 mm, 1219 mm and 1524 mm)
  • Installing marine equipment (such as fenders, bollards, capstans and wheel chasers)
  • Building an abutment and installing 35 concrete headers and 64 tie beams weighing more than 90 t
  • Installing 222 NEBT precast concrete beams (with lengths of 20 m and 40 m)
  • Casting in place more than 25,000 m3 of concrete

To complete the project, we partnered with Bermingham Foundation Solutions Inc., an Ontario-based company that specializes in foundation structures.

Thanks to this partnership, effective planning and ingenious work techniques, we were able to complete this mandate on a tight schedule during the winter months.

Our challenge

Hard conditions & tight deadlines

We had to carry out our marine work in a tight timeframe and in the middle of winter.
