BLM was in charge during this project by the client of budget and schedule management, HR coordination, production of deliverables, etc. Underwater inspections were also carried out as well as the work that needed to be done thereafter.

Location

Dock of the Hydro-Québec thermal power plant.

Client

Hydro-Québec

Nature of the mandate

Complete inspection of the dock and its steel components including the entire defence system, replacement and modifications of the latter following the inspection.

Service rendered

• Visual inspection of the structure with simultaneous video recording.
• Comparative assessment of the 2004 overall deficiencies in the steel structure and the defence system.
• Evaluation of the rehabilitation cost.
• Execution of the consolidation work of the steel sections and the components of the defence system.
• Technical reports including rehabilitation plans as built.

Challenges and solutions

The main problem was related to the installation of defence pieces under the water. We had to compensate for the excess buoyancy of the defences by the installation of a system of particular tie rods which had to be adapted for each location. One of the challenges of this contract was to replace the parts while keeping the dock operational.
