WHAT’S YOUR PROJECT...?

Dams

Hydro-Québec and other owners of dams frequently call upon the expertise of Queformat when building new structures or repairing existing ones. Recently, Queformat has participated in a number of projects, including:

• Building the EM1 power station and LE24 dike, traversed by a lake and lying on compactible soil;
• Conducting behaviour studies of the OA11 dam and tributary weirs;
• Re-building the Pont-Arnaud dam, destroyed in the Saguenay flood of July 1996, in design-build mode;
• Building the EM1-4 power station, diverting the Rupert River and designing the PK-85 and PK-110  weirs for the river;
• Repairing the Farnham dam and securing the left bank of the same river;
• Conducting geotechnical studies in preparation for new developments in Nunavik, on the Caniapiscau and Nastapoka rivers;
• Carrying out rehabilitation studies for the Machu Picchu power station in Peru;
• Conducting design and construction studies for dikes for a mining project in Mali.
