The Keeyask Generation Project is one of the largest construction projects in the world and a collaborative effort being undertaken by the Keeyask Hydropower Limited Partnership, a partnership between Manitoba Hydro and four partner First Nations.
Located on the Lower Nelson River in the Canadian province of Manitoba – and within the ancestral homeland of the partner First Nations – Keeyask will be a seven-unit hydroelectric generating station that will provide approximately 695 megawatts of capacity and produce an average of 4,400 gigawatt hours of electricity annually. It holds the promise of being a sustainable resource for hydroelectric energy, with enough capacity to power 400,000 homes.
With more than 50 Wood CSA certified concrete materials testing technicians and qualified soil and aggregate lab testing personnel onsite for this complex project, testing the concrete alone was a round-the-clock job. Our experts were onsite 24/7, as large masses of fresh concrete were regularly delivered to placing pumps from an onsite batch plant. Samples collected in the field were then tested for strength in the laboratory.
Tests were performed on 360,000 m³ of concrete structures, the majority of which were cast in place. Materials testing was essential for the success of our customer’s construction schedule, quality control and evaluating the adequacy of curing and protection of all concrete structures, especially the powerhouse and spillway.
Principle structures for the Keeyask Project include: 25 km of dams and dykes, a 7-unit Powerhouse and a 7-bay concrete Spillway with 11,300 m³ of capacity. Wood’s expert inspection and testing enable energy to be securely produced by the Keeyask Generating Station that will be integrated into the hydroelectric system for use in Manitoba, as well as for export.
