BC Hydro awards $1.2bn contracts for Site C hydroelectric dam

CTBR Staff Writer Published 19 March 2018

Canadian electric utility BC Hydro has awarded three contracts valued at C$1.6bn ($1.21bn) to complete its Site C hydropower project in Canada.

The contracts have been awarded to Aecon-Flatiron-Dragados-EBC Partnership (AFDE Partnership) for the generating station and spillways civil works components of the Site C project.

The AFDE Partnership includes Aecon Constructors, a division of Aecon Construction Group (Aecon), Flatiron Constructors Canada (Flatiron), Dragados Canada (Dragados), and EBC.

The company said that the contract, which is the second largest for the project, falls within the revised project budget of $10.7bn ($8.1bn).

The contract includes the delivery of civil works associated with the powerhouse, penstocks, spillways and power intakes.

Under the the generating station and spillways civil works, placement of about 700,000 cubic meters of mass and reinforced concrete will be carried out and a 34,000 tonnes of rebar will be installed. 

The contract will also cover the construction of the two spillways that are 17-storeys high and five highway-lanes wide.

During the peak of construction in 2021, the project is expected to see 1,600 people working on the generating station and spillways civil works. 

The contract is scheduled to be completed over a five-year period after the contractor mobilizes on site in spring 2018. 

The other two contracts that were awarded include a C$33m ($25.1m) contract to build the Site C substation. The contract awarded to Nanaimo-based F&M Installations.

The second contract, which is worth C$23m ($17.5m) was awarded to REEL COH. It includes the design, supply and commissioning of the generating station and spillways powerhouse bridge and grantry cranes.

Site C is a hydroelectric project which will be constructed on Peace River near Fort St. John in British Columbia, Canada. The site will have a capacity to generate 1.1GW of clean and renewable electricity annually.
