In June 2012, Bermingham Foundation Solutions Limited was retained by H.B. White Canada Corp. (an EPC contractor) to supply and install foundations for 55 wind turbine towers for the East Lake St. Clair Wind Farm project. The turbines, to be spread over a 110 square kilometers area of privately owned farmlands in the Chatham-Kent region, are to provide a total of 99 Megawatts of power upon completion (enough energy to power nearly 55,000 Canadian homes each year); anticipated completion date was set for August 2013.
With the project came several unique challenges, none more so than soft earth conditions and wet, marsh-like surroundings. As specified by the contract, piles were driven in a circular configuration on a 1:4 fore batter alignment. In total 1,500 bearing H-piles, with varying lengths from 17 to 29 meters, were driven to refusal at or near the underlying shale bedrock. As a testament to Bermingham, the project was completed on time within the aggressive four-month scheduled period. At peak production, four cranes equipped with Bermingham Vertical Travel Lead Systems and B-32 Direct Drive Diesel Pile Driving Hammers were utilized to install piles from within the pile ring at the underside of the pile cap elevation. Despite soft soil conditions and restricted confines of the foundation limits, production rates were effectively maintained and peaked at 50 piles in one day. As proud supporters of clean energy Bermingham was pleased to work in conjunctions with H.B. White to help bring renewable energy to Canadian families.
