Piling for Wind Turbines
Specialist piling contractor Aarsleff Ground Engineering has completed the installation of 700 No. precast concrete piles for three onshore wind farms in East Anglia, England. Aarsleff drove different sizes and various lengths of piles to support the bases of 22 wind turbines at Deeping St. Nicholas at Spalding, Red House Farm near Holbeach, and Glass Moor near Whittlesey. A French renewable energy company, EdF Energies Nouvelles in association with U.K. wind energy developer, Wind Prospect, developed the wind farms.
The contract to build the wind farm foundation and infrastructure was awarded to Anglo-German turbine manufacturer REpower Systems and U.K. engineering firm Peter Brotherhood. Repower U.K. sublet the civil and electrical works to McNicholas Construction Services, which in turn sub-contracted the £400,000 piling contract to Aarsleff.
“The scheme was originally based on bored piling, but Aarsleff suggested the precast concrete driven pile alternative, which was accepted and incorporated into the design by our designer, Gifford,” says McNicholas project manager, Tony Heaney.
