Five new wind turbines with capacity to power 14,000 homes are now being erected by main contractor Forkers in East Yorkshire following successful completion of the piled foundations.
Work on RES’s new Roos Wind Farm near Hull started in June this year and is expected to be completed by summer 2013.
Simplex Westpile has just completed construction of 122 CFA piles to support the turbines and a meteorological mast at the site. The foundation solution for the project used a mix of 92 600mm diameter piles and 30 750mm diameter piles constructed to depths varying from 25 to 30m.
Construction was not straightforward and the site required ground improvement before the main piling and construction work could get underway. Vibro Menard installed 5000 320mm diameter controlled modulus columns at 1.2m centres to depths of between 7 and 21m in order to create a 200kPa capacity working platform for cranes to operate at the site.
