Aarsleff Ground Engineering has announced that it has been appointed to undertake the piling work for the new Stadium Leisure Complex in York by Buckingham Goup on behalf of clients Greenwich Leisure and Wrenbridge Sport York.
Early engagement on the scheme saw Aarsleff work with Arup to refine the design from a continuous flight auger solution to use of driven precast piles to add efficiency to the on site work.
“Essentially, at an early stage we proposed a series a load capacities for our different pile section sizes and the client’s engineer took these on board to enable them to switch to a driven pre-cast approach,” said Aarsleff foundations estimator Euan Allison. “The piles we are installing are a range of lengths and sizes, mostly though firm to stiff clay strengthening linearly with depth, overlying dense sand at 12m depth.
“The client recognised early on in the design process that driven precast piles would enable a cost-effective solution to be pursued and this early engagement allowed the tailoring of the piling project to suit our low factor of safety/cost offerings.”
Aarsleff has now started work on installing the 925 piles for the new complex that will combine sport, health and educational facilities includes an 8,000 all seater stadium to be shared by York City Football Club and York City Knights Rugby League Club.
Three Junttan piling rigs are working to install the 250mm diameter piles which vary in length between 9m and 14m.
Work on site is expected to be completed before the end of this month.
