Driving of precast concrete piles and steel piles for the new Wales National Swimming Pool in Swansea.
Shepherd Construction awarded Aarsleff Ground Engineering the piling contract for the new Olympic size Wales National Swimming Pool in Swansea. The swimming pool complex, constructed for the City and County of Swansea, includes a 50m main pool and a 25m practice pool, and is located within Swansea University’s existing sports compound.
Aarsleff started piling late March in 2001, driving just under 560 No. 300mm square, single and jointed precast concrete piles from 11m to 18m long through about 6m of fill and underlying dense gravel. However, Aarlseff’s Banut 500 piling rig, with a 5t Uddcombe drop hammer, ran into difficulties with occasional piles refusing and breaking. It was expected that some of the precast concrete piles might be difficult to drive through the stiff made ground with obstructions, prompting a reassessment of the piling operation.Download Case Study
