Simplex Westpile is on the verge of completing a three month piling project at the All England Lawn Tennis Club in Wimbledon that will create a new basement below two courts and a pedestrian tunnel.
Working in partnership with Galliford Try, the redevelopment work will create space for new restaurants and changing facilities, as well as safer access for visitors.
The basement below courts 14 and 15, which lie between Centre Court and Number One Court, has been formed by 1200mm and 1500mm diameter bearing piles to depths of up to 35m with plunge columns installed in seven of the piles plus a 13m long L-shaped contiguous piled wall formed using 750mm diameter piles.
The pedestrian tunnel has been constructed using cut and cover techniques with rotary bored pile walls formed to 30m depth, two featuring plunge columns. The diameters of these piles varies from 600mm to 1500mm.
