Green Piling have recently completed the design, supply and installation of approximately 1000 steel tubular piles at Witney, Oxfordshire.
Two of Green Piling’s Junttan PM20 piling rigs were used to drive the piles within a 6 week period. The piles are to form part of the foundations for a retail, multi-storey car park and residential development in the town centre.
Due to the location of the new development; near the town’s hospital, council offices, library, magistrates court, residential areas and the local police station, noise and vibration had to be taken into account throughout the project. Extensive advanced consultation with the design team and local authorities allayed concerns over the use of driven piles within such a sensitive location. At no time did piling works have to be ceased due to noise or vibration issues.
Steel tubes were offered as the piling system that could not only penetrate the dense and obstructed near surface soils but achieve sufficient penetration into the limestone bedrock interbedded with clay bands to provide high capacities.
177 and 340mm diameter steel tubular piles were driven up to a depth of 12m. Green Piling also undertook rigorous testing of the piles throughout the project; which incorporated 9 static maintained load tests and 90 No. CAPWAP analysis confirming high pile capacities.
