VolkerGround Engineering completed the installation of steel sheet piles to form the split level car park basement of a new apartment block in Durham.
At the commencement the pile line was pre augered to assist with the installation. As the site was situated between two office buildings we installed the piles using our resonance free leader rig to minimise vibrations. An impact hammer was then mobilised to drive the piles down to the required toe level.
Once installation was complete the clutches were welded to form a watertight seal. The retained height of the basement was in excess of four metres and ground conditions would not allow a cantilever option. Therefore, a hydraulic frame system was installed until the basement and floor slabs were cast. This contract was completed on programme and within the agreed budget.
