The wall consisted of 86 x 600mm-diameter, 10m-deep piles, topped with a cast in-situ concrete capping beam and precast facing panels. The site posed multiple challenges, including limited access, heavy traffic, poor ground conditions, and vibration risks to adjacent structures, including Auckland Transport’s project office.
Our piling approach was key to overcoming these constraints. An EK110 Piling Rig was selected for its compact size, allowing efficient operation in the tight corridor. Piling was completed using a Continuous Flight Auger method, which minimised vibrations, eliminated the need for casings and large craneage, and mitigated risks posed by weak geotechnical conditions.
