Australia: AFS Bachy Soletanche awarded piling contract for biggest regional infrastructure project
The team at AFS Bachy Soletanche is delighted Roads and Maritime Services has appointed it to deliver piling work for the Glenugie to Ballina bypass section of the Woolgoolga to Ballina Pacific Highway upgrade project.
Roads and Maritime’s Pacific Highway Office and Pacific Complete, comprising Laing O’Rourke and WSP, are working together to deliver the project. The Australian and NSW governments are jointly funding the $4.36 billion upgrade.
Fifteen bridges have already been built as part of the Woolgoolga to Glenugie section of the upgrade, which is expected to open to traffic by the end of this year. AFS Bachy Soletanche won a major piling contract involving installing about 1,100 bored and driven piles for 38 single and 37 twin bridges between the towns of Glenugie and Pimlico. The award of the contract for piling involved engaging industry early in the process to help refine the final design and planning of the work which has helped achieve best value for money for the project.
For the company, the operation consists of installing about 1,100 driven steel piles, bored piles under polymer and bored piles using temporary driven steel tubes for the bridge structures. AFS Bachy Soletanche will be mobilising up to eight rigs for the work, which includes building working platforms, installing piles (including for the Mororo River bridge across the northern arm of the Clarence River) and pile caps.
It can take several days to complete one pile depending on its length and size. They can vary in length depending on the ground conditions and are driven or bored into the ground using a combination of cranes, piling rigs and vibrating hammers.
The company has mobilised quickly to the project to ensure piling is completed in areas where the threatened Oxleyan Pygmy Perch breeds before the start of the breeding season between October and April.
Piling work for other bridges along the alignment will be carried out simultaneously. The bulk of the piling work will be carried out in the next 12 months, weather permitting.
