Residential Excavation Shoring

Austral were contracted by Mainland Civil to supply and drive approximately 2800m2 of 5m to 12m sheet piles.The project had been fast-tracked.

Initially the design concept was contiguous bored holes however economic benefits were found to result from converting a large portion of the excavation shoring to sheet piling.

Timing did not permit placement of an order from overseas mills and material was sourced locally from Steelcom. Careful management resulted in deliveries of various lengths and to balance the “shorts and longs” thus minimising waste and avoiding splicing off-cuts.

The topography of the site was one of the most difficult Austral had worked on, however Austral are in the fortunate position of having a dedicated sheet piling rig, unique in Australia. The ABI Mobilram rig, capable of pitching and driving sheets to 14m was ideally suited to the task and achieved good production, in spite of the difficult conditions, not least of which was the dense sand.
