Rapid Impact Compaction - Woolooware Bay Development NSW

The project proposed a mixed-use residential development over the existing Cronulla Sharks League Club carpark, previously an old landfill site. As part of the works approximately 11,000m 3 of material was required to be removed to enable the development to commence. Due to contamination in the landfill, the client was faced with an expensive disposal if the material could not remain on site. Following site trials, a Rapid Impact Compaction (RIC) machine was engaged to minimise the removal of the contaminated site material.

RIC machines were used to compact the existing landfill material by up to 1.1m removing the need for off-site disposal of this material. The RIC works further improved the existing bearing capacity as part of the compaction process, introducing further potential savings for the client in future piling platform requirements.
