Dredging and Civil Construction Projects throughout Australia

Featured Projects

Kingscoast Estate Project

Resource Mining,
Hydraulic Sand Transfer,
Civil Works.

The project was to hydraulically place 370,000 m3 of sand to raise the surface level of the Kingscoast Estate by 3 metres. The team dredged the sand from an adjacent sand quarry by the Nu Bounty, a 450mm bucketwheel cutter suction dredge combined with a 500mm, 2,000 hp booster pump. The slurry was pumped distances up to 2,000m through a 560mm poly pipeline to the estate. We achieved considerable savings and advantages over traditional methods.

Sydney Water Desalination Project

Capital Works Dredging,
Ports and Harbour,
River and Waterways Dredging.

Dredging works associated with the Botany Bay pipeline crossing, which was part of the construction of Sydney’s DeSal plant at Kurnell, Southern Sydney. When completed water from the desalination plant will be piped to the City Water Tunnel at Erskineville. This is part of the Potts Hill Water system, which services areas south of Sydney Harbour, to Bankstown in the west and Sutherland in the south.

Hellyer Gold Dredge Hire

Dredge Dry Hire,
Mud/Silt/Sediment Removal / Relocation.

Hellyer Gold Mines hired a Neumann Contractors' designed and built 250mm cutter suction dredge, the ‘Nu-Investigator’ for 12 months to supplement the operations of their existing dredge in the site's tailings ponds. The hire agreement was a dry hire arrangement with Neumann Contractors providing experienced operators in the initial phase to train Hellyer’s operators in running the dredge.

Ernest Henry Mine Tailings Dredging

Tailings Removal/Transfer,
Tailings Reprocessing,
Re-Mining.

Ernest Henry Mining commissioned our 300mm CSD Nu Compact to reprocess/remine the tailings from the Tailings Storage Facility (TSF) to recover magnetite. The Nu Compact pumped the reclaimed tailings via a 1000 metre long HDPE pipeline directly into a processing circuit in which the magnetite was concentrated. The dredge operated on a 24/ basis while maintaining a consistent feed density to the processing plant.
