B ased in, Queensland, Australia Neumann Contractors has more than 50 years’ experience in contract dredging, with a modern and well maintained dredging fl eet.

Recently Neumann Contractors was involved in the $500 million Port Botany Container Terminal Expansion Project in Sydney, New South Wales. Considered to be one of the largest infrastructure projects of its kind in Australia, the Port Botany development incorporates the expansion of the existing container port terminal to increase port capacity. During their initial involvement in the project, they were contracted to undertake the dredging and reclamation of the concrete casting yard area, access platforms and underwater bunds used for turbidity and environmental control. Neumanns used its 450mm cutter suction dredge the ‘Nu Bounty’, capable of dredging to a depth of 22 metres. The majority of the dredged material came from the new shipping channel, turning basin and berth pocket. As part of the dredging works, Neumann Contractors removed in excess of 1,100,000 cubic metres of sand, which was used for land reclamation within the Port Expansion area. Neumanns was faced with a number of onsite challenges whilst working on this project. In addition to the tight project delivery timeframes, Neumann Contractors also faced unstable and diffi cult weather conditions and the interfacing [Dredging Services] _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ of the dredging with other marine works.

Other projects that Neumann Contractors has completed include the Moura Mine Tailings Dredging to reclaim coal tailings from the Moura 2C pit, for reprocessing to recover the coal fi nes from earlier operations. These works were part of a program to enable ongoing mining underground from the pit fl oor. The Kooragang Berth K5 Dredging project, at the Port of Newcastle, NSW, involved the dredging of 2,600,000m³ of sandy material and 750,000m³ of contaminated fi nes.
