In a project that ran from May 2009 to February 2012, the specialists at Thiess Services were awarded the contract to revitalize the Hunter River bed, which for over 70 years was contaminated by pollutants deposited there by a steel plant. In the first phase, the CIMIC company excavated 800,000 cubic meters of contaminated soil from the river bed—enough to fill 300 Olympic-sized swimming pools. They then decontaminated and disposed of the sediment professionally. Thanks to the revitalization, the former industrial site in Newcastle can now be put to good use. This revitalization project, the largest of its kind ever undertaken in Australia, received the United Nations Association of Australia World Environment Day 2011 Award in the Environmental Best Practice Program category.
