USX (Uranium Extraction) Enhancement Plant, SA

Duration: May 2002 to March 2003

Value: $28 million

Contract type: Fixed Lump Sum, Schedule of Rates, Hourly Hire

Summary: Built Environs completed this uranium process plant mechanical installation works package for Western Mining Corporation (WMC) to replace an earlier fire-damaged plant.

This complex mechanical installation was made all the more challenging by a compressed fast-track programme and a range of responsibilities for the supply of materials.

The design continued to evolve as construction progressed, requiring extraordinary site management and supervision, quality control and administration.

The project included installation of 24 km of small bore to 700-mm pipework in a range of high-performance materials, as well as mechanical services, underground drainage and scuttle lines.

When the installation works were completed, key Built Environs staff and employees remained on the project until the successful commissioning of the plant.

The works were safely carried out within the operational plant in a radioactive environment and among open ponds of volatile kerosene and other process liquors.

The Built Environs engineering capability that delivered this project is now provided by the South Australian engineering office of parent company McConnell Dowell, offering clients access to both the expertise of the former Built Environs engineering teams and the international experience of McConnell Dowell.
