John Holland has been awarded a contract for structural mechincal and piping construction works at the Worsley Efficiency and Growth (E&G) Alumina Refinery project in Western Australia.

The Area 1 mechanical and piping works will increase the alumina refinery capacity by over 30 per cent, from 3.5 to 4.6 million tonnes per annum. The contract will involve construction of new processing facilities for bauxite blending and storage, calcination, filtration, classification and alumina handling. Process piping works and modifications to the site’s existing precipitation facility will also be undertaken as part of the works.

John Holland’s scope of work includes pre-assembly and installation of 6000 tonnes of structural steel, 56,000 metres of piping and 200 tonnes of bulk mechanical items.

The major mechanical and piping installation package for Worsley’s E&G Project follows the contract win on the Yarwun 2 Alumina Refinery project in Queensland.
