The removal of a redundant iron ore smelting facility in Kwinana, Western Australia. Innovative asset and resource recovery solutions saw 108,000 tonnes of material recovered.
The project involved the dismantling and relocation of almost half of the Hlsmelt plant, comprising more than 7000 tonnes of industrial plant and equipment which was salvaged and shipped to China. More than 2000 bulk units were methodically dismantled, cleaned to export standard, match marked, labelled, recorded and packed to allow for reassembly in China.
Significant structures demolished included the 75 metre high Preheater and the 65 metre high Off-Gas Hood structure. Both were collapsed using controlled cut and pull demolition techniques whereby engineered prewekening and inertia is utilised to bring taller structures to ground level for mechanical processing.
Sustainability was a key feature of the project. In addition to the 7,000 tonnes of plant and equipment items salvaged, 12,000 tonnes of scrap metal was recycled and Liberty Industrial found resourceful solutions to dispose of 25,000 tonnes of concrete and waste products from the smelting process including 50,000 tonnes of slag, 7,500 tonnes of dolomite and 5,000 tonnes of iron skulls.
The project was awarded the Industrial Demolition and the overall World Demolition Award at the 2014 World Demolition Awards.
