BlueScope Lysaght ’s Design and Construction business have played a key role in the construction of the first large scale water desalination plant on Australia’s eastern seaboard.

The Gold Coast Desalination Project was initiated by Gold Coast City Council and is now owned by SureSmart Water, whose sole shareholder is the Queensland Government.

The new plant, which is located on a six hectare former landfill site at Tugun and adjacent to the Coolangatta Airport, supply up to 125 megalitres a day of pure drinking water to South East Queensland.

BlueScope Lysaght worked closely with the Gold Coast Desalination Alliance (GCDA) partners and the facility owner to supply, install and warrant an attractive, durable cladding system for ten buildings, which will be constantly exposed to salt laden air in an industrial setting.

The GCD Alliance is an alliance of John Holland, Veolia Water, Sinclair Knight Merz and Cardno.

Chris Johnsson, BlueScope Lysaght’s National Product Manager for PERMALITE worked with the project’s engineers from the outset to develop an appropriate solution for purlins, bridging, cladding and flashing. He worked with GCD Alliance member Sinclair Knight Merz to develop shapes of structural members as part of the cladding package and provided advice on where conventional galvanised purlins could be used.

PERMALITE products are the LYSAGHT solution for aggressive environments where durability, style, economy and good looks are important. PERMALITE products are made from marine grade aluminium, roll formed to produce high performance cladding, or extruded to produce purlins with an exceptional combination of strength and light weight.

BlueScope Lysaght’s Design and Construction team was originally contracted to supply and install purlins and cladding for the Gold Coast plant’s pre-treatment and reverse osmosis buildings and a large pumphouse. This was subsequently expanded to include administration, main sub-station, sludge dewatering, chemical storage, chemical switch building, potable water pump station and gatehouse buildings on the site.

BlueScope Lysaght were able to reduce construction costs for the GCDA by using conventional Z and C purlins with a Z450 zinc coating in appropriate situations. The PERMALITE solution from BlueScope Lysaght ensured cost containment and long-term functionality for the plant.

The Tugun facility buildings have been clad in more than 35,000sqm of PERMALITE wall and roof sheeting in V-RIB and LT7 profiles.

BlueScope Lysaght are also providing a PERMALITE cladding solution for key buildings at the Sydney Desalination Plant which is now under construction.
