In 2020 Corfield’s Electrical was engaged by Youngs Building Contractors to carry out cathodic protection on the Bridge connecting the plant to South Trees wharf, operated by Queensland Alumina Limited (QAL).
Works include the supply and installation of new cathodic electrical wiring to 5 of 26 concrete headstocks. Due to the concrete delaminating away from the structure due to natural environmental factors over years, the concrete cancer is noticeable and requires replacement.
Corfield’s Electrical are to install cable ladder and control cabling across the length of the bridge allowing access to each headstock junction box. With new structures repaired and poured, Corfield’s will connect the titanium anode material back to the junction boxes using SS conduit as the mechanical protection.
Engagement of this contract followed on from our team’s strong performance on previous cathodic protection work for BMA and Gladstone Ports Corporation.
Corfield’s successfully proposed a number of alternative design solutions that reduced complexity, costs and construction duration. These were critical to the client’s decision to work with Corfield’s Electrical.
