Concrete In Australia : March 2012
10 Concrete in Australia Vol 38 No 1 NEWS Concrete caisson site visit for summer school A site visit to the concrete caissons being constructed for Chevron s Gorgon project by the Saipem Leighton Consortium at Henderson, Western Australia, was a highlight within the Indigenous Engineering Summer School held in Perth in January. e Saipem Leighton Consortium is contracted to develop the $900 million Gorgon LNG Jetty and Marine Structures project. e jetty will consist of steel trusses 70m long supported by caissons which lead to the loading platform approximately 4km from the shore. e design uses 56 concrete caissons which are being manufactured at the Australian Marine Complex in Henderson. At the caisson fabrication facility, the Indigenous high school students saw form workers, steel fixers, scaffolders, plant operators, concrete workers, general labourers, project engineers, site engineers, surveyors, general foreman and supervisors. e students converged on Perth from around Australia in January for the summer school, which was held at Curtin University. A summer school was also held in NSW at the University of Sydney. Established in 1998 by Engineering Aid Australia, the week-long live-in summer schools introduce Year 11 and 12 Indigenous students to engineering and the wide range of opportunities an engineering degree offers. At Curtin University, 16 students took part in activities including making and test-loading paddle-pop stick bridges, assembling light-beam sensing circuits, assembling and controlling miniature robots, pumping water with energy from photovoltaic panels and driving fans with electricity from hydrogen cells. In Sydney, students visited the Leighton M2 widening project and the RMS (formerly the RTA) model road and tunnel construction site. Industrial vacuum cleaners delivered to caisson site e Saipem Leighton Consortium complex at Henderson, Western Australia, has taken delivery of two Big Brute wet and dry industrial vacuum cleaners for cleaning the concrete caissons. Concrete supervisor Joe Strangio first contacted Big Brute to ask for a hands-on onsite demonstration of the industrial vacuums after he found other vacuums struggling in the fine cement dust environment. In the demonstration Strangio suggested trying the vacuums on fine concrete dust that had been ground off the caissons prior to placing the next layer of concrete. After trialling the vacuums for twelve weeks at the Henderson complex, the consortium placed an order for two. Students gather at the graduation dinner with Curtin University vice-chancellor Professor Jeanette Hackett, federal MP Ken Wyatt and the Western Australian chief scientist Professor Lyn Beazley.
