A combination of dust collection and extraction machines, hired from Kennards Concrete Care, ensured maximum worker safety during the construction of an electricity substation. Fugen Construction are building the zone substation for EnergyAustralia at Kogarah in Sydney. As a part of the project, due for completion late in 2009, the concrete slab had to be scarified so that a topping could be laid.

Following a free site inspection to assess the suitable equipment for the job, Kennards Concrete Care provided two 415V, 10-inch planers, each connected to a heavy-duty, industrial vacuum unit. As an extra measure, a new dust extractor was also recommended. These units, which operate on 240V 10A power, have a fan that is 500mm in diameter, and produce a flow capacity of 6800cfm. They can be used with or without a sock attachment. The sock, which was used to advantage at the substation, is 7m long and 1.2m in diameter when inflated. Zippers allow the contents to be emptied and the sock washed.

According to Robert Zukowski, Foreman, Fugen Constructions, between the different types of machines, they got an environment that was virtually dust free. The new topping on the concrete slab was needed because of the electrical machinery to be used in the substation. The machinery will be quite big and on uni struts, so the slab has to have a plus or minus tolerance of 1mm over 3m. This is unachievable with standard concrete so they had to do a topping slab, 32MPa to 90MPa in various areas and 65mm thick.

Kennards Concrete Care have outlets in Sydney, Brisbane, Melbourne and Perth.
