The scope of works included:
Our custom designed, in-house demolition works programme was the first of its kind in Australia and involved a partnership with MB-Abbruchtechnik to fabricate specialised machinery that could deconstruct the stack ‘top-down’ whilst achieving strict emissions, noise and vibration controls. Our solution centered on a shear with a kibble slung from a tower crane attached to the side of the stack and dropping all debris into the kibble or down the centre of the stack.
The second stage of our programme involved an induced collapse of the boiler house structure following the safe removal of large volumes of friable asbestos. Our programme design also took into consideration an adjacent turbine hall structure that was protected by a temporary framework of steel columns and cross-braces as well as concrete footings. The computer modelling and simulation techniques we adopted allowed us to predict how the structure would behave in the initial stationary position and throughout the induced collapse.
Following a successful ‘drop’ we processed and recycled more than 3,000t of construction waste materials before undertaking the remediation and rehabilitation of contaminated soil:
