Adelaide Brighton Cement
July 01 – Oct 04
Industrial Demolition & Deconstruction; Asbestos & Hazardous Materials Removal; and Remediation
Adelaide Brighton Cement engaged Major Projects Group as a principal contractor to undertake the staged demolition of the entire former Geelong cement works.
SCOPE OF WORK
The scope of works for this Major Projects Group project was for the complete removal of all asbestos, the demolition of all buildings, conveyors and structures to 1.2 metres below natural ground level and the remediation of an estimated 33,000 tonnes of soil contaminated with organics and heavy metals. The project was conducted in 2 phases over a 3 year period.
Hazardous material removal
Use of explosives for the demolition of stacks.
Provision was made for the demolition off site of the overland conveyor system and works within the Batesford Quarry area. Conveyor systems were removed both manually and mechanically, and taken off site for processing. At the completion of the works, the site was left in a clean and tidy condition.
3 concrete chimney stacks, 2 measuring 106.68 metres and one measuring 97.53 metres in height, were demolished as part of the scope.
The total weight of concrete and bricks in these 3 stacks was 6000 tonnes.
Major structures on this site were dismantled from the ground with a 160 tonne excavator equipped with an MSD 140R rotating shear as a third arm member. Lesser structures were demolished using two 70 tonne excavators.
A smaller 22 tonne excavator fitted with an MSD40R rotating shear was used to process structures once on the ground. Other equipment included a 140R rotary shear attachment and a CP120 concrete pulverising attachment. Three levels of remediation were employed at the completion of this project, remediation by in-situ landfarming, remediation by excavation to low level landfill, and remediation by excavation to high level landfill. The project scope also included the lifting and removal of rail tracks, whilst asbestos removal commenced, on the lesser structures.
2,563 tonnes of steel were removed from site for recycling and an estimated 33,000 tonnes of soil, contaminated with organics and heavy metals, was remediated.
