PROJECT OVERVIEW
Major Projects Group (CMA Corp) undertook the demolition of the decommissioned incinerator at Port Melbourne. The incinerator was used for ship dunnage, quarantine waste and domestic garbage from the City Council of Port Melbourne.
SCOPE OF WORK
The scope included the demolition, removal and disposal of the decommissioned incinerator at Port Melbourne. The scope also included the removal of all asbestos containing materials. At completion of the initial work, a variation was awarded for the demolition, removal & disposal of approximately 285 m3 of concrete foundations & slabs.
An audit conducted identified asbestos containing materials in the following areas:
-
Fibrous cement sheeting on the ground around the incinerator structure;
-
Fibrous cement sheeting gaskets;
-
Rope lining on door seals;
-
Internal mortar lining between the internal brickwork and the external steel wall.
The audit also identified that paints used on the incinerator were lead based, with a concentration of lead above the maximum allowable in Low Level Contaminated Soil.
CUSTOMIZED SOLUTIONS
To remove asbestos:
-
Encapsulation was built to include all penetrations, using an EWP to gain access to high areas;
-
A skip was placed inside the encapsulation under the hopper;
-
Access was gained to the incinerator via fixed scaffold to enable encapsulation of the access tower; and
-
Asbestos was removed from internal areas of incinerator.
Once the asbestos removal was complete a 35 tonne excavator, fitted with Metal Cutting Shears, was used to cut the incinerator at designed locations to allow the structure to be pulled over with the excavator.
When the incinerator was grounded the excavator processed the steel into small sections to be loaded onto trucks for transport off site.
Upon completion of the demolition the 200mm concrete hob was demolished and removed using a hydraulic hammer mounted on the 35t excavator.
The concrete slab was left in position and the site cleared of any hazards including debris and trip hazards etc. All trip hazards and steel were cut off at the top of concrete slab level using Oxy Cutters.
