ORICA CHLORALKALI PLANT
Sep 06 – Mar 07
Industrial Demolition; and Asbestos & Hazardous Materials Removal
Major Projects Group (CMA Corp) was contracted by Orica to complete the demolition of the Orica Chloralkali Plant. The plant was located in Botany Industrial Park’s fully operational chemical manufacturing site.
SCOPE OF WORK
This Major Projects Group (CMA Corp) project included the demolition, asbestos removal and waste handling necessary for the removal of previously decommissioned and partially demolished Chloralkali plant buildings, plant and a dangerous goods depot at its Botany Industrial Park in Sydney.
The Botany Industrial Park is a fully operational chemical manufacturing site and consideration was required, during demolition, to accommodate the existing traffic movements and the adjacent vibration/shock-sensitive operations.
While the removal and transport of all waste was a separate contract, Major Projects Group (CMA Corp) was responsible for the extraction of the contents from the Dangerous Goods Depot and the demolition of the above and below ground containment structure.
All buildings demolished, with the exception of the Power House, were mercury contaminated, and the waste, considered hazardous, was sent directly to an encapsulated cell.
Due to the shock sensitivity of surrounding operating plants, the material to be collapsed had to be controlled in small volumes each time a section was collapsed.
All steel recovered was required to be washed down, prior to being stockpiled and processed for remelting. In excess of 610 tonnes of metal was removed from the site.
The equipment required for this job included an 80, 40, and 35 tonne excavator with grapple, shears and bucket attachments, a 3.5 tonne forklift, a 66’ EWP knuckle boom and a 50 tonne crane.
The work required a crew of 6 – 9 and was completed with no OHS incidents.
