|Sydney Harbour Federation Trust
|September 2014 – March 2015
|Description of works:
|Demolition and disposal of 3000 tonnes of concrete decking, including the removal of a large service duct. Removal and disposal of 17 concrete piles, each with a diameter of 1 metre.
Details of any Innovations or extra value for money:
As the site is located in a noise sensitive residential environment, SMC developed a methodology omitting the use of loud rock breakers. This methodology involved wire sawing the concrete decking into large 30 tonne blocks and crushing them onsite using a large pulverising attachment on our 50 tonne excavator.
