ABOUT THE PROJECT
Wire Sawing and Concrete Removal.
Removal of three 8 metre high concrete pillars using remotely operated Wire Sawing.
We were approached by Iluka Mining who required the installation of a 4m diameter tank for their processing plant with minimal disruption to be caused and on a strict deadline. Before the tank could be installed, three concrete pillars at 8 metres high and 2000mm by 900mm in dimension needed to be safely cut and removed with minimal mess
We identified immediately that most wall saws weren’t going to get through a depth of 900m that easily. There was also the height to consider. To operate a hand saw safely 8 metres high in the air would require additional operators as well as support structures to be constructed, and with limited space and time, this was not an option.
We recommended using a wire saw which utilised a pulley system. This allowed us to make multiple cuts to safely remove the pillars piece by piece, minimising the risk of the concrete pillars falling onto other working areas in process.
All 3 pillars were successfully and safely removed on time in 1 week, with minimal disruption to the worksite and overall work environment.
