Powerline Stringing - Dulacca Wind Farm

JWA assisted in connecting the 180MW Dulacca Windfarm, home to Australia's tallest wind turbines standing at 230 metres in height, to the national electricity grid. The project required access and working platforms in sensitive agricultural land and Dura-Base Composite Mats was selected as the cost-effective alternative to traditional crush rock.

Site team installed 560 Dura-Base mats (equivalent to 1.2 km of road) in just one week, saving significant time compared to traditional rock methods, which would have taken 4-5 weeks.

The project made use of 4,700m² of composite mats for temporary roadway and safe work platforms. According to calculations by JWA, considering the standard 300 mm thickness of gravel base typically used for construction access, the utilisation of mats saved approximately 2,818 tons of crushed rock. To put it in perspective, this equates to about 232 loads of 24-ton dump trucks, as opposed to just 22 semi-trailers needed for transporting the mats - both to and from site. This significantly reduces not just the need for quarried material, but also the carbon emissions from transportation.

Using Dura-Base mats helped reduce the resources required, the time and the cost of the delivery of the works package that saw the wind farm being connected to the grid on schedule.
