Modular wall exceeds infrastructure noise wall requirements in Queensland
13 January 2017
This master-planned community in the Queensland town of Cooroy is situated adjacent to the Bruce Highway – the largest carrier of traffic in the Sunshine State. Its roadside location necessitated the erection of a highly effective civil noise wall in order to insulate residents of the development from the constant drone of the highway.
In addition to serving as a strong buffer against copious amounts of acoustic pollution, the wall also had to satisfy the requirements of a civil infrastructure wall as opposed to just a road or railway noise barrier. Installation itself posed a challenge given that the terrain of the development is not flat or level, and the noise barrier itself is situated on top of a sloping landscape mound.
The client opted to use the GuardianWall in combination with our EnduroMax panel to create a 287 metre noise barrier that fully satisfies civil infrastructure requirements as well as protects residents from the acoustic pollution of the highway. The GuardianWall consists of galvanised steel beams that have a +50 year design life.
The EnduroMax panel is an impact resistant product which is approved by the Queensland Department of Transport and Main Roads, enhanced the durability of the wall by enabling it to better withstand any bumps or flying debris. The lightweight, modular nature of the product greatly facilitated the installation of the noise barrier, particularly given the variable terrain of the development which meant that the height of the wall varied from 1.1 to 3.4 metres.
