Launch of the State highway guide to acoustic treatment of buildings.
Highways and Network Operations’ Environment and Urban Design team have launched the new State highway guide to acoustic treatment of buildings.
Noise mitigation provided by the NZ Transport Agency is always used within the road corridor where practicable, using low-noise road surfaces and noise barriers. If those measures are not practicable then the acoustic treatment of buildings, such as the provision of mechanical ventilation so that windows can be left closed, may be offered to residents where required by NZS 6806.
This guide has been produced to inform the Transport Agency staff and contractors about factors involved in the selection, design and installation of acoustic treatment of buildings.
The Transport Agency has not previously provided guidance in this area so when buildings have been acoustically treated various different processes and treatments have been used. All works should now be conducted in accordance with the standard processes set out in the new guide. In terms of treatments, new specifications in the guide require ventilation systems to be installed generally with higher air flow rates than previously used and with cooling.
