Noise, ground vibration & air emissions are the most common side effects of infrastructure projects

Our experienced team of researchers understand these environmental effects and can provide measurement services and mitigation advice to clients.

Noise, ground vibration and emissions into the air can have a huge negative impact on the people in our communities.

Managing them requires in-depth knowledge of five key, interlinked factors:

  • How the activity generates noise, ground vibrations, or air emissions;
  • How to effectively measure the noise, ground vibrations or air emissions;
  • How the transmission of noise, ground vibrations, or air emissions conveys and influences the effects to the adjacent community;
  • How the community responds to these effects and•How the effects can be meaningfully mitigated, as well as the benefits and costs of that mitigation.

WSP Opus Research's team brings all of these factors together. For example - we have researched how different road surface types affect the levels of road noise generated. A communities response to road noise can directly influence the value of houses adjacent to noisy roads. This knowledge is used to inform national standards or incorporated into policy or guidance documents such as those produced by New Zealand Transport Agency.

The research also provides a strong technical base for providing environmental assessments of specific projects such as new roads or the construction of major infrastructure. As part of these assessments, we regularly provide independent expert evidence to councils, Board of Inquiry or Environment Court hearings
