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

Our experienced team researches these environmental effects and provides measurement services and mitigation advice to clients.

Managing environmental effects 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 impacts the community
  • How the community responds to these effects
  • How the effects can be meaningfully mitigated, as well as the benefits and costs of that mitigation

At Opus Research we bring all of these factors together. For example, when it comes to road traffic noise, we have researched how different road surface types affect the level of noise generated, how communities respond to noise and how the noise generated by a road influences the value of adjacent properties.

This knowledge is then used to inform national standards or is incorporated in policy or guidance documents such as those produced by New Zealand Transport Agency.

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