Why continuous monitoring?

Reduce risk on your construction project

  • Continuous vibration monitoring to manage the risk of building damage or disruption to nearby sensitive equipment
  • Continuous noise, dust and vibration monitoring to manage nuisance and limit complaints

Noise Sentinel alerts you immediately when noise or vibration exceeds defined levels, allowing you to take immediate action to change operations before a breach occurs. Investigation will help you determine the cause and ascertain if it was your responsibility.

Manage noise proactively to avoid costly delays

Noise is not always continuously monitored at construction sites, but construction in built-up areas can cause a significant noise nuisance - particularly where works continue into the night, and at weekends. If significant complaints are received, regulators are duty-bound to investigate, and may impose costly operating practices and restrictions - introducing significant delays and cost to the project.

  • Determine noise sources: Assessment +Read More Determine noise sources: Assessment
    Assessing noise is essential to ensure that noise limits are respected. Noise limits in urban environments are defined per source type – i.e., they are specific for traffic, construction sites, industrial plants, entertainment and leisure activities, and for neighbours.

  • Predict and prevent noise: Planning +Read More Predict and prevent noise: Planning
    Noise planning prevents noise issues arising and optimises the use of resources by managing the future noise environment. Noise mapping is done through calculations, and is essential for planning urban development of residential areas, such as with industrial sites, highways and airports.
