Noise monitoring

Construction often takes place close to occupied structures or areas of designated sensitivity. Piling activities have allowed PMC to introduce the Cirrus Sound Monitor as a practical and inexpensive means of monitoring the sound levels induced during piling and other site related activities.

The potential for nuisance due to noise caused by construction activity is a cause for concern to both the public and local authorities.

PMC are able to provide single monitoring systems capable of assessing the sound levels across a designated area.

Vibration monitoring

PMC deploys the Vibrock V801 seismograph as a practical and inexpensive means of monitoring the vibrations induced during piling and other site related activities.

The potential for nuisance due to vibration caused by construction activity is a cause for concern to both the public and local authorities.

PMC provides single or multiple monitoring systems capable of assessing the groundbourne vibrations across a designated area.
