Some construction activities generate ground vibration. Pile driving, rock breaking and dynamic compaction can be a source of annoyance and concern to occupants and owners of neighbouring buildings. While there is currently no regulation for limiting ground vibration from construction sites, companies may need to demonstrate that ground vibration from their work sites are not causing damage to neighbouring structures.
Vibration can be measured and therefore controlled. Ground vibration monitoring is a useful tool for understanding the effect construction vibration has on neighbouring buildings, their occupants and infrastructure. Monitoring can also help prevent damage to neighbouring structures and reduce the potential for damage claims. Vibration monitoring is a good proactive measure for projects with close neighbours and may also be implemented to address concerns or complaints from occupants of nearby buildings. Increasingly, many projects now have ground vibration monitoring as a mandatory part of the job scope.
Terrock offers Australia-wide ground vibration monitoring, compliance reporting, monitor hire and training services. Terrock personnel can also communicate with people neighbouring work sites to help give them a better understanding of the nature of the ground vibration and the current vibration levels, which can help alleviate unnecessary concern. In some situations a brief period of monitoring may be required to confirm the peak ground vibration levels generated from onsite activities. In other situations long-term or continuous monitoring may be required.
All of Terrock's vibration monitoring equipment complies with AS2187 specifications. Annual calibration certificates for vibration monitors are available if required.
