In order to manage your vibration, you need to know what you are trying to protect. Once you know what you need to protect, you can set vibration limits. Monitoring is done for a number of different reasons, including
Permitting
Project specifications
Regulatory compliance
Community relations
Litigation
In any of these situations, you will need vibration data to verify you are staying within set limits specific for your project. Monitoring data allows you the confidence to know you are operating at levels that are safe for the structures you are concerned about, thus giving you peace of mind and the ability to mitigate your vibration risk.
