Vibration Monitoring
Did you know that Sayre Associates offers vibration monitoring services? We are the only firm based in South Dakota that offers this valuable service for construction or blasting activities. It provides a method to measure the actual vibration in the ground being produced by construction or blasting activity. Keep reading to learn more and contact us if you have any questions!
Why vibration monitoring services?
To collect data on existing structures, utilities, etc. regarding the level of vibration being produced on site of the construction project.
What methods are used to monitor vibration?
Pre-Existing Condition Survey
By use of video camera and pictures, the existing condition of nearby structures and pavements are recorded prior to construction activity. This provides a good baseline condition of the existing structures nearby.
​
Vibration Monitoring
We use seismographs that are strategically placed to measure and record the actual ground-induced vibrations to obtain accurate vibration levels at the structure being monitored.
​
Crack and Movement Monitoring
Crack gauges, crack meters and small scale movement instruments can be installed on existing structures of concern and monitored before, during and after construction. This provides record of movement and provides a time frame as to when the movement occurred.
​
Remote Monitoring Capabilities
Both vibration and crack monitoring can be done remotely and data sent out immediately after recording an event. This provides exact times of the triggering event and helps determine what was the trigger event.

What should people know about vibration monitoring?
Vibration monitoring serves to not only protect property owners but also the contractor and project owner. By monitoring, we are able to record the vibrations to determine if they are excessive to the point of possibly causing damage to properties and bring it to the attention of the contractor so changes to their process can be made. It can also serve to protect the contractor against false accusations, particularly when done in conjunction with a pre-blast survey which documents items such as existing cracks in foundations and walls.
​
Vibration monitoring is done to collect actual vibration levels during construction and blasting projects. Even if the vibration levels are within limits, collecting this data provides substantial proof of compliance in case an accusation is made on another parties' part. If the levels are high, causes can be investigated in case changes of method need to be made to reduce vibration levels.
