Underground Rail Vibrations
The client believed that the vibrations from the passing underground line had been increasing and was concerned about the potential for damage to the property.
In order to capture the vibration from the underground rail line two separate vibration monitors were used on different floors in the property. The monitors were used to identify the magnitude and frequency of vibration levels from the underground rail line. Having two separate monitoring locations allowed Xi to identify and remove local vibrations from the analysis, such as footfalls to isolate the underground rail vibrations. All of the data was uploaded to the cloud in real time where it could be accessed by both the client and Xi Engineering.
A final report was given to the client outlining the findings from the measurement, including acceleration, velocity and Vibration Dose Values (VDV).
