How we approach the work
Vibration must be assessed according to its generation mechanism, propagation path, building response and study purpose. The same record may have different implications for comfort, equipment diagnosis, construction monitoring or structural assessment.
01
Applications
- Vibration from rail, metro or road traffic.
- Construction, excavation, demolition and construction plant.
- Machinery, generators, fans, pumps and industrial processes.
- Complaints, comfort or perception in buildings.
- Propagation tests and transfer functions between locations.
02
Measurement planning
- Selection of parameter, frequency range and acquisition rate.
- Sensor location and mounting appropriate to the purpose.
- Logging of events and operating conditions.
- Synchronisation between locations or with noise channels.
- Definition of alert levels for monitoring where applicable.
03
Interpretation
- Time, frequency and event-based analysis.
- Comparison between locations, conditions and periods.
- Separation of background vibration from relevant events.
- Assessment against criteria appropriate to the objective.
- Statement of limitations and need for further measurement.
