Vibration monitoring
Construction vibrations are measured with triaxial geo-phones installed in-ground at a structure of interest and compared to industry established criteria. Ground vibration measurements are collected during the early stages of a project to develop attenuations useful for optimizing production, predicting and minimizing vibrations impacts, and preventing work stoppage. AMS offers vibration monitoring services for a variety of projects. We provide remote monitoring (telemetry) systems, close-in, real-time and other specialty ground vibration monitoring solutions to meet specific project needs
Vibration Monitoring for Blasting
AMS provides blasting and seismograph record analysis and reporting to evaluate vibration records in response to changes in blast design and practice. We have extensive field experience working with mines, quarries, and construction personnel to reduce both on- and off-site impacts of vibrations from rock blasting and construction equipment producing vibrations and noise.
Vibration Monitoring for Heavy Equipment
Best practices in the construction industry indicate construction companies should monitor vibrations and noise from equipment used for rock excavation (trenchers, hammers), pile driving, and vibratory compaction of soils, base course, and asphalt. When construction equipment operates near inhabited buildings, vibrations can be particularly disturbing to persons inside due to the repetitive and continuous nature of the equipment mechanical energy. The ground motion energy often contains frequency components that “match” the natural frequency of structures. Resulting motions in structure walls tend to cause loose objects resting against or on walls to rattle, producing noise. This noise often startles and alarms residents, leading them to think the structure is being damaged when indeed the displacements are far too low to cause structure cracking.
Structure Condition Surveys
Pre-blast/pre-construction surveys document existing conditions of nearby structures with high definition photos and/or video before the project begins.
- Trained and experienced technicians document existing conditions
- Inspection surveys include all exterior and interior surfaces, with property owner permission
- All inspections refused by property owner are well documented
