Vibration Monitoring: Reducing Liability

Geotechnology engineers working at project site in downtown St. Louis

VMGeoBlast2For years, Geotechnology has been helping protect structures and reduce its clients’ liability related to vibrations from construction, demolition, or other industrial activities by performing precondition surveys and vibration monitoring services. Historically, vibration monitors have required ample space for setup, a well-founded protective system from the always chaotic construction or industrial environment, and plenty of “baby-sitting” hours for instrument setup, maintenance and data downloading. For these reasons, we are excited to have recently enhanced our vibration monitoring capabilities with the use of a wireless and internet- based vibration monitoring network.

INFRA Net2The vibration monitors provide automated, wireless transmission of data to Geotechnology via the INFRA Net website which saves time and enhances productivity throughout the duration of each project. The vibration monitors are compact, waterproof, and portable, each containing a geophone, datalogger, and communications capabilities. The small size of the vibration monitors makes them easy to mount on structures or couple to the ground in relatively out-of-the-way places with no wires to get in the way. The web-based software allows us to remotely set up, program and track the status of vibration monitors. The monitors send out immediate automatic notifications via text or email to assigned contacts at Geotechnology, Inc. in addition to the owner, project manager, etc., if a pre-assigned vibration threshold is exceeded. Also, recorded maximums can be plotted and analyzed over a pre-set time interval. Waveforms can be analyzed and reported immediately upon collection and without being on site. The internet-based system has allowed Geotechnology to provide more responsive vibration monitoring results with less effort and cost.
