Expert Testimony

Put GeoSonics/Vibra-Tech’s experience and expertise in your corner. Whether for public meetings, hearings or litigation, our clients have trusted and relied on our expert testimony since the early 1940s.

No matter how carefully work is conducted, complaints can occur. And, these complaints can lead to litigation. From the very beginning of a project, GeoSonics/Vibra-Tech can provide experienced consultants who understand all sides of the issues. We also understand that all parties involved have their own questions and concerns. We are able to address those questions and concerns in clear and uncomplicated language, and in a way that is fair to all parties.

GeoSonics/Vibra-Tech has qualified experts with substantial experience as impartial, third-party participants in public meetings. Furthermore, our experts can address or provide testimony in front of political bodies, regulatory agencies, citizen groups and other public forums.

As a result of our extensive experience observing and studying the effects of ground vibration and sound pressure on structures during blasting, pile driving and other vibration-producing operations, we have developed a unique set of skills. Those skills are put to use when we are asked to provide opinions on uncommon occurrences like pipeline explosions, unplanned detonations and other geologic or weather-related phenomena. During our long history, we have conducted over a million inspections/investigations on structures of nearly all types. From huts in a desert to skyscrapers in New York City, and from landforms to landmarks, we have observed and documented conditions before, during and after projects that produced perceivable effects at those structures.

GeoSonics/Vibra-Tech has a reputation of providing solid technical support. We also have a strong reputation of possessing the knowledge needed to successfully defend against meritless claims of damage. We fully understand, however, that our clients expect precise explanations when claims of damage do have merit. And, we have helped our clients avoid wasting time and money on needless litigation in situations when damage was a result of their operations. Whether we are consulting on behalf of a blaster who knows there are vibration or noise effects as a result of his or her operation, or a homeowner who perceives those effects, we can be trusted to understand the science involved and provide consistent and competent explanations in an understandable and fair manner.
