Geophysical Survey


Geophysical survey techniques utilize noninvasive sensing equipment to reveal a 3D model of what is under the surface of the ground. From an organized onsite survey through computer-based data processing, geophysical data can be analyzed for a variety of attributes. This systematic form of spatial data collection and analysis is useful in a wide variety of industries including archaeology, forensics, engineering, utility locating, geology, and environmental sciences. Through a better understanding of this widely-used technology, industry leaders can lessen long-term costs and limit the damage to historical, cultural, and environmental resources.

Bigman Geophysical provided excellent service, and was extremely responsive to our rapidly changing project needs; their staff repeatedly mobilized quickly and on very short notice to help us evaluate multiple project alternatives. We were very pleased with results and will definitely use them again in the future.

Bigman Geophysical offered a unique solution for my project.  I was investigating buried debris on a residential housing development where mass borings would have been prohibitively expensive.  Due to Dr. Bigman’s unique expertise in archaeology, he was able to delineate the underground debris limits while saving project time and cost. Throughout my 15 years in the design/construction industry, I have yet to find anyone to provide me with this level of service.
