Geophysics is a specialized branch of geology that utilizes physical principles to study properties of the earth. Dawood utilizes an indirect investigation method which can be completed with little to no disturbance to the property we are investigating. This is in contrast to the more traditional, direct investigation methods such as test pits and core borings, which can cause significant disturbance and disruption of the property, as well as being a more expensive option.

Our Geophysics Group works hand-in-hand with our Geotechnical Group to provide integrated solutions to a wide-range of subsurface challenges and delivers quality products and services tailored to your specific project needs. Dawood has developed a diversified client list that includes private-sector clients such as homeowners, contractors, developers, and several Engineering News Record (ENR) top-ranked engineering firms, as well as public-sector clients, including several Pennsylvania Department of Transportation (PennDOT) Districts.
