Many public- and privately-funded endeavors require subsurface information.  Geophysical measurements provide a basis for projecting cultural and geological observations into the underground.  Imaging the subsurface using geophysical/engineering/geological technology is often less expensive, safer, and faster than wholesale, brute force drilling and excavating  Geophysical methods are nondestructive, and relatively unobtrusive.  Subsurface Surveys specializes, with many years of experience, in geophysical data acquisition, processing and interpretation in terms of real world geology.
