The objective or objectives of Geophysical imaging may be very specific or very general.  Like any other tool, geophysical imaging has advantages and limitations, and irrespective of the objective, the supervising engineer or the project manager should ensure that any geophysical methods employed provide useful and cost-effective information. To ensure appropriate methods are used, the supervising engineer should insist the utility

Geophysics is a valuable tool, but like any other tool it has advantages and limitations. The main advantages of Geophysics are non-invasiveness, high productivity, 2D/3D coverage and applicability in challenging environments, as discussed in the previous post. However, the limitations of any non-intrusive technology are that the properties and conditions of the imaged targets cannot

$40,000 to replace a pre-tensioned concrete slab in a multistory building because a contactor cored through a tendon. Tens of thousands of dollars in loss and 3 days of downtime with multiple contractors onsite because a contractor damaged a building electrical service cable during concrete saw cutting. Lengthy delays and soaring costs due to removal

Simply put, Geophysics is a tool that helps us to see what’s in the ground without digging it. A more formal definition (by EEGS*): Geophysics is the non-invasive investigation of subsurface conditions through measuring, analyzing, and interpreting physical fields at the surface. There are two main branches of Geophysics that often overlap in terms of
