The purpose of this website is to provide engineers with a basic knowledge of geophysics and nondestructive test
(NDT) methods for solving specific engineering problems during geotechnical site investigation, construction, and
maintenance. The website is not intended to make engineers experts in the field of geophysics, but rather to
provide them with tools that will assist them in the use of suitable geophysical and NDT techniques to evaluate
problems for design, planning, construction, or remediation efforts.
