Structural engineers charged with designing a structure depend upon the input of geotechnical engineers to determine the appropriate foundation type for a site and building design. Practicing Structural Engineers are faced with educating their clients about services needed from the Geotechnical Engineer, how to retain the right Geotechnical Engineering firm for the project, and how best to implement the recommendations of the Geotechnical Report on their project. This Guide was created to discuss the structural engineering business practice aspects of working with a Geotechnical Engineer.
