Effects of Inadequate Geotechnical Investigation on Civil Engineering Projects

Magdi Zumrawi

Abstract: This paper aims to focus on the problems of inadequate geotechnical investigations which lead to unsafe designed foundations; construction delays and extra costs for civil engineering projects. Inadequate geotechnical investigations can arise from lack of client awareness; inadequate finance; insufficient time and lack of geotechnical expertise. The reliability of the information contained in the geotechnical report has strong influence on design; construction; project cost and safety. Thus; it is quite important to have a clear; concise and accurate geotechnical report by qualified geotechnical engineers in order to ensure the reliability of the investigation results. A case is presented to illustrate the problems of inappropriate geotechnical investigation; insufficient knowledge of site condition; and importance of geotechnical supervision.
