Investigation of Geotechnical Failures and Documentation

The Geotechnical investigation is the backbone of any civil construction activity. The index and engineering properties of soil layers are to be estimated in a realistic manner for the design of structures. In general, the properties of soil vary randomly both in vertical and horizontal directions. The concept of probable soil description, effectiveness of exploration, factors to be considered in the report documentation of Geotechnical investigations are highlighted in this paper. The concept of Forensic Geotechnical Engineering (FGE) is also introduced. It is concluded that Geotechnical investigation is an Engineering ART and is to be done only by the qualified Geotechnical Engineer. Biased and unbiased properties along the borehole are to be reported for the proposed project site. Geotechnical report is to be prepared without using any JARGONS and can be followed by a non-technical person in the event of legal complications.
