Geotechnical Investigations are carried out to acquire the information on the physical properties of soil for proposed structures and for the repair of distress to earthworks and structures caused by subsurface conditions. Also, geotechnical investigations survey are also used to measure the thermal resistivity of soils or backfill materials required for underground transmission lines, oil and gas pipelines, radioactive waste disposal, and solar thermal storage facilities. A geotechnical investigation will include surface exploration and subsurface exploration of a site. Subsurface exploration usually involves soil investigation survey sampling and laboratory tests of the soil samples retrieved.
Geotechnical Investigation is very important before any structure is built– whether it is your own dream house, an industrial shade, a multiplex, a shopping mall, a warehouse, a multi-storied building, or even small and big infra projects like bullet trains. metros and so on.
Surface exploration can include geologic mapping, geophysical methods, and photogrammetry or it can be as simple as a geotechnical professional walking around on the site to observe the physical conditions at the site.
An important basis for the planning and construction of building and infrastructure projects (comprising various types of structures as a foundation, excavation pit, land reclamation, beach nourishment, etc.) is the knowledge of the ground conditions. For this purpose, the geotechnical investigation with its respective services shall be carried out. Their nature and extent depend on the type of the structure, the difficulty of the structure, and the expected ground conditions.
There are few important steps to be followed as part of exercises for Geotechnical Investigations;
