Geotechnical engineering is the application of the sciences of soil and rock mechanics, engineering geology and other related disciplines to civil engineering design and construction, and to the preservation and enhancement of the environment. Geotechnical engineering plays a key role in all civil engineering projects, since all construction is built on or in the ground.
