Geotechnical engineering is important in civil engineering, but also has applications in,, and other that are concerned with construction occurring on the surface or within the ground. Geotechnical engineering uses principles of and to investigate subsurface conditions and materials; determine the relevant physical/mechanical and chemical properties of these materials; evaluate and man-made soil deposits; assess risks posed by site conditions; design and structure; and monitor site conditions, earthwork and foundation construction. A typical geotechnical engineering project begins with a review of project needs to define the required material properties. Then follows a site investigation of, rock, fault distribution and properties on and below an area of interest to determine their engineering properties including how they will interact with, on or in a proposed. Site investigations are needed to gain an understanding of the area in or on which the engineering will take place.

Investigations can include the assessment of the risk to humans, property and the environment from natural hazards such as,,,, and. A geotechnical engineer then determines and designs the type of foundations, earthworks, and/or pavement subgrades required for the intended man-made structures to be built. Foundations are designed and constructed for structures of various sizes such as high-rise buildings,, medium to large commercial buildings, and smaller structures where the soil conditions do not allow code-based design. Foundations built for above-ground structures include shallow and deep foundations. Retaining structures include earth-filled and retaining walls. Earthworks include,,,,, deposition of and sanitary landfills.
