Geotechnical engineers research and study soil to evaluate its suitability for foundations. They investigate and assess construction sites, conduct lab tests, create designs for structures, supervise construction, and write and present reports. They work on such projects as designing tunnels, roadways, retaining walls, and earth dams, as well as helping to create strategies for the clean-up and management of contaminated sites.
Geotechnical engineering uses principles of soil mechanics and rock mechanics to investigate subsurface conditions and materials; determine the relevant physical/mechanical and chemical properties of these materials; evaluate stability of natural slopes and man-made soil deposits; assess risks posed by site conditions;
Geotechnical engineering and engineering geology are a branch of civil engineering. The specialism involves using scientific methods and principles of engineering to collect and interpret the physical properties of the ground for use in building and construction.
