Site investigations are undertaken by experienced geotechnical engineers, engineering geologists, and field technicians to provide information on a site’s surface and subsurface conditions, the results of which will determine the design of earthworks and foundations for structures.
Dependent upon the site and its intended end use, an investigation can vary from a visual walkover appraisal, which may include observations of general topographical features and geomorphological mapping, to a detailed subsurface investigation.  Subsurface investigations are undertaken in order to obtain information on soil conditions and to facilitate site assessment and analyses.
Investigation methods include boreholes, test pits, and trenching, accompanied by in-situ and laboratory analysis of soil samples to collect data on a variety of soil characteristics including shear strength, groundwater level, moisture content, compressibility, and potential.
