For the design foundation, it is important to know not only the structure and load of the building, but also soils properties in the subsoil. Ignoring soil properties may result in an incorrect design of foundation, which may later cause a failure in building structure, because generally known foundations function is to transfer load effects into the ground. In smaller buildings, an engineeringgeological survey is not usually carried out, but basic data on the territory is obtained from archive reports.
