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. Geologists define recommended dispersion of values for single geology properties, which is reflected in bearing capacity of foundation soil and the dimensions of foundation foot. Base soil monitoring due to varying soil shear strength parameters under consistency changing and observation of changing bearing capacity of soil confirmed the importance of conducting and evaluating engineering geological surveys for optimal design of the foundation structure.
