The bottom panel is a common, albeit inappropriate name for the " Geotechnical report " an expert in geotechnical engineering, the results of the investigation and testing of soil and groundwater conditions of a planning area and its assessment with regard to the solution of a structural task according to the prior art contains, including information on the nature of the soil to be found there. Since 2008, a geotechnical report is required as a basis for planning and implementing a construction project building regulations in Germany ( Euro Code 7, see below). For the design of buildings and civil engineering structures require planners and structural engineer ( structural engineers ) the precise statements about the viability of the soil in order to dimension the foundation elements (foundations, piles) and to plan the implementation of civil works ( excavation, groundwater drainage, waterproofing, impact on the environment, etc.. ). The more accurate term is therefore " ground and foundation report".
Geotechnical reports are based on the EN 1997-2 - Euro Code 7: Design, analysis and design in geotechnical engineering - Part 2: Ground investigation and testing of the subsoil and in addition in Germany according to DIN 4020 - Supplementary rules to DIN EN 1997-2 created. You are ultimately part of the geotechnical design report according to EN 1997-1 in conjunction with DIN 1054 Verification of the safety of earthworks and foundations. Therefore, such an opinion for the planner contains all essential statements on the creation of opportunities as well as on the load capacity of the subsoil (permissible soil pressures or recoverable pile resistors), the characteristic values of the soil parameters and the expected basis of water level.
A ground survey can also refer to the investigation and assessment of any existing soil contamination and contaminated sites.
