4.2 Geotechnical site survey reports 
4.2.1 Content of the geotechnical site survey reports 
The geotechnical site survey reports, i.e. the preliminary or main geotechnical site survey re 
port, must contain at least the following as an independent part of the geotechnical report in 
accordance with DIN 4020 in the respective project phase except a precise specification of 
the objective of the investigation as well as documentation of the supporting documents 
made available regarding the structure: 
• general specifications regarding the construction task, 
• specifications regarding geological conditions, 
• specifications and boundary conditions regarding field and laboratory tests, 
• findings from boreholes and probes, 
• specifications for determining site-based water depth, tide and correction of water depth 
depending on time, including specification of the reference level (e.g. chart datum (LAT), 
MSL), 
• specifications regarding geodetic measurements of geotechnical surveys including refer 
ence (e.g. World Geodetic System 1984, UTM), 
• specifications for calculating, correlating and interpreting (classification) of the in-situ test 
results, 
• bottom profile with soil types and the altitude of boundaries between strata relative to the 
seabed and sea level incl. specification of the reference system (e.g. chart datum (LAT), 
MSL), 
• the results of laboratory tests and modelling which were carried out if necessary, 
• a clear summary of the test findings, 
• a summary of characteristic soil mechanical parameters of main soil types as well as the 
associated range of the parameters, 
• a comprehensive description of the soil and 
• a geotechnical site assessment.
