3.3.2.5.5 Additional geotechnical information and verifications
All presumptions made with respect to the devised foundation elements and the precondi
tions for realising the construction project shall be accordingly specified.
All geotechnical verifications which will have to be presented for the devised foundation ele
ments during the installation and operating phases (please refer to chapters B3.4.4 and B3.5.4)
shall be accordingly specified.
3.3.3 Geotechnical documents to be submitted
3.3.3.1 Geotechnical design report
The design, calculations and dimensioning of the foundation elements shall be accordingly
represented in the geotechnical design report in a verifiable manner. The formal and content
requirements set down in DIN EN 1997 (EC 7) placed on the foundations of offshore structures
are detailed more precisely in the following:
The Geotechnical Report of the expert for geotechnics compiled in accordance with the BSH
Standard Ground Investigations represents the basis on which the Geotechnical Design Re
port is based but is not an integral part of this report. The Geotechnical Design Report con
tains all relevant information and representations with respect to the design of the foundation
elements, in particular
• The presentation of the assumptions made based on the scope for making selections and
decisions provided by the applicable standards, and the justification thereof. These include,
in particular
- The selection of subsoil parameters used
- Where necessary, reasons for deviations in the applied subsoil parameters from those
detailed in the geotechnical report
- The determination of the load combinations relevant to the calculations
- The classification of the load combinations in different calculation situations
- The assignment of safety factors to loads and resistances and
- The representation of the implementation and assessment of component tests, e. g. pile
load tests, incl. specific representation of the verification methods used
• The representation of the engineering models used for the verifications, including the model
assumptions and simplifications used
• The representation of the calculation processes used for the verifications, including their
implicit prerequisites
• The values of the subsoil parameters used for the verifications
• The derivation of the values for model parameters additionally required
• The results of the load-bearing capacity verifications
• The results of the serviceability verifications
• The representation of the appropriateness and the adequacy of the examined ultimate limit
state
• The representation of the appropriateness and the adequacy of the examined serviceability
limit state
• Recommendations for measurements conducted on the structure and on the subsoil (mo
nitoring), as well as
