Table 1: Steps involved in geological and geotechnical surveys and investigations as well as 
all reporting. Stages 1 to 4 are the development phase, stage 5 is assigned as the construc 
tion phase within the context of Standard Design (see also Table 2).

(Konstruktionsphase)” 
The soil and foundation expertise report in the development phase („Baugrund- und Griin- 
dungsgutachten (Entwicklungsphase)”) contains mainly an assessment of the foundation 
which is based on current investigation findings which refer to the method applied and the 
variants that were designed. 
The preliminary geotechnical site survey report (“Baugrundvoruntersuchungsbericht”), soil 
and foundation expertise (development phase) („Baugrund- und Grundungsgutachten (Ent 
wicklungsphase)”) and geological report (“Geologischer Bericht”) are the rudiments for the 
design basis and the preliminary design. These must be presented to the Federal Maritime 
and Hydrographic Agency in accordance with the specifications in the Standard Design in a 
verified format for the first release. 
The findings of the geological report are to be integrated into the geotechnical site survey re 
port. Together with the soil and foundation expertise (construction phase) („Baugrund- und 
Grundungsgutachten (Konstruktionsphase)”) it is part of the rudiments of the basic design. 
These supporting documents must be presented to the Federal Maritime and Hydrographic 
Agency in accordance with the specifications in the Standard Design in a verified format for 
the second release. 
Part C, Section 2.3.3 contains differing regulations for offshore stations. 
See part B, section 7 for the contents of the geological report, see part C section 4 for the contents of the geo 
technical site survey report and the soil and foundation expertise.
