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  construction ­
  phase  within  the  context  of  Standard  Design  (see  also  Table  2).

(Konstruktionsphase)”

The  soil  and  foundation  expertise  report  in  the  development  phase  („Baugrund-  und  Griindungsgutachten
  (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  (Entwicklungsphase)”) ­
  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  report. ­
  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  geotechnical ­
  site  survey  report  and  the  soil  and  foundation  expertise.
