3  Foundation  elements
3.1  Preliminary  remarks
The  basic  definitions  pertaining  to  the  geotechnical  systems  resulting  from  the  subsoil  and  the
foundation  elements  are  derived  from  DIN  EN  1997  (EC  7)  and  the  references  contained
herein.
The  following  geotechnical  documents  are  required  for  submitting  an  application  to  the  BSH:
(1)  In  accordance  with  the  Standard  Ground  Investigations:
-  Preliminary  ground  investigation  report
-  Main  subsoil  inspection  report
-  Subsoil  and  foundations  survey  (development  phase)  and
-  Subsoil  and  foundations  survey  (design  phase)
(2)  In  accordance  with  this  Standard  Design:
-  Geotechnical  design  report,  where  necessary,  including  a  supplementary  expert  opinion
on  cyclic  loads  (“cyclics”)
-  Geotechnical  as-built  documentation  (geotechnical  installation  report)  and
-  Supplementary  geotechnical  reports.
The  subsoil  and  foundations  survey  (design  phase)  contains  proposals  which  allow  for  cyclic
loads  when  calculating  the  foundation  elements  (“cyclical  concept”).  The  geotechnical  design
report  may  also  incorporate  a  supplementary  expert  opinion  which  includes  the  results  of
laboratory  tests  aligned  to  the  specific  design  in  question  to  investigate  the  ground  properties
under  cycle  load  application  (supplementary  expert  opinion  on  the  “cyclics”).
The  documents  listed  in  (1)  above  constitute  the  basic  planning  documents.  These  shall  be
compiled  by  a  geotechnical  expert  in  accordance  with  the  BSH  Standard  Ground  Investigations. ­
  The  documents  listed  in  (2)  above  constitute  the  geotechnical  planning  contribution  to
the  design  of  the  foundation  elements.  These  shall  be  developed  by  a  planning  expert  for
geotechnics  on  behalf  of  the  architect.  The  geotechnical  design  report  shall  include  the  basic
planning  documentation  by  way  of  reference  to  the  ground  investigation  report  and  the  subsoil ­
  and  foundations  survey  (design  phase).
Table  3-1  illustrates  the  most  important  content  and  the  authors  responsible  for  this  content,
as  well  as  the  descriptions  of  the  reports  in  both  of  the  BSH  standards  quoted  above  and  the
corresponding  reports  in  the  respective  normative  standards  with  a  view  to  providing  precise
information  for  the  BSH  application  procedure.
