Part B - Verifications and approval requirements 
• Where necessary, the justified representation of the necessity, the appropriateness and the 
adequacy of the observation method and 
• Information detailing all the certificates and verifications of the preconditions to be presen 
ted during the installation and operating phases. 
Whilst construction is under way, the construction-specific supplementary geotechnical re 
ports, together with their verification components, will be added to the geotechnical design 
report as construction progresses. These include the evaluation and assessment of compo 
nent tests, such as dynamic pile load tests, the documentation and assessment of installation 
logs (pile-driving logs, injection logs etc.), as well as the evaluation and assessment of the ef 
fects of deviations of the installation results from the assumptions, preconditions and provi 
sions set down in the geotechnical design report. 
3.3.3.2 Geotechnical as-built documentation (geotechnical installation report) 
Once the installation of the foundation elements has been completed, a verified geotechnical 
installation report shall be presented. This geotechnical installation report constitutes the 
“Geotechnical component of the as-built documentation”. 
Based on the geotechnical design report, this installation report shall contain all the relevant 
information concerning the implemented installation with respect to the stability and the serv 
iceability of the foundation elements, in particular compliance with and deviations from the 
assumptions, preconditions and provisions applying to the verifications regarding the geo 
technical design in accordance with chapter B3.3.3.1. 
3.3.3.3 Supplementary reports to the geotechnical design report 
In as far as the data and findings required for the safety verifications only become available 
during the actual installation of the foundation elements, appropriate supplementary reports 
to the geotechnical design report shall be developed by the planning expert for geotechnics. 
These shall include respective references to the geotechnical design report in accordance 
with B3.3.3.1. 
In as far as the installed foundation elements deviate from the assumptions, preconditions 
and provisions applying to the verifications of the geotechnical design report, supplementary 
reports to the geotechnical design report shall be developed to certify that the stability and 
serviceability of the foundation elements is maintained under the deviating conditions. 
3.3.3.4 Documents to be submitted for the 2 nd release 
The following verified geotechnical documents shall be included with the application docu 
mentation for the 2 nd release. All documents shall comply with the BSH Standard Ground In 
vestigations: 
Main ground investigation report 
Subsoil and foundations survey (design phase) as well as the 
Geotechnical design report and 
Where necessary, supplementary expert opinion on cyclic loads (“cyclics”) 
[Doc. No. 320] 
[Doc. No. 321] 
[Doc. No. 322] 
[Doc. No. 323] 
[Doc. No. 324] Report from the company conducting the dynamic pile load tests, including 
details on the planned sensors, their respective installation and planned cable 
routes
