The Free State of Thuringia has plans to improve flood protection
ordered. The existing dikes are to be relocated as far as possible in order to
to be able to make use of the flood plains at an early stage. There will be a
differentiated flood protection with partial protection systems for agriculture (protection against
frequently recurring floods) and full protection systems for local areas and infrastructure
(protection against rare recurring flood events).
Geotechnical construction support
Within the scope of geotechnical construction supervision, the following services are to be provided:
. Checking and assessing the conformity of the upcoming subsoil and
groundwater conditions with the corresponding geotechnical reports,
Monitoring and acceptance of the subsoil and the dike support, the foundation floor
of sewer structures as well as excavation pit embankments, documentation of the services in text

Subsoil improvement
. monitoring the implementation of any necessary measures for soil and
Substrate improvement, documentation of performance in text and image
