Germany – Architectural, construction, engineering and inspection services – HÖP Ubstadt Weiher - Planungslos 1

The State of Baden-Württemberg, represented by the Karlsruhe Regional Council, Department 53.1, is implementing the flood protection and ecology project in Ubstadt-Weiher, abbreviated as "HÖP Ubstadt-Weiher", along the Kraichbach, for which the plan approval decision has been made. The Kraichbach is a first-order watercourse in the affected area. In addition to the flood protection measures, extensive water ecological improvements are planned to achieve the objectives of the EU Water Framework Directive (WRRL). The project "HÖP Ubstadt-Weiher" also promotes the wetland character of the nature reserve "Bruch bei Stettfeld". The project "HÖP Ubstadt-Weiher" thus improves flood protection in the settlements of Ubstadt-Weiher and makes a significant contribution to the ecological enhancement of the Stettfelder Bruch. The engineering measures essentially comprise the new construction or upgrading of flood protection dykes, the new construction of a flood protection wall, the water ecological development of the Kraichbach in a so-called development corridor, the new construction of culvert structures and the dismantling and new construction of a bridge. The project area is largely located in the nature reserve "Bruch bei Stettfeld". This is an extremely sensitive natural area with an above-average species richness, including the occurrence of particularly and strictly protected species. This results in very high requirements for species and nature conservation for the construction measures. This is to be ensured, inter alia, by means of complex planning of the construction process and numerous regulations, e.g. construction time regulations, protective measures for trees in the construction area, procedures for the dismantling of dykes and river banks, reuse of soils, etc. In addition to the local construction supervision, ecological construction supervision and soil science construction supervision are used for the monitoring of the protective measures. Suitable measures for flood protection must also be determined and permanently maintained for the duration of the construction process. Further special features of the project are suspected ordnance areas, which were identified on the basis of an aerial image evaluation, as well as archaeological monuments or cases to be investigated, which are located in the project area and which must be recorded after the find. Furthermore, there are construction measures affecting the adjacent route of Deutsche Bahn AG. In addition, the route of the product pipeline Huttenheim-Heilbronn of the Bundeswehr, so-called NATO pipeline, crosses the construction site. In addition to planning lot PL1, further planning services are to be awarded, including planning lot PL2 - environmental planning, soil science construction supervision, geotechnics, etc.
