The Land Brandenburg, represented by the Ministry for Land, Agriculture, Environment, and Consumer Protection (MLEUV), represented by the State Environmental Office (LfU) in Germany from Europe region has released this tender for The original scope of the construction works includes for the northern area a replacement reconstruction of the riverbank wall over a total length of approximately 370 m from Römertreppe to Ziegelstraße, and for the southern section of approximately 200 m in length north of the city bridge to Römertreppe, a concrete rehabilitation of the riverbank wall. Within the scope of the construction contract, a approximately 370 m long sheet pile wall made of 17.5 m long sheet piles has been installed, which ensures flood protection at a level of +24.20 m NHN and enables the creation of the fore-sill. The additional agreement (NV) No. 15 includes the following 3 additional offers (NTA): NTA 35 (Implementation of jointing plan for in-situ concrete wall), NTA 36 (Implementation of jointing plan for prefabricated elements (production) and NTA 37 (modified execution of dam wall closure). NTA 35 Implementation of jointing plan for in-situ concrete wall These services are required to ensure the proper sealing of the now planned in-situ concrete wall ZTV-W and to guarantee the functionality of the flood protection system. The in-situ concrete wall is a modified service that results from the rehabilitation concept of the construction company due to defects in the piles. The in-situ concrete wall itself is not part of this additional agreement, but only the works necessary to seal the working joints. NTA 36 Implementation of jointing plan (production) These services are required because the volume of prefabricated elements has been changed and additional requirements have arisen from the implementation of the sealing concept. Prefabricated elements must be significantly reduced. This results in a greater number of elements (125%). Additionally, the implementation of the sealing concept according to ZTV-W requires horizontal and vertical cutouts to later install the sealing materials. NTA 37 Modified execution of dam wall closure The additional agreement includes extra costs for a changed division of the dam wall closures. The originally tendered 2-part execution of the dam wall closures with a central post shall be changed to a 3-part execution with 2 central posts. This required an additional structural verification and adjustment of the construction plans. with tender notice no. 692860-2026 published on 08 Oct 2026. The tender is due to expire on 06 Jan 2027.
