On behalf of the Federal Republic of Germany, represented by the Lower Saxony State Authority for Road Construction and Transport, Nienburg division, the construction overhead management for the replacement of the Weser bridge Stolzenau B 215 is to be provided.
Bundesstraße 215 runs from Glissen to Stolzenau and on via Landesbergen, Nienburg and Verden to Rotenburg. As a north-south connection in the Verden - Minden area (via the B 482 and B 61) or from Nienburg via the B 6 to Bremen and Hanover. Due to the connections to the motorway network there, the B 215 is of great importance for supra-local economic, commuter and leisure traffic.
At km 0.427 (para. no. 90, station 0179) the B 215 crosses the Weser at river km 242.340.
The present project includes the new construction of the Weser bridge without demolition of the existing structure. The resulting relocation of the B 215 road and the conversion of the B 215/L 351/K 63 junction into a so-called "small roundabout" are not the subject of this tender.
The existing structure is a three-span bridge with a pillar, the replacement new building will be designed as a single-span bridge.
In the construction section, the speed is currently limited to 50 km/h in the course of the main road due to load-bearing capacity restrictions of the bridge.
The construction line begins west of the junction B 215 /L 351 /K 63 at construction km 10+000 (section 80, station 1203) and is then led in a right curve to the new roundabout, then in a left curve on the new Weser bridge and then ends in a right curve at the level of the access road to the gravel works at construction km 10+764 (section 90, Station 826).
A detailed description of the project can be found in the information document on the subject of the work.
NOTE: The ÖBÜ is awarded in a further VgV procedure. It is pointed out that the Client intends to award a separate contract and therefore the ÖBÜ and the service phase 8 will not be awarded to a contractor.
