The project includes the basic repairs to the outer harbors of the Schluesselburg lock on the Mittelweser. In addition to the replacement of the existing tail units and berths, the side embankments, embankments and service routes must also be planned.

As part of the contract, the existing plans are to be completed into a draft implementation document and the tender documents for the construction measures are to be created. In order to achieve this goal, the object planning in the scope of engineering structures, the structural planning and the technical equipment must be developed for the outer harbors. These services are supplemented by special services.
