The existing Waisen tunnel undercrosses the river Spree in the center of Berlin. It serves as an operating tunnel, connects the U5 and U8 lines and will continue to be an important element for the operation of the future metro network in Berlin. Built in 1917, it is a piece of contemporary history that is now showing its age.
In order to ensure functionality in the future, a thorough renovation is therefore necessary.
At the beginning of the planning work, the Waisen tunnel was surveyed by Amberg Technologies, and a point cloud was created from the survey data. On this basis and the existing inventory documents, a 3D inventory model was created, which represents the basis for further planning entirely using BIM.
The demands on the complex construction processes are very high due to the inner-city location, some of the neighboring buildings that are listed as historical monuments, and the need to maintain shipping operations on the Spree. The temporal dependencies are visible using a 4D BIM model, so that the construction processes can be checked and optimized.
Amberg Engineering has been working on the project in an engineering consortium, together with ZPP for the client Berliner Verkehrsbetriebe (BVG), represented by BVG Projekt GmbH since the beginning of 2021. Amberg Engineering handles the deputy overall project management, the overall BIM coordination as well as the structural planning and is significantly involved in the service phases 1 (basic investigation) to 6 (preparation of the tender award).
A demanding but exciting project in the center of Berlin. Thanks to the excellent engineering performance of everyone involved and the most modern planning tools a promising project!
