In the course of execution, there were growing differences between the contractor, Wahl, and the City of Bonn as the client. Ultimately, these differences led to an extraordinary termination on July 22, 2024, and alternatively to an ordinary termination. As these are pending legal proceedings, no further details can be provided at present.

The City of Bonn intends to have the outstanding dismantling work carried out by a total contractor - with the aim of minimizing a possible extension of the construction period.
