According to our statement in the last annual report in December 2021, the renovation works on the railway bridge across the river Wiehl behind the Zunft-Koelsch brewery in Wiehl-Bielstein ("Zunftbrücke") had actually been completed in December 2021.

At the beginning of this year, the structural calculations and design documents were At the beginning of this year, the structural calculations and design documents were handed over to the test structural engineer by the engineering office. This essentially involved the inspection of the retaining construction of the bridge bearings; the old fastening studs of the bridge bearings had to be removed when the bridge bearings were dismantled.

Due to changes in the regulations, the structural engineer demanded the fastening of the bridge bearings to be reworked. As a result, there was a lengthy exchange of calculation documents between the engineering office and the structural engineer. In the end, it was clear that the bridge bearings had to be reinforced with additional fastening brackets.

The bridge bearings had to be reinforced with additional fastening brackets

The steel construction company "Send" installed the fastening clamps on the bridge in November, and in the meantime the test report of the structural engineer has also been received.

As a conclusion of this action, it can be stated: The engineering office should have reached an agreement with the structural engineer before starting the actual renovation work, then the time-consuming rework would have been avoided.

The additional effort for the additional construction and calculation work, as well as for the fabrication and installation of the fastening clamps was taken over by the engineering office.

hus, at the beginning of the new year, the completion of the rehabilitation work and the corresponding documentation can be reported to the district government of Cologne.
