Extra-ordinary bridge relocation in Berlin

For the relocation operation, the Wagenborg Nedlift team deployed a combination of techniques. First, a set of coupling pontoons with support beams on top. This created a stable surface for the jacking system that had to lift the bridge from the abutments.

This jacking system was only recently commissioned by Wagenborg Nedlift. The Fahlenbergbrücke project is therefore one of the first projects for this latest asset in jacking technology. The new jacking system uses jacking elements, is equipped with the latest features in jacking technology and is computer-controlled. A perfect system, therefore, for jacking a bridge like the Fahlenberg Bridge.

To release the bridge from the abutments in a controlled and safe manner, the client positioned additional jacks on both sides of the abutments. 

Around midday, the time had come and the crowds in attendance were treated to a fine show of craftsmanship by the bridge team. The bridge was silently raised and lifted from its abutments using the jacking system and jacks.

After the bridge was completely freed and secured accurately, the pontoons slowly moved towards the diversion route, 100 metres away. What precision steering by the tug skippers! Once there, the client first took care of some civil work on the temporary bridge supports.

The next day, the entire jacking operation took place in reverse order and the bridge was placed on the temporary abutments of the diversion route.

With as much calm and care as it had started the day before.
