The Project
Impressions from the project process
In the area of the double piers, 14 complete ACS self-climbing units with telescopic working platforms were used.
The carriageway of the Viaduc de Millau is positioned on up to 245 m high hollow piers.
Flexibly-adapted working platforms provided safe working conditions for all personnel even for the varying pier cross-sections.
The complete enclosure provided optimal protection for site personnel.
The cable-stayed bridge carries the carriageway at a height of up to 245 m across the valley. The tops of the steel pylons reach heights of 345 m.
The difficult shape of the structure required the adjustment or special preparation of the formwork elements for each concreting section.
Shuttering time was reduced through the use of only one anchor position. Optimal concreting results were achieved by the construction crews by using steel formwork.
For this type of construction, the right choice of formwork and climbing systems is the key to success. PERI has proven itself to be an extremely competent partner and the company´s huge project experience together with its tremendous commitment to the project has contributed greatly to the fact that we are ahead of schedule! The results that we could achieve with the ACS self-climbing system have completely fulfilled our expectations. While taking the extremely complex geometry of the structure into account, we could produce a concrete surface of the highest quality.
