Our case studies

As the designer, supplier and installer of the stay cables and lightning protection system, Freyssinet assists Gefyra SA in the inspection and maintenance of the cables.

Given the very dense urban area and limited ground space available, replacement of the bridge steel deck had to be performed at heights, with consecutive lateral sliding operations.

On the Reunion Island, Freyssinet teams carried out the prestressing of the viaduct of the new coastal highway, the longest viaduct in France at 5,400 metres.

Deformations of significant magnitude caused the opening of the horizontal joint face slabs and parapet wall of the El Quimbo dam. They resulted in the rupture of the external joint waterstop at the contact upstream face slabs/concrete parapet wall and compromised the water tightness of the vertical joints of the parapet wall at various locations.

Cantilever erection by lifting frame was the preferred construction method to build the four precast segmental viaducts of the Lian Tang interchange highway located next to Kiu Tau, Fanling.

The Freyssinet teams designed, assembled and lifted the roof of the Volgograd Arena, a 1,600-t cable-stayed structure erected at 48 m. Cable-stayed structure using a Big Lift technique.

Construction of the library of Birmingham was originally conceived as a structural steel frame. During the tender period, and in order to realise the full value engineering benefits, the frame was changed to reinforced concrete with post-tensioned slabs and beams

A tensioning system to increase the water flow and speed up installation, and upstream preparation on a 1:1 scale replica of the canal: these were the keys to the successful waterproofing of the Larona hydroelectric plant.
