Our case studies

As part of the design-build project for a set of precast segmental bridges, choice of the erection method was key to its achievement. Opting for the balanced cantilever erection with launching gantry made the difference.

Important savings in raw material and optimized execution planning were some of the many advantages of the alternative solution proposed by Freyssinet to build the Ihsaniye viaduct.

Conventional solutions for strengthening a critical viaduct in west London proved impractical and led to the development of a ‘plug and play’ post-tensioning system and bespoke erection equipment.

After more than 10 years of service, an assessment by Doncaster Council indicated that carriageway refurbishment and essential safety repairs were required for expansion joint replacement.

As part of a major port development project in Melbourne, Freyssinet has been awarded the dock restoration of the Webb Dock port facility.

To prevent corrosion on a 1,100-metre long structure, Freyssinet's teams installed a large-scale Impressed Current Cathodic Protection system (ICCP).

Featuring a combined concrete and masonry structure, the Sahasinaka viaduct was built in 1934. As one of the pier foundations showed signs of subsidence, structural strengthening of the bridge was conducted by Freyssinet.

Extending the lifespan of the viaduct by 100 years is what Freyssinet achieved after proposing a turnkey service to conduct heavy retrofitting works including additional prestressing, and completing them ahead of schedule.

Structural strengthening works were needed to renovate the ageing prestressed concrete preheater tower of a plant to increase its bearing capacity before installation of new equipment.
