Our case studies

Improved durability was the key aim when Cohestrand was first deployed to construct the main cable of a 125 m-long suspension bridge south of Maastricht in Belgium.

Meticulous contingency planning and an innovative underpass bridge sliding technique were the keys that enabled a crucial railway line to reopen on time despite the British weather.

Connecting north and south Adelaïde, the South Road Superway includes a 2.8-km elevated roadway. Freyssinet proposed the balanced cantilever erection with launching gantry as the most beneficial construction method.

Concern over the magnitude of wind loading and potential for vibration that was predicted on the Bai Chay cable-stayed bridge in Vietnam led to the introduction of new, compact stay cables.

Located in an exposed offshore area subject to high-speed winds and to potential typhoons, the cable-stayed bridge had to be equipped with the most robust cable anti-vibration system and durable stay cables.

While incremental launching was the most appropriate method to construct the viaduct, it required complete rethinking to adapt to the project’s unusual configuration.

The project involves the construction of two 50m-long bridges above the light rail tracks, in non-traffic hours only, making the use of conventional erection method impossible.

A South Korean initiative to support new innovation has prompted the development of ultra-high-strength wire for parallel strand cables being installed on a cable-stayed bridge on the west coast.
