Our case studies

Installation of a cable-stayed bridge by rotation over a heavily trafficked motorway whose configuration does not allow for a traditional incremental launching construction method.

Creation of a pedestrian tunnel under the railway tracks of the Vendôme metro station in Montreal by Autoripage.

The construction of a station located underneath a Paris shopping centre required the taking up of a load of a frame assembly of some 100,000 tonnes, thanks to an innovative jacking system.

Use of prestressing to ensure sustainable waterproofing and optimise the sizing of a tall tank digester.

Reinforcement of the ExxonMobil offshore platform in Canada with 2,400 tonnes of post-tensioning to ensure waterproofing and iceberg-resistance of its concrete structure.

The unique launching procedure that was employed to build the deck of France’s prestigious Millau Viaduct put construction and cable-stay technology to the test.

In South West France, where environmental conditions can create maintenance headaches, durability was a high priority for the authority commissioning a new suspension bridge.

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.
