Bridges
In 2001, following an international tender, the company was assigned the construction of five maintenance platforms for the Rion-Antirrion bridge. Each platform is installed under the bridge and in every bridge opening between the bridge towers.

The platforms provide access to the undersurface of the bridge to the staff in charge of its maintenance. Despite their weight (40 tons), the platforms can move with great accuracy along the bridge with speed 30 m/min. Furthermore, as the platforms are permanent bridge constructions, they have been built with the most rigid antifouling standards as far as both their steel framework and their mechanical equipment is concerned. The project was completed successfully despite its complex technical features satisfied all entities that were in charge of the quality control of all Bridge constructions.
