Design operation on STEEL in Saint-Etienne

Eiffage Route's teams took charge of the external developments by building, among other things, the retaining walls, service roads, infiltrating parking areas and asphalt mixes, on land that had previously been cleared and excavated by Eiffage Génie Civil.
 
At the same time, Eiffage Énergie Systèmes teams carried out the work on the dry networks and parking lot lighting.
 
In all, some 60 employees were mobilized to carry out this project, which reinforces the modern image of the design capital, which is currently undergoing a major urban transformation.
