Motorway concessions

Are you the concession holder of a road or motorway? A prime contractor on road construction projects? A contractor working on linear infrastructure?

Do you have a project for a new road, ringroad or bypass? Or for the widening (doubling the lanes) of an existing road, the rehabilitation or making safe of an existing road? Do you perform works on these types of projects?

We are familiar with your scheduling, availability of lanes and safety constraints, as well as the technical specificities of these studies.

The large number of areas of expertise we cover allows us to propose global solutions to the problems and issues of your project.
