Road networksAudit of the non-concession national road network
A first audit, carried out in 2017, highlighted the deterioration of the French non-concession national road network since 2006 and recommended increasing the resources allocated to its maintenance.
In the years that followed, budgets grew significantly, without reaching the levels recommended in 2017.
In this case, the client works with IMDM under the Asset management as a service model.
