France – Engineering works and construction works – Autoroute A7 – traversée de Valence - Marché de Conception Réalisation pour la modification et la construction d’écrans acoustiques et pare-vues.

The contract covers Design/Build services (design studies + construction work) for the modification and/or construction of noise barriers on the A7 motorway, within the Valence urban area (Drôme), for a total length of approximately 5,500 meters of barriers (a total surface area of approximately 15,000 m²) and approximately 500 meters of privacy screens. Work will be carried out while the road (RD2007 to be diverted) and the motorway (A7) are in operation, both experiencing heavy traffic. The project includes: • Detailed design and synthesis studies; • Preparatory work, construction of the noise barriers, and related works; • External inspections and compliance checks; • Integrated project engineering includes: • Design studies, which must incorporate the client's architectural studies. The integrated engineering design team will approve the detailed design and synthesis studies and monitor the execution of the work through self-inspection. The integrated engineering design team will also organize and monitor the pre-acceptance operations. A full description of the tasks and work to be carried out will be specified in the project specifications.
