Context
The client operates infrastructure assets under concession from the French State, including three exceptional structures that are strategic for the regional economy. In the medium term, these assets are due to be handed back to the State, and the client aims to return them in a condition that ensures future operation under optimal safety and comfort conditions. Oxand supports its clients in this process by implementing a robust, objective, and tailored multi-year maintenance program to ensure the infrastructure is handed over in good condition at the end of the concession period.
Our solution
- 01 Collect and analyze existing data on infrastructure assets (civil engineering structures, roadways, technical and operational buildings, etc.)
- 02 Consolidate the data using new diagnostics (concrete aging in structures, fatigue of metal components, condition of safety barriers, suspension cables, and stay cables, etc.)
- 03 Define maintenance policies
- 04 Model the aging of infrastructure assets

Questions about this reference
What is the objective of the engagement?
To hand three exceptional structures back to the French State at the end of the concession in a condition that allows future operation under proper safety and comfort — which requires a multi-year maintenance programme built for that deadline.
Why does the end of a concession change the maintenance question?
Because the operator is not planning for its own horizon but for the condition it has contracted to hand over. Works are therefore sequenced against a fixed date and an agreed state, not against the operator's own convenience.
What is assessed on the structures?
Existing data on the civil engineering structures, roadways and technical and operational buildings, consolidated with new diagnostics: concrete ageing, fatigue of metal components, and the condition of safety barriers, suspension cables and stay cables.
What is produced from that assessment?
Maintenance policies, and models of how the assets age, which together allow several asset management scenarios to be projected rather than a single programme proposed.
What does the concessionaire hold at the end?
An objective and concise view of how asset condition and the associated risks evolve, and the projection of several management scenarios against the handover date.
