Context
APRR-AREA, the second-largest motorway operator in France, is responsible for managing part of the national motorway network, which includes over 3,000 bridges. To enhance user experience and ensure safety while optimizing investment in bridge maintenance, APRR-AREA set out to develop a multi-year investment plan that incorporates a preventive maintenance strategy. This approach relies on capitalizing existing data through a digitalized asset reference system. Since 2018, Oxand has been supporting APRR-AREA with its software solution.
Our solution
- 01 Centralize scattered data on civil structures into a digitalized asset reference system
- 02 Conduct a component-by-component analysis for each bridge
- 03 Simulate component and bridge aging to anticipate maintenance needs and act preventively through generalized “campaigns”
- 04 Justify investment needs to inform leadership, reduce project costs, and minimize user disruption
- 05 Continuously monitor bridge conditions by linking safety audit data with Oxand’s investment planning and maintenance scenario simulation tool
What Oxand delivered
A transparent negotiation with the regulator
The optimised end-of-concession plan built and shared with the regulator, so budget optimisation and the contractual condition of the assets are negotiated on the same evidence.
Strategy and budget alignment
Alignment of executive strategy, allocated budgets, and actual technical needs
Shorter worksite durations
Improved customer experience through shorter worksite durations (preventive maintenance being less disruptive than corrective interventions)
Optimal investment timing
Visualization of cumulative costs to invest at the optimal time
Grouped renovation campaigns
Works grouped into renovation campaigns by component
In their words
“A solution that connects the technical teams, the finance teams and executive management alike”
“The APRR group has moved to strategic, sustainable asset management”
“Predicting ageing, planning the work on the different structural components with the end of the concession in view”
Questions about this reference
What does APRR-AREA manage?
Part of the French national motorway network, as the country's second-largest motorway operator, including over 3,000 bridges.
What was the objective of the work with Oxand?
To build a multi-year investment plan carrying a preventive maintenance strategy for the bridge portfolio, by capitalising the data the operator already held in a digitalised asset reference system. Oxand has supported APRR-AREA with its software since 2018.
How is a bridge portfolio of that size analysed?
Component by component. Each bridge is broken down and its components analysed individually, then their ageing is simulated so that maintenance needs are anticipated rather than discovered.
What is a renovation campaign?
Rather than treating each bridge on its own, works are grouped into generalised campaigns by component across the network. One mobilisation then covers many structures, which is what makes preventive work affordable at this scale.
How does preventive maintenance improve the experience of road users?
Preventive interventions are shorter and less disruptive than corrective ones. Grouping them into campaigns and choosing their timing from the cumulative cost curve is what shortens worksite duration on the network.
