Context
The Pyrénées-Atlantiques departmental council looks after close to 1,500 engineering structures — arches, reinforced slab bridges and other families besides, of widely differing ages, the oldest of them more than a century old. The department knows its estate well. What it wanted was to build on that knowledge: to turn what the teams carry into a base its decisions can rest on, and be sure of doing the right work at the right time.
Our solution
- 01 Standardise the data The data on the structures standardised and consolidated, so a bridge and an arch can be compared on the same basis.
- 02 Model the risks The risks attached to each structure modelled, which turns a dated survey into a dynamic view of condition.
- 03 Build maintenance scenarios Maintenance policies built as scenarios, budget constraints included.
- 04 Draw up the multi-year programme A multi-year investment programme built from those scenarios.
- 05 Embed the tool in the teams Teams trained and accompanied, so Infrasim™ keeps being used after the engagement ends.
What Oxand delivered
A plan ordered by risk
A dynamic software solution producing a multi-year investment plan that prioritises risk.
Visibility on ageing
A solid view of the condition and ageing of the structures — the base for a structured, predictive approach to the estate.
Costs and risks held
Control over the costs and the risks tied to operating the structures.
Questions about this reference
What estate does the department manage?
Close to 1,500 engineering structures of very different families — arches, reinforced slab bridges and others — and of ages just as varied, the oldest beyond a century.
Why model rather than inspect?
An inspection tells you the condition of a structure on a date. A model tells you how that condition will move, and therefore when to act. That shift from survey to projection is what lets the right work happen at the right time rather than on the calendar.
What is Infrasim™?
Oxand's solution for infrastructure. Here it carries the risk modelling of the engineering structures and the construction of the multi-year investment programme.
What does the department hold at the end?
A multi-year investment programme ordered by risk, and teams trained to keep it alive — the engagement installs the tool in the organisation rather than delivering a report.
