SNCF Réseau awards Kadran its national 3D surveying framework agreement
Accurate and up-to-date infrastructure data has become essential for maintaining and modernising the French rail network. Against this backdrop, SNCF Réseau has selected Kadran for its national 3D surveying framework agreement.
Signed in January 2026, the contract covers the entire French rail network with an initial term of three years, renewable for two additional one-year periods. The total contract value may reach €13 million.
This appointment highlights Kadran’s expertise in capturing, structuring and enhancing geospatial data for rail infrastructure projects.
Delivering reliable data for rail projects
The framework agreement supports maintenance, renewal and development programmes across the network.
Services will contribute to projects involving:
- Track renewal and upgrades
- Overhead line systems (catenary infrastructure)
- Platform redevelopment
- Bridges and engineering structures
- Preliminary studies supporting future rail projects
To meet these requirements, Kadran combines existing SNCF Réseau datasets with targeted field surveys, ensuring the level of precision required for railway engineering projects.
Combining surveying and geospatial intelligence
One of the key strengths of this contract lies in the integration of surveying and geospatial information management.
Kadran’s services include:
- Establishment of topographic control networks
- Installation of Ground Control Points (GCPs)
- Registration and georeferencing of 3D point clouds
- Additional site surveys and field verification
- Production of engineering base plans
- Preparation of technical documentation supporting track and civil engineering studies
The ability to transform large volumes of geospatial data into practical engineering deliverables has become a key capability for major infrastructure operators.
Recognition of Kadran’s expertise
Ranked first at the conclusion of the procurement process, Kadran will benefit from priority positioning for assignments delivered under the framework agreement.
This recognition reflects:
- The quality of its proposal
- The complementarity of its surveying and geospatial expertise
- Its ability to mobilise teams rapidly across the country
It further confirms Kadran’s position as a leading provider of geospatial intelligence for railway infrastructure.
Supporting the future of the French rail network
By providing an accurate and continuously updated representation of its assets, SNCF Réseau strengthens its ability to plan interventions, secure construction works and optimise long-term asset management.
Through this framework agreement, Kadran contributes the reference data and geospatial intelligence required to maintain, renew and expand the French railway network.
This new success demonstrates Kadran’s ability to deploy its expertise at a national scale and support major infrastructure operators in delivering strategic, long-term projects.
