Case study:
HOW SEMITAN ENSURES THE RELIABILITY OF ITS DOCUMENTATION AND PROJECTS WITH MERIDIAN
For more than 40 years, SEMITAN has operated the public transport network of Nantes Métropole.
With more than 29.8 million kilometers traveled each year, 12,000 maintenance interventions carried out and more than 30,000 technical documents to manage, the documentary challenges are considerable.

THE CHALLENGES FACED BY THE SEMITAN BEFORE MERIDIAN
Before 2019, document management was based on disparate media: servers, CDs, floppy disks, paper archives.
Result: Scattered data and silos between departments Multiple versions of AutoCAD drawings, sometimes outdated Time wasted in finding information Increased risk of errors on construction sites and interventions
THE SOLUTION: A SINGLE DOCUMENT REPOSITORY WITH MERIDIAN
Since 2020, SEMITAN has chosen Meridian, configured according to its business needs.
The solution made it possible to:
Centralize all technical documentation
Ensure the traceability and security of versions
Streamline exchanges between maintenance, works, and engineering offices
Integrate AutoCAD and the Carl CMMS for direct access to documents in real time
CONCRETE BENEFITS
Thanks to Meridian, SEMITAN won in:
Reliability: up-to-date and secure information
Efficiency: instant access to the right documents
Collaboration: better connected and more responsive services
Security: interventions carried out on reliable data
With Meridian, SEMITAN now has a structured and reliable document system to support its asset management. The solution has made it possible to eliminate silos between departments, make technical information more reliable, and streamline exchanges with internal teams. SEMITAN is continuing its digital transition by strengthening control over its technical heritage, to optimize operational performance and improve the quality of service for Nantes users
