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Result: Scattered data and silos between departments Multiple versions of AutoCAD drawings, sometimes outdated Time wasted in finding information Increased risk of errors on construction sites and interventions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
