Multi-service network and monitoring systems for Line 18 of the Grand Paris Express

Eiffage Énergie Systèmes and VINCI Energies will provide the multi-service network and monitoring systems for Line 18 of the Grand Paris Express in a contract worth €60 million.

The consortium led by Eiffage Énergie Systèmes (leader) and VINCI Energies won the contract to supply, install and maintain the multi-service network and spaces monitoring systems for Line 18 of the Grand Paris Express for a total amount of €60 million.


The contract, which was awarded by the Société du Grand Paris, covers all of Line 18, a major component of the Grand Paris Express network that links Orly airport to the Versailles Chantiers station, with 35 kilometers of track, 10 stations and an 8 kilometers inter-station section.
It provides for:

  • the installation of the line’s multi-service network, which is the backbone of the Société du Grand Paris’ information systems;
  • the creation of monitoring systems that include video surveillance, access control, intrusion detection, telephony and intercom capabilities both along the track and in the trains.

The Eiffage Énergie Systèmes teams responsible for project management will work with VINCI Energies, and in particular with its Axians subsidiaries, to integrate this complex architecture of critical safety and security systems. The contract also includes an overall assessment of the cybersecurity policy and measures of the Grand Paris Express systems for Line 18.


Design and engineering work is already underway for the initial phase of the project to allow the opening of the Orly station. The various systems will be integrated in three phases and will be put into service progressively with final completion scheduled for 2030.


The consortium has undertaken to entrust 20% of the work to VSEs and SMEs and to reserve at least 10% of working hours for people currently away from employment.
