Eiffage, through its subsidiary Eiffage Énergie Systèmes (consortium leader), and ENGIE Solutions have just won a contract to build the ventilation, smoke extraction and decompression system for lines 16 and 17 tunnels of the Grand Paris Express network a
The contract is worth a total of €58 million and is to be broken down as follows: €31 million for Eiffage Énergie Systèmes and €27 million for ENGIE Solutions.
Managed by Eiffage Énergie Systèmes, the contract covers the all line 16 from Saint-Denis Pleyel station to Noisy-Champs station, and the section between Le Bourget RER station and Triangle de Gonesse station on line 17. Altogether, these metro lines will cover 40 km of track and will include 12 new stations, as well as 42 associated structures.
The contract provides for supply, installation, and initial operation of:
- 67 ventilators with a power of 355 kW in the hoppers and 30 accelerators in tunnels with a power of 37 kW, as well as all the ventilation lines parts;
- gangways, safety rails and handling equipment needed for maintenance operations;
- all associated low-voltage equipment;
- the industrial automation, command-control cabinets, in-station smoke extraction units, Tunnel Ventilation local and server MMIs (man/machine interfaces)
In addition to the technical requirements, the contract covers complex site logistics arrangements in a dense urban environment, in line with a very short schedule.
There is a powerful environmental dimension to the project, the aim being to minimise the impact of works by complying with the provisions of the "Site environment" charter introduced by Société du Grand Paris. There is also a societal dimension: the consortium is committed to using 4,000 manhours of employment integration and 20% of the works will be entrusted to SMEs.
