Grand Paris - Line 16 Lot 2

Comprehensive design studies for the new Paris metro

«Our teams have mastered the project’s technical challenges and the complex structures within a densely populated urban area.»
For the construction of lot 2 of line 16, the WE BUILD / NGE construction consortium has commissioned Lombardi to design the tunnels, stations, auxiliary structures and geotechnical aspects.

Line 16.2 features:

  • 11 km of tunnels, mechanically excavated using two tunnel boring machines,
  • 4 underground stations: Sevran Beaudottes (SEB), Sevran Livry (SEL), Aulnay (ALN) et Clichy Montfermeil (CMF),
  • 11 ancillary structures for rescue and ventilation purposes,
  • 7 cross passages linking the ancillary structures with tunnel.


Tasks entrusted to Lombardi Ingénierie:

  • Lead partner in the engineering joint venture,
  • Supervision and coordination of the technical design,
  • Geotechnical synthesis reports and G3 mission for the entire line,
  • Construction design of the 11 km of tunnels and segments, using fiber-reinforced concrete,
  • Construction design of 7 cross passages between ancillary structures and tunnel,
  • Vulnerability assessments of existing buildings,
  • Construction design of station entrances and exits and OAs,
  • Design of the Sevran Beaudottes and Sevran Livry stations,
  • Design of two ancillary structures.

The structures were modeled in 3D and the designs developed in BIM. Lombardi Ingénierie provided BIM coordination as part of its services.
