Inauguration of Paris metro extensions for Line 14 : NGE led France first tunnel boring operation under an operational airport.
Paris, June 24, 2024 – The northern and southern extensions of Line 14 were inaugurated today. For this project, NGE was responsible for the construction of 4 km of tunnel using a tunnel boring machine, with 3 km passing under the Orly airport area. This marked the first time in France that a tunnel boring machine operated under an operational airport. The work, which lasted 37 months, was completed without interrupting operations and within the planned timeframe, despite a pause during the Covid-19 pandemic.
For this project, NGE, in a consortium with Webuild, for RATP Group completed the final section of the southern extension of Line 14 between Pont de Rungis station and the Morangis maintenance and storage site.
The scope of work included 4 km of tunnel, the construction of three ancillary structures, and 700 meters of cut-and-cover and open trench.
The project was completed on time despite a one-and-a-half-month interruption during the Covid-19 pandemic, thanks to an efficient organization planned in close collaboration with RATP Group.
