First TBM for Line 15 West delivered - On May 28, 2025, Herrenknecht finished the first TBM EPB for the Intencites15 consortium, led by VINCI Construction Grands Projets, and the Societe des Grands Projets. The TBM is 110 m long, 1,700 t in weight, has a 9.87 m diameter shield and 136 cutting edges. It will be involved in the construction of Line 15 West excavation for the Grand Paris Express.
The TBM will now be dismantled and transported to Nanterre La Folie from where - in November 2025, once reassembled - it will begin excavating the 8.3 km of tunnel towards Courbevoie, passing through La Defense. In Courbevoie it will be dismantled, taken back to Nanterre from where it will restart towards Rueil-Malmaison.
In the meantime, a second TBM is under construction that will excavate the remaining 5.1 km of tunnel between Sevres and Rueil-Malmaison.
The Intencites15 consortium won the EUR 2.71 billion contract in 2023 to build line 15 West between the Pont de Sevres and La Defense stations.

The delivery of the S-1422 TBM, the first for line 15 East of the Grand Paris Express project, began on May 26 at the Agnes shaft at the Aubervilliers construction site.
