Digging line 16 of the Grand Paris Express
In Champs-sur-Marne, the teams, all from Fayat and managed by Razel-Bec, are carrying out work on Chelles station, the 5.3 km tunnel and 6 ancillary structures as part of the Grand Paris Express project. The earth pressure balance tunnel boring machine started from the Noisy-Champs centre siding, at the end of line 15, and worked its way northwards to the Bel-Air structure in the town of Chelles.
