After a year and a half of monitoring, the monitoring devices were removed at the end of May from the tunnel of metro line 14 in the 13th arrondissement in Paris.
The objective was to monitor the movements and deformations of the tunnel during the excavation and the construction of three buildings of 8/9 floors with different underground floors, a few meters above the existing metro tunnel of line 14. This without disturbing the normal operation of line 14.
With the end of this monitoring, SWS Engineering successfully concludes almost two years of collaboration on this project with Vinci Construction France.
