TRE Altamira, CLS’ subsidiary, monitors via satellite the Grand Paris Express project progress

Through its TRE Altamira subsidiary, CLS is taking part in the huge Grand Paris Express project. This project consists of 200 km of additional metro lines and 68 new stations, for a duration of approximately 15 years. The Société du Grand Paris commissioned our subsidiary to establish millimeter-level soil monitoring in order to monitor the impact of the construction of these infrastructures along the route as well as on adjacent areas.

On the occasion of a report broadcast on the french channel RMC Découverte on September 13, two CLS experts were able to explain the contribution of satellites in ground monitoring, as well as the unique aspect of this collaboration on a project of this magnitude.
