Tunneling | InSAR surveillance | Subsidence Claims
The Grand Paris Express, with 200 km of underground metro lines, is the largest tunneling project worldwide to use InSAR for monitoring the surface impact of this extraordinary urban development project.
- 68 new stations
- 200 km of underground metro lines
We have been providing InSAR surveillance at all stages of the tunnelling project:
- Historical analysis to complement existing geotechnical information and to settle subsidence claims
- Monitoring during works to assess the magnitude of surface motion and its real distribution
- Post-construction monitoring to scale back in-situ measurements
