Structures monitoring
Topographic monitoring is applied for the analysis of deformations and geometrical variations in large-scale sites over time.
The benefits of a 3D laser scanning facility are unquestionable, where the monitoring of surfaces requires accuracy and a high level of detail, particularly in the case of non-regular geometrical forms.
Superior reproducibility of measurement will ensure the accuracy of controls between two points in time, in two measurement programmes which are staggered over time.
APPLICATIONS
- Control of subsidence, torsion, deformation and settlement
- Specifically for civil engineering structures: bridges, tunnels,
viaducts, etc. - Landslips, quarries, ditches, etc.
- Potentially affecting all areas: buildings, industrial facilities,
monuments - Comparison of successive states
- Real-time monitoring of deformation
