PREDICTIVE MAINTENANCE IN CIVIL ENGINEERING
InSAR FOR CIVIL ENGINEERING
SkyGeo will configure an InSAR Monitoring solution for you: with millimeter accuracy,up to 25 years worth of history and 100,000’s measurement points per km², each with a graph of displacement over time.
Our data is often the best predictor for mean time before failure of the assets. Risk management practitioners use this for predictive maintenance.
Site Selection
Determine existing surface motion during site selection processes. Support the design and the optimisation of the ground instrumentation network.
SkyGeo provides unique support in reconstructing past ground motion patterns, which could potentially affect constructions.
Using a historical archive of satellite imagery, SkyGeo can identify unstable areas prior to construction and reconstruct their displacement to assist in the planning of new sites.
Monitoring with satellite data minimises survey time and cost compared to traditional measurement techniques.
Development
Monitor impact of construction activities on nearby buildings and infrastructure.
Complement traditional monitoring by extending motion measurements to a wider area.
Solve model uncertainty. The density and precision of measurements can be used to verify model predictions of ground displacement.
By mapping the evolution of ground displacement during construction, engineers can better understand the relationship between activities and the onset of any related settlement.
SkyGeo offers thousands of measurement points over large areas, at a fraction of the cost of traditional monitoring.
It also increases displacement information beyond excavation surroundings, to determine the extent of any displacement occurring within a wider area.
Maintenance
Assess the stability of assets over time to monitor that displacement remains within design parameters.
Control impact on assets of displacement occurring in adjacent areas.
Regular monitoring of post-construction displacement can identify structural weaknesses.
Identifying motion that could indicate a structural weakness helps engineers to determine if actions should be taken.
Moreover, InSAR Monitoring provides displacement maps to assess areas at risk.
Frequently Asked Questions
-
There is no universal displacement threshold that applies to every asset. A trigger should consider the rate and acceleration of movement, spatial extent, historical variability, measurement uncertainty, asset tolerance and consequence of failure. SkyGeo recommends defining these decision rules before monitoring begins, then using expert review to distinguish expected behaviour from a change that warrants inspection or additional instrumentation.
-
Start with the baseline, then identify persistent, accelerating or spatially unusual movement. Review data quality and geometry, combine the signal with asset condition, ground conditions and operational history, and rank the consequence of being wrong. The result should be an explicit action pathway: continue monitoring, inspect, instrument, investigate or intervene. SkyGeo’s Stedin case is a practical example of movement evidence being converted into maintenance prioritisation.
-
No. InSAR measures surface movement; it does not directly measure structural condition or provide a universal time-to-failure prediction. What it can do is reveal movement histories and changing patterns that may increase concern. Those observations become decision-grade when engineers interpret them with asset tolerance, construction history, geotechnical conditions, inspections and other monitoring before deciding whether action is required.
