Instrumentation & Monitoring

Sterling deploys structural health monitoring and remote surveillance solutions that provide continuous asset performance data between periodic inspections. Our monitoring systems integrate with digital twins, enabling infrastructure owners to correlate sensor readings with specific structural elements and optimise intervention timing based on actual performance trends rather than age-based assumptions.

For high-value or critical infrastructure, we deploy tilt sensors to monitor track geometry during construction works (such as undertrack bores across Melbourne Metropolitan rail corridor), strain gauges and vibration monitors for load and deflection tracking.

Our monitoring approach supports predictive maintenance strategies by identifying deterioration trends early, validating the efficacy of repair works through before/after performance comparison, and reducing the frequency of physical inspections while maintaining safety assurance. For example, continuous monitoring of bridge bearings can detect abnormal movement patterns that indicate bearing failure risk before visible defects appear during biennial inspections.
