Non-destructive testing, real-time monitoring, and rigorous reporting to understand how a structure is actually behaving — and whether intervention is needed.
Many decisions to strengthen or repair a structure are made based on visual observation alone — which is often insufficient. Structural health monitoring gives you objective data: is this crack growing or stable? Is this bridge still safe under current traffic loads?
NDVPL uses a range of NDT and monitoring methods appropriate to the structure type — from simple mechanical crack gauges for a historic church wall to full accelerometer networks for a heritage bridge under traffic loading.
Accelerometers and data loggers measure dynamic response under traffic, construction activity, or seismic events — detecting anomalies in structural behaviour.
Rebound hammer, ultrasonic pulse velocity, ground-penetrating radar, and endoscopy — assessing internal condition without damage to historic fabric.
Tell-tale gauges, demountable mechanical gauges, and crack width surveys with timestamped records to track whether cracks are active or stable.
Controlled load application and strain measurement to verify actual structural capacity — used for bridges, slabs, and heritage roof structures.
Systematic visual survey producing annotated drawings of all defects, material changes, and areas of concern — the starting point for any rehabilitation project.
Clear, well-documented reports with all findings, sensor data, interpretations, and maintenance or intervention recommendations.
We define what needs to be monitored, where sensors should be placed, and what data frequency is needed — calibrated to the specific risk profile of the structure.
Sensors are installed and a baseline reading is established under known conditions — the reference point for all future comparisons.
Data is collected over the agreed monitoring period, analysed for trends, anomalies, and threshold exceedances that indicate structural change.
A full monitoring report is delivered, including interpretation of findings and clear guidance on what — if anything — needs to be done next.
Describe the structure and your concern — we'll recommend the right monitoring or testing approach.
