Designing a Structural Monitoring Program
Define the question, structure, sensors, data path, baseline and response process before collecting data.
What this topic covers
Define the question, structure, sensors, data path, baseline and response process before collecting data.
Core monitoring ideas
A program should state what behaviour is being monitored and why.
Sensor selection, sampling, communications and retention should follow the decision need.
Alarm ownership and engineering review should be defined before the first alert.
Interpretation limits
A baseline should include normal operational and environmental variation so ordinary change is not mistaken for damage.
Evidence and data quality
Monitoring evidence should feed inspection, engineering review and maintenance rather than exist as an isolated dashboard.
Lifecycle use
Lifecycle monitoring should be re-baselined after significant repairs, modifications or sensor-system changes.
