Structural monitoring guide
Baseline Change Calculator
Calculate percent change from a user-entered baseline without defining an alarm limit.
Structural note: monitoring data is evidence, not a declaration of safety. Applicable codes, inspections and qualified structural engineering remain necessary for consequential decisions.
Percent change only; no structural limit is implied.
How to use this tool
These browser tools provide data-quality and trend arithmetic only. They do not establish structural safety limits, alarm thresholds, inspection intervals or allowable loads.
Results are based entirely on user-entered values and simplified arithmetic.
