The Challenge
Dam movement outside the design envelope is found weeks late because readings are logged by hand and reviewed monthly. Instrument data, inspection notes and the design basis sit with three parties.
How It Works
- Reads piezometer and inclinometer feeds, satellite movement, inspection notes and design basis.
- Scores each reading against trigger action response thresholds and the historic envelope.
- Alerts the Engineer of Record with the reading, the threshold breached and the action due.
What It Removes
- Hand-logging piezometer readings into spreadsheets
- Monthly manual review of dam inspection notes
- Rebuilding the disclosure evidence pack each audit
Input Data RequirementsPiezometer and inclinometer time series, movement surveys, dam inspection reports, trigger action thresholds, design basis and construction records
Output FormatDaily facility status register per dam, threshold breach alerts routed to the Engineer of Record, and a standing tailings disclosure evidence pack
“We only find out a piezometer has been climbing when someone opens the spreadsheet at month end”
