The challenge
While crews were stabilizing and reinforcing silos that were close to collapse, the plant needed to know at all times how the silos were behaving: tilting, settlement and crack growth.
Continuous monitoring with automatic alarms was the only way to work safely around them and to evacuate in time if needed.
Scope of works
- Tiltmeters on top of four silos, installed from a crane-hoisted man-basket
- Electronic crack meters on the cracks judged dangerous
- H-level liquid level system at the base to monitor differential settlement
- Sisgeo OMNIAlog data logger, programming, calibration and an alarm system
Outcome
The silos were monitored continuously throughout the works, with daily reports and alarms set to trigger an evacuation. Read the monitoring instruments case study and see our structural inspection and monitoring services.
