Continuous intelligence on structural behaviour
Structural Monitoring
Structural health monitoring provides continuous or periodic measurement of structural behaviour — tilt, displacement, crack movement, strain, vibration, and settlement. SiteOps designs and installs monitoring systems that transform structural risk management from periodic inspection to continuous data-driven assessment.
Our monitoring systems include digital tiltmeters for wall and foundation movement, crack gauges for distinguishing thermal from structural cracking, strain gauges for load monitoring, and vibration sensors for dynamic response. All data is transmitted wirelessly to cloud platforms with automated alert thresholds.
Monitoring is recommended where structural analysis indicates no immediate safety risk but uncertainty exists about whether the condition is stable or progressive. This is the "Monitor" tier of SiteOps' Make Safe and Monitor hierarchy — a justified and cost-effective alternative to immediate remediation, backed by continuous technical data.
SiteOps configures alert thresholds based on structural analysis for each installation. Three-tier alerting (attention, warning, alarm) ensures proportionate response. Monitoring data feeds into periodic technical reviews that track trends and update risk assessments.

Common questions about Structural Monitoring
How long does monitoring need to run?+
Crack monitoring requires at least 12 months for one full seasonal thermal cycle — allowing the engineer to distinguish temperature-driven movement (cyclical) from progressive structural movement (trending). Settlement monitoring typically runs 6–24 months depending on the trigger. Long-term heritage monitoring may run indefinitely as part of ongoing asset management.
What triggers an automated alert?+
SiteOps sets thresholds based on structural analysis specific to each installation. For example, a tiltmeter alert might trigger at 0.1° (attention), 0.3° (warning), and 0.5° (alarm). A crack gauge might trigger at 0.3mm growth (attention) and 1.0mm (alarm). Thresholds are customised — there are no generic factory defaults. All alerts include the measured value, the threshold breached, and recommended action.
Can monitoring replace repair?+
Monitoring replaces immediate repair only where structural analysis confirms no immediate safety risk. If a crack is stable (cyclic, not trending), monitoring provides the evidence that remediation can be safely deferred — saving significant cost. If monitoring detects progressive movement, it triggers remediation before a critical threshold is reached. Monitoring is a risk management tool, not a substitute for necessary repair.
