Trigger, activity, conclusion
A weather event or other external disruption causes a stoppage to a critical-path activity, and the contractor believes they are entitled to additional time and/or cost compensation.
Assembling and packaging documented visual and meteorological evidence that links specific adverse conditions to specific periods of demonstrable site inactivity — for submission as a formal EOT or prolongation claim.
The change order or EOT claim package is submitted. Owner reviews and claim is approved, negotiated, or disputed with a shared factual basis established by footage.
Workflow steps
- Step 01
A weather event or other qualifying delay event occurs on site, preventing or significantly impeding work on critical-path activities.
Inferred - Step 02
Site superintendent or PM logs the event in the daily site diary and weather log, noting the start/end time of the stoppage and the activities affected.
Inferred - Step 03
PM or planner identifies the relevant the evidence system cameras and time windows covering the affected work areas for the duration of the event.
Evidenced - Step 04
the evidence system recordings reviewed and footage clips extracted showing site conditions during the event — idle plant, workers sheltering, standing water, absence of productive activity.
Evidenced - Step 05
Compare/snapshot tool used to generate before-and-after images showing site conditions immediately before and during (or after) the event.
Inferred - Step 06
the evidence system built-in weather report for the site exported for the relevant period — capturing rainfall, wind speed, and temperature data to corroborate visual evidence.
Evidenced - Step 07
Footage clips, weather report, and programme analysis compiled into a formal change order or EOT package alongside the contract's baseline weather allowance comparison.
Inferred - Step 08
Package submitted to the owner or their PM/QS representative.
Evidenced - Step 09
Owner reviews the package — the visual evidence reduces or eliminates the owner's ability to dispute that the event occurred or caused a genuine stoppage.
Evidenced - Step 10
Change order or EOT approved (or parties enter negotiation with a shared factual basis established by the footage). Approved adjustment recorded in the contract.
Inferred
Evidence records
preserved footage and the weather report were used together to support the change order — the footage showed idle equipment and standing water, and the weather report confirmed the rainfall. The owner approved the claim without dispute.
Mike needed a local recording of Sunday, July 13th at 14:00 to 14:30 to show extreme weather — this ended up helping them go back to the subcontractor on rework of roof damage and internally to upper management on why a schedule change was needed due to weather damage.
Flood caused by council's pipes rather than contractor. Added insurance company to camera and were able to establish responsibility. Resolved in 30 minutes rather than 3 days.
