Trigger, activity, conclusion
A subcontractor submits a variation order or change claim for additional work — or a scope dispute arises during a meeting when a party alleges work was done (or not done).
Retrieving and reviewing historical preserved footage to establish a factual visual record of what work was performed, when, and by whom.
The variation claim is resolved using visual evidence — either validated, reduced, or withdrawn. Formal adjudication avoided.
Workflow steps
- Step 01
A variation order claim or scope dispute is raised — subcontractor submits a VO claim, main contractor raises a VO to the client, or a scope dispute surfaces during a meeting.
Inferred - Step 02
QS or PM reviews the claim and identifies the time period, location, and nature of the alleged change or additional work.
Inferred - Step 03
PM or site manager accesses the evidence system and navigates to the relevant date/time window and camera(s).
Evidenced - Step 04
Footage reviewed to determine what work was performed, which trades were present, and whether scope deviates from the original contract.
Evidenced - Step 05
Where the dispute concerns quantities, Gate Report data cross-referenced to verify truck movements, delivery counts, and timing.
Inferred - Step 06
Where the dispute concerns installation completeness, 360° captures from the relevant period reviewed to provide element-level visual confirmation.
Evidenced - Step 07
Relevant footage clips, 360° frame exports, or Gate Report data extracts compiled as evidence.
Evidenced - Step 08
Evidence presented to the disputing party — subcontractor, client, or their respective QS teams.
Evidenced - Step 09
Disputing party reviews visual evidence and either withdraws, adjusts, or maintains their claim.
Inferred - Step 10
If claim is maintained despite footage evidence, package escalated to formal dispute resolution — but in the majority of evidenced cases, footage resolves the dispute before this stage.
Inferred - Step 11
Variation order settled — approved, adjusted, or closed — and project cost plan updated accordingly.

Evidence records
Main contractor used cloud recordings to verify the extent of groundworks completed by a subcontractor in a disputed earthworks variation claim — footage confirmed the excavation depth claimed was not reached, reducing the VO value by approximately 30%.
Aidan was able to pull out his phone, open 360 view on the mobile app and show that the works had already been done. This saved time and reduced the need for written documentation.
QS used the evidence system recordings to verify that a subcontractor's claimed additional works (temporary protection installation) were actually within the original contract scope — saving the main contractor from approving an unjustified variation order.
