Variation & Scope Change Claim Validation

Description

cloud recordings, 360° captures, and Gate Report data are used to verify what work was or was not performed — enabling validation or refutation of a variation order claim.

Trigger

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).

Activity

Retrieving and reviewing historical preserved footage to establish a factual visual record of what work was performed, when, and by whom.

Conclusion

The variation claim is resolved using visual evidence — either validated, reduced, or withdrawn. Formal adjudication avoided.

Role detail

cloud recordings, 360° captures, and Gate Report data are used to verify what work was or was not performed — enabling validation or refutation of a variation order claim.

Steps (11)

1. 1A 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.
2. 2QS or PM reviews the claim and identifies the time period, location, and nature of the alleged change or additional work.
3. 3PM or site manager accesses the evidence system and navigates to the relevant date/time window and camera(s).
4. 4Footage reviewed to determine what work was performed, which trades were present, and whether scope deviates from the original contract.
5. 5Where the dispute concerns quantities, Gate Report data cross-referenced to verify truck movements, delivery counts, and timing.
6. 6Where the dispute concerns installation completeness, 360° captures from the relevant period reviewed to provide element-level visual confirmation.
7. 7Relevant footage clips, 360° frame exports, or Gate Report data extracts compiled as evidence.
8. 8Evidence presented to the disputing party — subcontractor, client, or their respective QS teams.
9. 9Disputing party reviews visual evidence and either withdraws, adjusts, or maintains their claim.
10. 10If 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.
11. 11Variation order settled — approved, adjusted, or closed — and project cost plan updated accordingly.

Evidence (3)

• “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%.”

  Anonymized evidence record 17.1

• “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.”

  Anonymized evidence record 17.2

• “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.”
