Trigger, activity, conclusion
A subcontractor, supplier, or haulier submits an invoice or payment application containing claims the main contractor's QS believes are inaccurate, duplicated, inflated, or relate to work not performed.
Retrieving and reviewing preserved footage and Gate Report records for the dates and locations relevant to the disputed claims — presenting that evidence to the subcontractor to resolve the dispute.
The invoice or payment application dispute is resolved. The main contractor pays only what is legitimately due. Court action or adjudication is avoided.
Workflow steps
- Step 01
A subcontractor, supplier, or haulier submits an invoice or payment application containing claims the main contractor considers suspicious or unverifiable.
Inferred - Step 02
Main contractor's QS reviews the application and identifies specific line items, quantities, dates, or amounts that appear inconsistent with site records.
Inferred - Step 03
PM, QS, or site manager identifies the relevant cameras, Gate Report records, and time windows that would capture the work, delivery, or attendance being claimed.
Evidenced - Step 04
the evidence system recordings accessed and scrubbed to the relevant periods. Local HFR recording export requested if higher resolution is needed.
Evidenced - Step 05
Gate Report ANPR data exported for the relevant period and cross-referenced with haulier or supplier claims.
Inferred - Step 06
Footage reviewed to verify or refute each disputed claim: worker presence, plant operating status, materials delivered, scope of work visibly completed.
Evidenced - Step 07
Observations and discrepancies documented — specific timestamps, headcounts, vehicle counts, screenshots, short clip exports.
Evidenced - Step 08
Footage clip or Gate Report export presented to the subcontractor or supplier — played directly from the evidence system or shared digitally.
Evidenced - Step 09
Subcontractor reviews evidence and typically withdraws, adjusts, or confirms the disputed element of the claim.
Evidenced - Step 10
Adjusted payment processed and commercial record updated. Footage retained. Where subcontractor disputes the footage interpretation, matter escalated to adjudication.

Evidence records
Trevor brought the subby into his office and showed him a video of what happened (on the evidence system), after which he returned the €70k. Trevor explained that if the video was not produced, the subby was willing to go to court.
We manage to save €100k in contractor overcharges.
Subcontractors claimed that they had delivered tables to site. We were able to see that they did not deliver any tables.
