Value

Why this pack matters

The value case is grounded in evidence quality, decision speed, and measurable project outcomes.

Subcontractor performance turns captured reality into commercial evidence when teams need to verify what was done, when, and by whom.

Example metrics

  • Payment accuracy
  • attendance verification
  • quality evidence

Workflows in this pack

Very Common / HighSubcontractor Invoice & Payment Dispute Resolutioncloud recordings, local HFR recordings, and Gate Report ANPR data provide the primary independent evidence base for resolving billing disputes — verifying whether work was performed, materials delivered, quantities matched claims.Trigger: 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.Outcome: The invoice or payment application dispute is resolved. The main contractor pays only what is legitimately due. Court action or adjudication is avoided.40evidence10stepsEmodelVery Common / HighSubcontractor Labour & Attendance Verificationcloud recordings, the Recordings tab, and Gate Report ANPR data are used to verify subcontractor worker attendance — confirming arrival and departure times, headcounts, and overtime or weekend working claimed in labour returns.Trigger: A subcontractor submits a labour return, daywork sheet, overtime claim, or payment application that the main contractor's PM or QS believes may be inflated, inaccurate, or unverifiable.Outcome: The labour claim is verified or refuted by footage evidence. Dispute resolved without escalating to formal adjudication.40evidence10stepsEmodelVery Common / HighSubcontractor Work Quality & Defect Verificationthe evidence system camera footage and 360° captures used to document and verify the quality of subcontractor work — providing timestamped visual evidence of defects, rework, and non-conformances for formal quality management processes.Trigger: A quality inspection, milestone completion check, or defect liability dispute triggers the need to verify the condition of subcontractor work at a specific point in time.Outcome: Work quality is confirmed or defects are identified, documented, and assigned to the responsible subcontractor for remediation.20evidence9stepsEmodelCommon / HighPay Application / Progress Claim Visual Verificationcloud recordings and snapshot tools used to cross-reference visual state of works against percentage-complete claimed in subcontractor's monthly pay application.Trigger: Subcontractor submits monthly pay application asserting percentage of work complete that the main contractor's QS believes may be overstated or inconsistent with recent observations.Outcome: Pay application certified at face value (with visual confirmation), adjusted downward with evidenced justification, or returned for revision.10evidence10stepsEmodelCommon / HighSubcontractor Plant & Equipment Utilisation Verificationthe evidence system fixed camera recordings and Gate Report ANPR data used to verify whether specific plant/equipment items were physically present on site and actively deployed during periods invoiced.Trigger: Subcontractor/plant hire company submits invoice for plant utilisation on day-rate/time-rate basis; main contractor's QS/PM believes charged period includes time when plant was not on site or was idle.Outcome: Plant utilisation dispute resolved — invoice confirmed and paid, or reduced to reflect verified utilisation period.10evidence10stepsEmodelRare / LowUnion / Labour Compliance & Workforce Verificationcloud recordings and live camera feeds provide timestamped visual evidence of workforce composition, headcount, and on-site activity patterns — supporting union compliance verification.Trigger: A union compliance obligation, contractual workforce requirement, or production rate discrepancy prompts a review of on-site labour composition.Outcome: Workforce composition confirmed as compliant, or discrepancy identified, documented, and escalated.3evidence9stepsQqualitative
