Inspection and Test Plan for Method Statement – Intumescent Paint Application to Structural Steelwork

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 11 Jun 2026 Rev. 00 1 views
About this ITP: Defines inspections for each stage of intumescent coating works, including Sa 2½ preparation, environmental controls, WFT/DFT checks, adhesion testing, and documentation.

More than a static template

Unlike a downloadable Word or PDF template, this ITP is an AI-assisted editable starting point directly connected to its method statement. Every inspection activity, hold point, and acceptance criterion is structured and ready to adapt to your project.

  • AI-assisted customization — Tailor inspection activities and acceptance criteria to your specific project scope.
  • Linked method statement — This ITP is connected to the corresponding method statement describing the work sequence.
  • Multiple export formats — Download as a formatted PDF or editable Excel spreadsheet.
  • Editable starting point, not a final document — Review and verify all content against your project specifications and standards before use.

What you can customize

When you save this ITP to your account, every inspection row becomes editable. You can add, remove, or modify:

  • Inspection activity — Description of what is being inspected.
  • Inspection type — Hold point (H), Witness point (W), Review (R), or Monitor (M).
  • Responsibility — Contractor, subcontractor, engineer, or client.
  • Frequency — How often the inspection occurs.
  • Acceptance criteria — Referenced standard or specification requirement.
  • Records — Forms, test reports, or checklists required as evidence.

Why this ITP is used

To establish hold/witness points and objective acceptance criteria ensuring the coating achieves the required fire performance and durability.

Who uses this inspection and test plan

QA/QC inspectors, coating supervisors, third-party inspectors, and the Client/Engineer’s Representative.

When this ITP is prepared and submitted

Throughout the coating process from material receipt through final acceptance and handover.

Who receives or approves this ITP

Client/Engineer for approval prior to works.

Inspection scope

Material verification, substrate preparation, cleanliness/contamination tests, environmental monitoring, primer and intumescent application, thickness control, adhesion testing, topcoat application, and final documentation.

Typical hold, witness, and review points

Post-blast inspection (Hold), pre-intumescent application (Hold), total DFT mapping (Hold), adhesion testing (Witness), final acceptance (Hold).

Typical inspection records

CIRs, WFT/DFT logs, environmental logs, Bresle/dust/profile results, adhesion test reports, batch logs, calibration certificates, NCR/CARs, MDR.

Important approval note

This ITP is an AI-assisted editable starting point, not a pre-approved document. Before use on any project, all inspection activities, hold points, and acceptance criteria must be reviewed and approved by the relevant parties (superintendent, principal contractor, or client representative) in accordance with your contract and project quality plan.

Always verify acceptance criteria against your applicable drawings, specifications, and regulatory requirements. Hold points must be confirmed with the relevant authority before work proceeds past that point.

Frequently asked questions

Follow ISO 19840 or SSPC-PA 2: define measurement areas per member or per 10 m², with multiple gauge readings per area and mapping of results.

Select representative, non-critical areas agreed with the Engineer to avoid structural or aesthetic impact; repair test spots after testing.
