About this ITP: This ITP defines inspections, hold/witness points, and records for over-roofing projects using lightweight metal sheets over existing corrugated roofs.

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 ensure all critical inspections and tests are performed, recorded, and accepted before progressing, achieving safe and compliant installation.

Who uses this inspection and test plan

Site engineers, QA/QC, roofing supervisors, HSE managers, and client representatives.

When this ITP is prepared and submitted

From pre-start approvals through installation, watertightness checks, and final handover.

Who receives or approves this ITP

Client/Engineer for approval prior to commencement.

Inspection scope

Covers design approvals, asbestos controls, temporary works, pull-out tests, material inspections, installation stages, laps/flashings, and final acceptance.

Typical hold, witness, and review points

Hold: structural verification, pull-out tests, first-bay benchmark, final inspection. Witness: safety nets, spacer rails, flashings/gutters, watertightness as specified.

Typical inspection records

Approval registers, permits, pull-out test reports, torque logs, checklists, certificates (LOLER, EN 1263), material certs, photos, as-builts, warranties.

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

A typical frequency is at least 1 per 200 m² per purlin type with a minimum of six per roof area. Confirm project-specific frequencies with the designer and manufacturer.

Fastener torque must be within the manufacturer’s specified range and evidenced by periodic torque checks recorded in the torque log.

No. Hose tests are selective and only performed where specified and safe to do so, otherwise watertightness is confirmed by visual checks after rainfall.
