Inspection and Test Plan for Method Statement: Integrated Waterproofing and Root Barrier System for Extensive Green Roofs
AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.
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 verify that roofing assemblies are watertight, root-resistant, and properly configured for drainage before overburden is applied.
Who uses this inspection and test plan
QA/QC engineers, site engineers, roofing supervisors, ELD specialists, and Client/Consultant representatives.
When this ITP is prepared and submitted
From substrate acceptance through final inspection, with hold points at ELD and handover stages.
Who receives or approves this ITP
Consultant / Employer’s Representative
Inspection scope
Covers substrate checks, membrane installation and seams/DFT, outlets and terminations, ELD setup and testing, root barrier, drainage/retention, and filter geotextile.
Typical hold, witness, and review points
ELD setup and 100% testing (Hold), critical details (Witness), final inspection/handover (Hold).
Typical inspection records
ITP checklists, calibration certificates, material COCs, ELD reports, photographs, NCRs, as-builts, and manufacturer warranty pre-approval.
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.
