Inspection and Test Plan for Method Statement – Hydrostatic Pressure Leak Testing of Domestic Water Supply Networks
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 leak-tightness and integrity of internal domestic water networks under hydrostatic pressure before concealment and commissioning.
Who uses this inspection and test plan
Contractor’s QA/QC and Site Engineers use it to control testing; Consultants use it for witnessing and acceptance.
When this ITP is prepared and submitted
After mechanical completion of a zone and before concealment or commissioning; repeated after any repairs affecting integrity.
Who receives or approves this ITP
Consultant/Engineer for review and approval prior to testing.
Inspection scope
Covers pre-test setup, calibration, isolation, filling and venting, pressurization, hold period monitoring, leak inspection, depressurization, and records.
Typical hold, witness, and review points
Hold: Pre-test setup; Hold: Main test acceptance; Hold: Documentation. Witness: Initial pressurization/stabilization.
Typical inspection records
Approved method/ITP, calibration certs, pre-test checklist, pressure-temperature logs, IRs, NCR/CCR (if any), final signed Test Certificate.
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.

| Review of method, ITP, and permits | Method, ITP, RA/Permit approved | Approved for construction/use | QA/QC Engineer / Consultant | Approved Method, ITP, RA, PTW |
| Material and component verification | Components installed and rated ≥ test pressure | Conform to specs/drawings | QA/QC Engineer | Inspection Request (IR), checklists |
| Instrumentation calibration check | Gauge class and range per EN 837-1; calibration valid | Valid ISO/IEC 17025 certs | QA/QC Engineer | Calibration certificates log |
| Pre-test setup and zone isolation | Blinds/caps installed; isolation verified; vents identified | Zone sealed; safe to fill | Site Engineer / Consultant | IR – Pre-test approval |
| Filling and de-aeration | Air expelled from high points; bubble-free flow | System fully water-filled | Site Engineer / QA/QC | Filling/vent log |
| Initial pressurization and stabilization | Pressurization ≤1 bar/min; stabilization 30 min | No sudden loss; no visible leaks | Site Engineer / Consultant (witness) | Pressure log |
| Main pressure hold test | 2-hour hold; readings per schedule; temperature recorded | No visible leaks; ΔP ≤0.2 bar after stabilization [Verify per project] | QA/QC Engineer / Consultant | Pressure/temperature log, IR |
| Post-test inspection and reinstatement | Controlled depressurization; safe drainage; reinstallation of components | No damage; area dry/clean | Site Engineer / QA/QC | Drain log, reinstatement checklist |
| Documentation and final acceptance | Review of logs, certificates, IRs | Consultant sign-off of Test Certificate | QA/QC Engineer / Consultant | Signed Test Certificate, marked-up drawings |
