Inspection and Test Plan for Method Statement: Hydrostatic Pressure Testing of Chilled Water (CHW) Piping Networks

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

Published 16 Jul 2026 Rev. 00 2 views
About this ITP: This ITP outlines inspection stages, hold/witness points, acceptance criteria, and records for hydrostatic testing of CHW piping.

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 CHW piping is pressure-tested in accordance with code and project requirements with auditable records.

Who uses this inspection and test plan

QA/QC engineers, mechanical engineers, supervisors, commissioning teams, and Client/Consultant representatives.

When this ITP is prepared and submitted

After mechanical completion of a piping section and before insulation and pre-commission cleaning.

Who receives or approves this ITP

Client/Consultant for review and approval before testing.

Inspection scope

Document verification, calibration checks, site readiness, staged pressurization, 24‑hour hold monitoring, drainage, and documentation closeout.

Typical hold, witness, and review points

Calibration verification (Hold), reaching test pressure (Witness), start and end of 24‑hour hold (Hold/Witness), final document acceptance (Hold).

Typical inspection records

Approved test pack, calibration certificates, checklists, stage and hold logs, temperature records, witness forms, NCRs (if any), final test report.

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.

Inspection and test plan

Activity Inspection / Test Acceptance Criteria Responsibility Record
Review of IFC drawings, specs, and test calculations Check WP, Pt = 1.5 × WP unless limited by component rating Documents approved; pressures defined; boundaries identified [Verify per project] QA/QC Engineer / Mechanical Engineer Approved Test Pack
Calibration verification of gauges and thermometer Validity, range, and accuracy class ISO/IEC 17025 traceability; accuracy ≤1% F.S.; range 1.5–2.0 × Pt QA/QC Engineer Calibration Certificates
Pre-test installation inspection (vents, drains, supports, isolation) Walkdown with checklist All high points vented; low points drainable; equipment isolated; supports complete Mechanical Engineer / Supervisor Pre-Test Checklist & Photos
Filling and de-aeration Air expelled; initial pressure ~0.2–0.3 bar Air-free water at vents; no immediate leaks Supervisor / QA/QC Pre-Test Log
Staged pressurization to test pressure Visual inspection at each stage No leaks/sweating; gauges stable Supervisor / QA/QC Stage Hold Log
Stabilization soak 30–60 min stabilization Stable readings prior to 24-h hold QA/QC Engineer Soak Log
24-hour pressure hold monitoring Pressure & temperature logging No visible leaks; pressure within tolerance after temp correction [Verify] QA/QC / Supervisor Pressure-Hold Log / Datalog
Drainage and reinstatement Controlled discharge; component reassembly No environmental incident; system restored Supervisor Drain/Reinstatement Checklists
Final documentation and acceptance Completeness and approvals All records complete; Consultant approval QA/QC Engineer / Consultant Signed Test Report & ITP

Frequently asked questions

No visible leaks and pressure maintained within gauge tolerance after accounting for temperature effects, per project acceptance criteria.

Not mandatory unless specified. They are recommended for continuous, high-resolution records alongside manual hourly readings.

Only with written approval if permitted by project specifications; otherwise maintain the specified 24-hour hold.
