Inspection and Test Plan for Method Statement: Installation of Air-Cooled Chillers on Rooftop Structural Steel Frames

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

Published 15 Jun 2026 Rev. 00 2 views
About this ITP: This ITP defines hold and witness points for safe lifting, precise placement, isolation, anchorage, and piping tests for rooftop air-cooled chillers.

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 critical inspections and tests verify compliance with design, codes, and manufacturer requirements before proceeding to subsequent stages.

Who uses this inspection and test plan

QA/QC engineers, site managers, lifting supervisors, structural engineers, client representatives, and vendor technicians.

When this ITP is prepared and submitted

From pre-mobilization document checks through lifting, installation, pipe testing, and pre-commissioning readiness.

Who receives or approves this ITP

Engineer/Consultant and Client’s Representative for review/approval.

Inspection scope

Documentation review, crane setup, structural frame survey, chiller placement, isolation settings, restraint anchorage, piping fit-up and pressure tests, and final readiness.

Typical hold, witness, and review points

Hold: crane setup verification; first anchor installation; pressure test. Witness: trial lift; isolator leveling; final walkdown.

Typical inspection records

Lift plan approvals, crane and rigging certs, survey/level reports, isolator logs, anchor logs and pull test reports, torque logs, pressure test certificates, checklists, as-builts.

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
Document approvals (drawings, lift plan, calculations) Verification of approvals prior to works All required approvals in place and current PM / QA-QC Approval matrix, transmittals

Frequently asked questions

Proof testing typically applies to a sample (e.g., 5–10%) of installed anchors or 100% where specified for critical fixings. Load and acceptance criteria must follow design and ETA/ESR guidance [Verify per project specs].

By measuring spring height/deflection against calculated values, confirming level tolerance, and recording snubber gaps. Records are kept on the Isolation Setting Log.

No visible leakage and pressure loss within the specified limit (commonly ≤ 1% after temperature stabilization) at 1.3–1.5× design test pressure and specified duration [Verify per project].
