Inspection and Test Plan for Method Statement: HV Switching and Commissioning of RMU/Switchgear
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 ensure systematic, verified testing and safe energisation of HV RMU/switchgear in compliance with codes and project requirements.
Who uses this inspection and test plan
Contractor commissioning teams, HV Authorized Persons, Engineers/Consultants, and Utility/Authority representatives.
When this ITP is prepared and submitted
From pre-commissioning through post-energisation, culminating in handover.
Who receives or approves this ITP
The ITP is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the related work activity starts.
Inspection scope
Permits, mechanical/electrical integrity, IR/contact resistance, CT/VT, interlocks, relay settings, secondary/primary injection, SCADA SAT, phasing, energisation, post-energisation checks.
Typical hold, witness, and review points
Hold: relay settings approval, phasing, final pre-energisation, energisation. Witness: interlocks, secondary/primary injection, SCADA SAT, thermography.
Typical inspection records
PTW/LOTO logs, checklists, test reports (IR, ductor, CT/VT, injection), SCADA SAT sheets, settings files, phasing certificate, switching log, SOE, thermography, 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.
