Inspection and Test Plan for Method Statement: Geothermal Production Wellhead Equipment and Piping Installation

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

Published 29 Sep 2026 Rev. 00 3 views
About this ITP: This ITP defines hold and witness points for geothermal wellhead and piping works, including material verification, welding, RT, pressure testing, and insulation.

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 construction activities meet code, specification, and manufacturer requirements with documented verification.

Who uses this inspection and test plan

Contractor QA/QC, Site Engineers, NDE personnel, and Client/Engineer representatives.

When this ITP is prepared and submitted

From material receipt through final walkdown and turnover to operations.

Who receives or approves this ITP

Client/Engineer for review and approval.

Inspection scope

Covers materials verification, fit-up, welding parameters, NDE (VT/RT/PT/MT), PWHT, pressure testing, bolting, insulation/cladding, and final documentation.

Typical hold, witness, and review points

Master valve installation (H), RT interpretation (H), hydrotest (H), fit-up/welding parameters (W), insulation checks (W).

Typical inspection records

MTCs, PMI logs, fit-up and weld maps, NDE and PWHT reports, torque sheets, hydrotest packs, insulation reports, and MDR sign-off.

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.
