Inspection and Test Plan for Method Statement: Installation of Carbon Steel Chilled Water Piping with Grooved Mechanical Couplings

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

Published 15 Jul 2026 Rev. 00 3 views
About this ITP: This ITP defines hold/witness points, inspection activities, and acceptance criteria for CHW piping installed with grooved mechanical couplings.

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 each stage of grooved piping installation meets dimensional, assembly, and pressure integrity requirements.

Who uses this inspection and test plan

Contractor QA/QC, Site Engineers, and the Client/Consultant for verification and approvals.

When this ITP is prepared and submitted

From material receipt through installation, flushing, pressure testing, and handover.

Who receives or approves this ITP

Client/Consultant

Inspection scope

Material verification, groove geometry, coupling installation and torque, alignment/supports, flushing, and hydrostatic testing.

Typical hold, witness, and review points

Groove setup trial (W), coupling torquing spot checks (W), flushing (W), hydrotest (H), final documentation (W).

Typical inspection records

MIR, IR/ITR forms, groove inspection sheets, torque logs, calibration certs, flushing reports, hydrotest certificates, 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
Material receiving (pipe, couplings, gaskets, supports) Verify make/model/ratings; visual for damage/coating; review MTCs and approvals Materials match approved submittals; markings traceable; no damage/out-of-roundness > 1% OD [Verify] QC Inspector / Consultant (W) MIR; Receiving inspection report; MTCs
Roll grooving setup trial Check roll set selection; produce trial groove; measure A/B/C/D/flare All dimensions within manufacturer/AWWA C606 tolerance; no cracks/tears; acceptable flare QC Inspector / Consultant (W) Groove setup sheet; IR
Production groove inspection Sampling inspection of groove geometry; surface finish; out-of-roundness Within tolerance; finish smooth; out-of-roundness ≤ 1% OD [Verify] QC Inspector Groove inspection sheets
Gasket type and lubricant check Confirm EPDM gasket, size, condition; verify approved lubricant batch Correct grade; no defects; lubricant compatible (no petroleum) QC Inspector Material traceability; IR
Coupling installation and bolt torquing Visual engagement of keys; gasket position; even tightening; torque measurement Metal-to-metal housing contact (where applicable); torque within manufacturer range; torque marks applied; no gasket extrusion beyond limit QC Inspector / Consultant (W) Torque log; IR
Alignment and support spacing Laser/stringline alignment check; verify support spacing vs. schedule; anchors/guides Deviation ≤ 3 mm per 3 m (typ.) [Verify]; spacing per approved schedule; rods vertical; isolation pads as specified QC Inspector / Site Engineer Alignment & support checklist; IR
Flushing/cleaning Flow verification; discharge clarity; debris collection Velocity ≥ 1.5 m/s (typ.) [Verify]; discharge clear; turbidity ≤ 5 NTU or per spec QC Inspector / Consultant (W) Flushing report; permit to discharge
Hydrostatic pressure test Pressurize to specified test pressure; hold for duration; leak/pressure drop monitoring No visible leaks; pressure maintained within allowable drop per ASME B31.9/project spec QC Engineer / Consultant (H) Pressure test certificate; gauge/pump calibration certs
Final inspection and documentation Close-out of punch-list; documentation completeness All IRs approved; NCRs closed; records complete and accepted QC Engineer / Consultant (W) Handover dossier index
