About this ITP: This ITP sets hold/witness points and acceptance criteria for trenching, bedding, pipe jointing, surround compaction, backfilling, and air testing.

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 verify that stormwater pipe installation meets design, standards (EN 1610/BS EN 1916), and contract requirements before covering works.

Who uses this inspection and test plan

Contractor QA/QC, Site Engineer, TWC, HSE, and the Engineer/Client for surveillance and acceptance.

When this ITP is prepared and submitted

From material receipt through trenching, laying, backfilling, and testing, prior to reinstatement and handover.

Who receives or approves this ITP

Engineer/Client Representative for approval and witnessing.

Inspection scope

Covers material compliance, trench stability and support, bedding, joint assembly and alignment, compaction, air testing, and as-built survey.

Typical hold, witness, and review points

Hold: Bedding approval; Section air test. Witness: First joint, surround to 150 mm above crown, backfill layers.

Typical inspection records

Material certs, trench inspection logs, bedding/compaction records, air test certificates, calibration certs, as-built survey, NCR/CAR if any.

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 receipt – pipes and gaskets Check CoC/CoA; visual for defects; confirm joint type/ring size Conform to BS EN 1916/BS 5911 and BS EN 681-1; no damage to sealing faces QA/QC Engineer / Foreman Material inspection form; delivery notes
Trench excavation and support Check width, depth, support per TWD; spoil setback; access/egress Stable, shored trench per TWD; dimensions within tolerance; safe access TWC / Foreman / HSE Trench inspection log; permit-to-excavate
Bedding preparation (Class B) Thickness and profile; material compliance ≥100 mm thickness; level ±10 mm; aggregate per BS EN 13242 QA/QC / Site Engineer Bedding inspection sheet; test reports
Pipe laying – jointing and alignment Witness mark, ring seating, laser alignment, invert levels Joint fully home or gap per spec; ring not displaced; line ±10 mm; level ±6 mm/10 m [Verify] Site Engineer / Foreman Joint checklist; as-laid level sheet
Sidefill and surround compaction Method compaction; density testing if specified Void-free haunch; surround to ≥150 mm above crown; density per spec [typ. ≥95% MDD] QA/QC / Foreman Compaction records; photos
Backfill above pipe zone Field density tests at specified frequency Compaction meets specification; no damage to pipeline QA/QC / Foreman Density test reports
Air testing of pipeline section Low-pressure air test per EN 1610 (pressure/time by DN) or ASTM C969 if specified Meets code allowable pressure drop/time or infiltration/exfiltration rate [Verify] QA/QC / Site Engineer; Engineer witness Signed test certificate; gauge calibration
As-built survey Check inverts, line, cover vs design Within specified geometric tolerances [Verify] Surveyor / QA/QC As-built drawings, CSV/XYZ files

Frequently asked questions

Typically each section between manholes or test points is tested. The Engineer may approve consolidation of short sections. [Verify per project].

Often method compaction is specified due to access limits; density tests may be required above the pipe zone or as practicable. [Verify per spec].
