About this ITP: Comprehensive ITP for dry-drilled bored piles, defining hold/witness points, acceptance criteria, and records for each construction stage.

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 control workmanship and verify that each pile meets design, safety, and quality requirements before proceeding to subsequent stages.

Who uses this inspection and test plan

Contractor’s QA/QC, Piling Superintendent, Engineer/Employer’s Representative, Testing Laboratory, and HSE team.

When this ITP is prepared and submitted

Applied from setting out through drilling, base verification, cage placement, concreting, trimming, and integrity testing.

Who receives or approves this ITP

Engineer/Employer’s Representative for review and approval prior to piling operations.

Inspection scope

Covers setting out, platform certification, plant readiness, casing, drilling, base cleanliness/dryness, reinforcement, concrete tests, placement monitoring, trimming, and integrity testing.

Typical hold, witness, and review points

Hold: platform certification, base cleanliness/dryness, reinforcement before pour. Witness: casing verticality, drilling depth, concrete tests, concreting progress, pile head trimming.

Typical inspection records

Survey/as-built reports, piling logs, base inspection checklists, rebar inspection sheets, concrete test reports, batch tickets, integrity test reports, photos, 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
Setting out verification Check pile coordinates vs grid; Witness point Within ±75 mm of design centerline or per spec Surveyor / QA Survey report; IR approval
Piling platform certification Review platform certificate; visual inspection; Hold point Certified safe bearing and drainage; no soft spots Contractor / Engineer Platform certificate; checklist
Plant and lifting gear Verify inspection tags; load charts; daily checklists Valid certifications; no defects Contractor / HSE Plant logs; lifting gear register
Temporary casing installation Check verticality and embedment; Witness Verticality ≤ 1:200; sufficient embedment to prevent collapse/inflow Piling Superintendent / Engineer Casing log; photos
Drilling to depth Depth measurement; verticality; spoil inspection Design depth achieved; diameter not less than design; verticality within tolerance Piling Superintendent / QA Piling log; depth record
Base cleaning and dryness check Weighted tape/camera check; Hold point Loose debris ≤ 50 mm; standing water ≤ 50 mm or inflow ≤ 20–50 L/min [Verify] QA/QC / Engineer Base inspection checklist; IR approval
Reinforcement cage inspection Check bar size/spacing, splices, cover spacers, cage length Per approved bar schedule; cover ≥ 75 mm; splices/couplers approved QA/QC / Engineer Rebar inspection report; photos
Fresh concrete tests Slump (ASTM C143/EN 12350-2), temp (ASTM C1064), air (ASTM C231 if specified); sampling (ASTM C31/EN 12350-1) Slump 150–220 mm [Verify]; temp 5–32°C; air per mix design QC Technician Concrete test reports; batch tickets
Concrete placement monitoring Continuous pour; head maintained; casing withdrawal control No interruptions; no segregation/soil inclusion; volume within +10%/-5% vs theoretical [Verify] Piling Superintendent / QA Pour log; site diary
Specimen curing and strength tests Curing and compression tests (ASTM C39/EN 12390-3) 28-day strength ≥ specified f'c; early age results per requirement QC / Lab Lab reports
Pile head trimming inspection Visual/hammer sounding; rebar exposure; level check Sound concrete at cut-off; level ±10 mm; bars per detail QA/QC / Engineer Pile head inspection report
Integrity testing (PIT/CSL) if specified Low strain PIT per ASTM D5882; CSL per ASTM D6760 where tubes exist No major defects; acceptance per Engineer criteria/spec Specialist / QA / Engineer Integrity test report

Frequently asked questions

Yes. The Engineer may add project-specific hold/witness points, which must be reflected in the approved ITP before work starts.

Raise an NCR, stop the activity, and agree corrective actions with the Engineer before proceeding. Document any retests or remedial works.
