Inspection and Test Plan for Method Statement: In‑Situ Density and Moisture Content Testing of Earthworks Layers (Sand Replacement and Nuclear Methods)
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 assure each compacted layer meets specified density and moisture requirements relative to laboratory Proctor values.
Who uses this inspection and test plan
QA/QC engineers, field technicians, site engineers, and the Engineer/Consultant for witnessing and acceptance.
When this ITP is prepared and submitted
During construction of each earthworks layer immediately after compaction and prior to subsequent layer placement or surfacing.
Who receives or approves this ITP
Engineer/Consultant for review, witnessing, and acceptance.
Inspection scope
Document review, equipment standardization, random location selection, in-situ density/moisture testing, acceptance decision, and reporting.
Typical hold, witness, and review points
Selection of test locations; initial tests per lot; failing test investigations; lot acceptance sign-off.
Typical inspection records
Field density and moisture reports, Proctor curves, calibration/leak-test certs, nuclear gauge logs, RFIs/IRs, lot acceptance forms.
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 |
|---|---|---|---|---|
| Approval of method statement and ITP | Document review and approval | Approved documents prior to works | Project Manager / Engineer | Approved MS/ITP |
| Verification of Proctor reference | Check lab reports for MDD/OMC and compaction energy | Valid, approved Proctor for each material/source | QA/QC Engineer | Proctor reports |
| Daily equipment standardization/calibration checks | Gauge standard counts; balance zero; oven temperature | Within OEM/ASTM limits; certificates in date | Technician / QA | Daily check sheets; calibration certs |
| Selection/marking of test locations | Randomization and layout verification | Representative coverage per frequency; clear markings | Site Engineer / QA/QC / Engineer (witness) | Lot map; RFI/IR |
| In-situ density by Sand-Cone (ASTM D1556) | Hole excavation, sand mass, volume calc, moisture (ASTM D2216) | Duplicate within ±1.5% γd; computed %DoC ≥ specified; moisture within tolerance | Technician / QA Witness | Sand-cone field report; moisture sheet |
| In-situ density by Nuclear Gauge (ASTM D6938) | Backscatter/direct transmission counts; replicate readings | Counts within control limits; replicate δγd ≤ 30 kg/m³; %DoC ≥ specified; moisture within tolerance or verified by oven | Technician / RPO oversight / QA Witness | Gauge log; daily standardization; density report |
| Moisture content verification (referee) | Oven-dry moisture on selected samples | Within ±0.5% of nuclear/Speedy correlation (if applicable) | Lab Technician / QA | Moisture test report |
| Lot acceptance and reporting | Review compiled results vs criteria and frequency | All required tests pass; failures rectified and retested | QA/QC Engineer / Engineer | Lot acceptance certificate; NCR/CAR if any |
