Inspection and Test Plan for Method Statement: Deep Trench Excavation and Shoring Installation for Stormwater Mainlines
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 ensure excavation, shoring, and dewatering comply with design, safety, and environmental requirements and achieve dimensional and quality tolerances.
Who uses this inspection and test plan
Project managers, TWC, site engineers, QA/QC, dewatering specialists, HSE officers, and the Engineer/Client for verification.
When this ITP is prepared and submitted
From pre-start through dewatering commissioning, excavation, shoring installation, trench formation verification, backfill, and demobilization.
Who receives or approves this ITP
Engineer/Client Representative for review/approval prior to commencement.
Inspection scope
Covers documentation approvals, utility verification, dewatering setup and performance, shoring installation and monitoring, trench geometry, bedding/backfill density, and final area checks.
Typical hold, witness, and review points
Hold: utility clearance, first bay shoring, trench formation survey. Witness: dewatering commissioning, bedding and backfill density tests, shoring extraction.
Typical inspection records
ITP checklists, permits, survey reports, dewatering logs, water quality tests, density test results, daily HSE/TWC inspections, NCRs, and 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.

| Activity | Inspection / Test | Acceptance Criteria | Responsibility | Record |
|---|---|---|---|---|
| Pre-start documentation | Review of permits, TWD approval, lift plans | Approvals in place; permits current; risk assessments briefed | PM/TWC/QA-QC | ITP checklist, approvals |
| Utility clearance and potholing | Verification of locations vs as-builts | All utilities located and protected; hold point release | Utility Coordinator/Engineer | Pothole logs, redlines |
| Dewatering installation and commissioning | Drawdown test, pump flow check, discharge sampling | Water level ≥0.5–1.0 m below invert [Verify]; turbidity/pH within permit | Dewatering Subcontractor/Engineer | Commissioning sheet, water logs |
| Shoring system pre-use inspection | Dimensional and condition check; compliance with TWD | No damage; correct configuration; inspection tag current | TWC/Shoring Supplier | TWC checklist, photos |
| Pilot bay excavation and shoring installation | Witness placement, levels/verticality check | Verticality ≤1/100; spreader levels ±10 mm; clearances per TWD | Engineer/TWC | Inspection record |
| Trench geometry at formation | Survey of invert and width | Invert ±10 mm; gradient ±0.1%; width per design [Verify] | Surveyor/QA-QC | Survey report |
| Bedding (if in scope) | Level check; density testing | Thickness 100–150 mm; density ≥95% MDD [Verify] | QA-QC/Foreman | Test reports |
| Backfill (pipe zone and above) | Field density at defined frequency | Pipe zone ≥95% MDD; above-zone ≥98% to subgrade [Verify] | QA-QC | Density results |
| Ongoing shoring and HSE checks | Daily inspection of shoring, access, edge protection | No defects; ladders compliant; barriers intact | TWC/HSE | Daily checklists |
| Shoring removal and final area check | Witness extraction and backfill; surface condition | No voids/settlement; area safe and tidy | TWC/Engineer | Handover record |
