Inspection and Test Plan for Method Statement: Deep Excavation Temporary Support Works Near Existing Structures and Services
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 that temporary works for deep excavation are installed, tested, and monitored to specification and risk is controlled at critical stages.
Who uses this inspection and test plan
Contractor’s site team, TWC, QA/QC, geotechnical engineer, specialists, and the Engineer/Employer’s Representative.
When this ITP is prepared and submitted
From pre-construction (PTD, baseline) through each excavation stage, shoring/anchor installation, to backfilling and demobilization.
Who receives or approves this ITP
The ITP is usually submitted to the client representative, consultant, resident engineer, or project management consultant for review and approval before the related work activity starts.
Inspection scope
Utilities clearance, instrumentation, dewatering, embedded wall installation, staged excavation, strut/anchor works, base stability, environmental discharge, and support removal.
Typical hold, witness, and review points
HP-1 PTD; HP-2 instrumentation baseline; HP-3 dewatering pump test; HP-4 wall alignment/toe; HP-5/7 staged levels; HP-6 strut preload; HP-8 anchor testing; HP-9 base stability; HP-10 removal.
Typical inspection records
PTD pack, piling/anchor logs, NDT reports, torque/preload sheets, monitoring snapshots, pump test data, discharge samples, base check certificate, 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.
