About this ITP: This ITP defines inspection points, tests, and acceptance criteria for a mass concrete raft foundation, including waterproofing, reinforcement, concrete placement, and thermal monitoring.

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 each critical step meets design and specification requirements, ensuring structural integrity and watertightness.

Who uses this inspection and test plan

Contractor QA/QC, Site Engineers, Testing Agencies, Engineer/Employer’s Representative, and Specialist Subcontractors.

When this ITP is prepared and submitted

From sub-base preparation through final acceptance, with hold and witness points at key milestones such as pre-pour and thermal monitoring.

Who receives or approves this ITP

Engineer/Employer’s Representative for review/approval prior to works.

Inspection scope

Covers blinding, waterproofing, waterstops, reinforcement, embedded items, concrete materials, placement, curing, thermal monitoring, and final documentation.

Typical hold, witness, and review points

Hold: Pre-pour readiness, final acceptance. Witness: Thermal monitoring reviews, fresh concrete testing, waterproofing sign-off.

Typical inspection records

IRs, delivery tickets, field and lab test reports, thermal data, as-built surveys, manufacturer approvals, calibration certificates.

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.

Frequently asked questions

Commonly one set of tests per 50 m³ or at least one per 10 trucks, including slump, temperature, and air (if specified). Verify per project ITP.

No. They apply to certain systems (e.g., spray-applied or specific geomembranes). Follow the manufacturer and project specifications.

Only if pre-qualified and approved in the ITP, with established strength–maturity calibration per ASTM C1074.
