Inspection and Test Plan for Method Statement: Establishment of Primary Survey Control Network

AI-assisted inspection and test plan connected to a method statement, with PDF and Excel export.

Published 23 May 2026 Rev. 00 1 views
About this ITP: This ITP defines inspections, tests, acceptance criteria, and hold/witness points for creating the primary survey control network. It ensures calibrated instruments, verified benchmarks, compliant accuracies, and complete records before setting-out.

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 that the survey control network meets specified tolerances and is properly documented and approved prior to use.

Who uses this inspection and test plan

Chief Surveyor, QA/QC Manager, Engineer/Consultant, and field survey crews.

When this ITP is prepared and submitted

From planning and monument installation through observations, adjustment, protection, and final handover.

Who receives or approves this ITP

Engineer/Consultant for review and approval.

Inspection scope

Covers plan approval, utility clearance, instrument calibration, GNSS and traverse observations, leveling closures, network adjustment, protection, and documentation.

Typical hold, witness, and review points

Hold: Control Plan approval, adjustment approval, final handover. Witness: utility clearance, monument installation, GNSS and leveling sessions, protection.

Typical inspection records

Approved plan, raw data (RINEX/TS/level), calibration certificates, processing and adjustment reports, protection photos, control register.

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

A stable adjustment with SEUW near 1.0, residuals within ±3.0, and point uncertainties within the specified horizontal and vertical limits.

Yes. At least 25% of points must be independently re-observed and compared against the adjusted coordinates within stated tolerances.

Final control register, drawings, raw observation files, calibration certificates, processing/adjustment reports, and transformation parameters.
