NII screening
This is a preliminary engineering screening based on structured NII methodology.
Can this asset be inspected using Non-Intrusive Inspection?
Provide key asset details for a preliminary view of NII suitability and the appropriate next step in the workflow.

This is a preliminary engineering screening based on structured NII methodology.
How this assessment works
- Information
You provide asset context, operating conditions, damage mechanisms, and access constraints.
- Screening
Inputs are assessed against structured NII logic to form a preliminary suitability view.
- Strategy
The inspection objective and high-level approach are agreed before detailed planning fixes methods and coverage.
- Planning
Workpacks, acceptance criteria, and execution requirements are developed before field work starts.
This step covers Information through early Planning context. Execution, evaluation, and close-out follow in the full NII workflow. NAS delivers those stages, including physical on-site inspection, when you proceed.
Common questions
- What is this assessment?
- A preliminary engineering screening based on the same structured logic as early NII stages. It is not a substitute for detailed planning or execution scoping.
- What happens after screening?
- If inputs support it, NAS moves into strategy, workpack and planning, on-site inspection execution, analysis, and engineering close-out.
- Does NAS only advise after qualification?
- No. NAS delivers the full inspection workflow, including field execution and evaluation, when you proceed past screening.
- How does this relate to the NII process page?
- The form aligns with Information, Screening, Strategy, and early Planning. The process page shows the full sequence through Execution, Evaluation, and Decision.
