- Are there discrepancies between completion records and the actual scope of work?
- What relationship between the identified defects and completed work is supported?
How the work is carried out
- Checking the work list
- Inspection and analysis of records
- Checking technical discrepancies
Result
A report presenting checks of particular operations and the technical reasoning for identified defects.
What affects the conclusions
The scope of checking depends on the asset type; concealed operations require supporting materials.
