What needs to be clarified
The technical task is to compare agreed changes, claimed quantities and available evidence of completed work without selecting a breach in advance.
Materials to prepare
- The contract, estimate and correspondence on changes
- Acceptance records, delivery notes and material documents
- Work-stage photographs and access to the site
What to compare
- Separate versions of the assignment and establish the sequence of changes.
- Compare the actual material with supported documents and the work description.
- Identify quantities verifiable by inspection and areas needing further concealed-work information.
Possible outcome of the analysis
A document can set out a comparison table, observed discrepancies and technical answers within the examined scope.
Limits of the conclusions
A naming discrepancy alone does not prove poor quality; technical findings do not replace legal assessment of agreed changes.
