How can a manager request corrective work after the report?
Use the inspection findings as the scope and ask the contractor to identify the work addressing each finding. This is practical reasoning, not legal advice and not a finding from any agency.
- Use the inspection findings as the scope and ask the contractor to identify the work addressing each finding.
- Ask who will handle the required filings and retain the completed report with submission evidence.
- Keep urgent corrective work separate from optional improvements in the written request.
