• Ensure inspections and test records are completed before works are covered, insulated or progressed.
• Raise and manage NCRs, quality observations and defects, ensuring corrective actions are completed and formally closed.
• Drive progressive snagging and de-snagging of mechanical installations.
• Identify recurring quality issues and work with subcontractors to prevent repeat defects.
• Maintain accurate QA/QC trackers covering inspections, testing, NCRs, snags and outstanding documentation.
• Ensure redline drawings and as-built information are progressively maintained.
• Carry out system and area walkdowns with the project team, client, consultant and commissioning representatives.
• Coordinate closely with the Commissioning team to ensure mechanical systems are construction complete and commissioning-ready.
• Verify QA/QC prerequisites prior to L2/L3 commissioning, Functional Performance Testing (FPT) and Integrated Systems Testing (IST).
• Ensure outstanding quality issues are identified early and do not impact commissioning milestones.
• Support the compilation and review of test packs, commissioning records, O&M documentation, certificates and final handover information.
• Monitor the protection and preservation of completed mechanical installations through to handover.
• Produce regular quality reports covering outstanding inspections, defects, NCRs, documentation and programme risks.
