  • Coordinate with commissioning teams to support system readiness, integrated systems testing (IST), and turnover.
  • Ensure deficiencies are identified early and resolved prior to commissioning milestones.

Nonconformance & Corrective Action Management

  • Identify, document, and track mechanical nonconformances (NCRs) through closure.
  • Coordinate corrective actions with subcontractors and verify satisfactory resolution.
  • Analyze trends in defects and recommend corrective or preventive measures.

Trade & Cross-Discipline Coordination

  • Work closely with mechanical subcontractors to communicate quality expectations and resolve field issues.
  • Coordinate with Electrical, Fire Protection, Structural, and Architectural teams to ensure proper system interfaces.
  • Collaborate with Safety, Commissioning, and VDC/BIM teams to support coordinated system delivery.

Documentation & Reporting

  • Maintain accurate mechanical quality records, including:
  • Inspection and Test Plans (ITPs)
  • Inspection reports and test documentation
  • Deficiency logs and corrective action tracking
  • Utilize project management platforms such as Procore, BIM 360, and Bluebeam.
  • Provide regular quality status updates to the QA/QC Manager and project leadership.

Project Closeout & Turnover

  • Support preparation of mechanical closeout documentation, including O&M manuals and test records.
  • Verify mechanical systems meet quality and documentation requirements prior to owner turnover.
  • Assist with final inspections and turnover readiness reviews.

Additional Responsibilities

  • Perform other duties as assigned by the QA/QC Manager or Project Leadership.
