• Troubleshoot building system performance issues and coordinate or verify corrective actions.
• Maintain commissioning issue logs and track deficiencies through resolution.
• Lead or participate in commissioning progress and coordination meetings.
• Coordinate with owners, facility staff, contractors, engineers and controls providers.
• Prepare field reports, commissioning documentation and final reports.
• Support owner/operator training and project closeout activities.
• Provide technical support to project teams.
