E. Documentation and Reporting

- Prepare and review commissioning plans, method statements, checklists, test reports, and commissioning procedures.
- Maintain equipment test records, punch lists, snag lists, and non-conformance reports.
- Review and validate OEM test certificates and commissioning documentation.
- Track testing progress, identify technical issues, and coordinate corrective actions.
- Prepare daily and weekly progress reports and maintain commissioning records.
- Support preparation of as-built drawings, operation and maintenance manuals, and final handover dossiers.

F. Coordination and Safety

- Coordinate with the client, consultant, main contractor, MEP contractors, OEMs, and commissioning authority.
- Attend commissioning meetings, resolve site technical issues, and monitor closure of outstanding observations.
- Ensure compliance with permit-to-work systems, lockout/tagout (LOTO), electrical safety procedures, and site HSE requirements.
- Ensure testing activities are conducted with approved risk assessments and method statements.
- Support client demonstrations, operator training, and final project handover.
