• Execute or supervise functional, operational, interlock, protection, and performance tests in accordance with approved procedures.
• Verify relay settings, protection schemes, control logic, trip circuits, alarms, interlocks, metering, and communication interfaces.
• Coordinate energization activities and ensure that all required permits, clearances, safety controls, and approvals are in place before equipment is energized.
• Identify, investigate, and resolve electrical faults, defects, test failures, and commissioning issues in a timely manner.
• Support system integration testing and interface verification with mechanical, instrumentation, control, automation, and utility systems.

Technical Coordination and Site Supervision

• Lead and supervise testing and commissioning engineers, technicians, subcontractors, and vendor representatives.
• Coordinate daily activities with construction and installation teams to ensure systems are complete and ready for testing.
• Liaise with project engineering, quality assurance, health and safety, planning, procurement, vendors, consultants, and client representatives.
• Review equipment condition, installation quality, accessibility, labeling, cable routing, terminations, and compliance before testing.
• Monitor manpower, tools, calibrated test equipment, materials, and specialist vendor support required for commissioning activities.
• Participate in site meetings, technical discussions, progress reviews, and coordination meetings.
• Provide technical guidance and resolve field-related issues while maintaining project quality and schedule requirements.

Quality, Safety, and Compliance

• Ensure all testing and commissioning activities are performed in compliance with approved procedures, project specifications, electrical codes, statutory requirements, and relevant international standards.
• Apply safe isolation, lockout/tagout, permit-to-work, switching, grounding, and energization procedures.
• Conduct or support pre-task briefings, risk assessments, toolbox talks, and job safety analyses.
• Stop unsafe work and report hazards, incidents, near misses, and nonconformities through the appropriate channels.
• Ensure all test instruments and equipment are suitable, properly calibrated, and used by competent personnel.
• Raise, track, and close inspection requests, punch-list items, nonconformance reports, and corrective actions.
• Maintain strict control of energized systems and ensure proper access restrictions, warning signs, barriers, and safety documentation are in place.

Documentation and Handover

• Prepare and review test sheets, inspection records, commissioning reports, energization certificates, test result summaries, and system completion dossiers.
• Maintain accurate records of test results, relay settings, equipment data, calibration certificates, approved procedures, and inspection approvals.
• Record deficiencies and coordinate their rectification with the responsible construction or engineering team.
• Support the preparation and review of as-built drawings, operation and maintenance manuals, equipment registers, and handover documentation.
• Prepare daily and weekly commissioning progress reports, including completed activities, constraints, risks, outstanding issues, and planned work.
• Participate in final acceptance testing, reliability runs, performance verification, and client demonstrations.
• Support operator and maintenance team training related to electrical equipment operation, protection systems, emergency procedures, and maintenance requirements.
