• Support planning activities for work on operational facilities and live plant environments.
• Track defects, punch-list items and outstanding actions through to completion.

• Act as the client's technical representative during commissioning activities.
• Attend commissioning meetings, readiness reviews, inspections and testing activities.
• Review commissioning records and objective evidence to verify compliance with project requirements.
• Challenge deviations, incomplete documentation or unsupported close-out requests.
• Ensure commissioning activities are completed safely and in accordance with company procedures and industry standards.
• Support project acceptance, handover and operational readiness activities.

• Review engineering and commissioning documentation including:
  • Control philosophies
  • Functional Design Specifications (FDS)
  • Cause & Effect documentation
  • SAT/FAT procedures
  • P&IDs
  • Loop drawings
  • Alarm schedules
  • Functional safety documentation
• Provide commissioning input during design reviews, HAZOPs, LOPAs and technical workshops.
• Support design teams to ensure operability, maintainability and testability requirements are incorporated.

• Support and oversee:
  • Factory Acceptance Testing (FAT)
  • Site Acceptance Testing (SAT)
  • Static commissioning
  • Dynamic commissioning
  • Functional testing
