• Support equipment and material specifications, vendor reviews, bid evaluations, and resolution of design questions during construction.
• Support project cost, schedule, quantity, and document-control commitments for assigned design work.
• Analyze field data in operating facilities and communicate discrepancies or risks to the responsible engineer or project manager.
• Set a good example with all rules and regulations to achieve 100% universal compliance with HS&E procedures and regulations.
• Participate in design reviews, constructability reviews, safety audits, surveillances, pre-startup activities, and project closeout.
