Ensure compliance with project specifications, drawings, and industry codes, including ASME Section I, Section VIII, B31.1, API standards, and applicable power industry requirements.

Conduct field inspections to verify weld quality, pressure testing, equipment alignment, grouting, torqueing, and mechanical completion documentation.

Coordinate closely with engineering teams to resolve RFIs, field design issues, constructability concerns, and technical challenges.

Maintain strict adherence to safety protocols, including heavy lift planning, confined space entry, hot work permitting, and mechanical system isolation.

Track progress, identify constraints, support schedule updates, and provide accurate reporting on productivity, manpower, and field risks.

Support commissioning and startup activities, including system flushing, cleaning, equipment testing, mechanical turnover packages, and readiness for energization or steam blows.

Build strong working relationships with subcontractors, inspectors, suppliers, and client representatives to ensure smooth field execution. #LI-CC1 #epjobs #naepjobs
