FEED (Front-End Engineering Design) develops detailed design basis, equipment specifications, cost estimates, and execution plans that enable project sanction and detailed engineering. FEED bridges conceptual design and execution, reducing uncertainty and establishing project scope, cost, and schedule baselines.

FEED deliverables include process flow diagrams, piping and instrumentation diagrams, equipment specifications and data sheets, plot plans and 3D models, material selection and corrosion management philosophies, and engineering estimates typically targeting ±10-15% accuracy. These deliverables define what will be built and provide basis for detailed engineering.

For fabrication-intensive projects, FEED includes equipment sizing and preliminary design, fabrication and modularization strategies, major equipment inquiry and budgetary pricing, and constructability assessments. This work identifies long-lead equipment, evaluates alternative designs, and establishes fabrication scope.

Quality FEED engineering reduces execution phase changes, enables accurate project budgeting and scheduling, and provides basis for contractor bidding. FEED investment—typically 1-3% of total project cost—delivers value through reduced execution risk and better project definition.
