• Own the P& integration of the project across all disciplines to ensure design consistency.
• Prepare engineering documents (P&IDs, foundation loading charts, valves list, equipment data sheets, heat‑exchanger data sheet, paint and lining matrix, piping and valve specs) within specified deadlines.
• Prepare Material Purchase Specifications (MPS) and review and release technical bid evaluations (TBEs). After purchase orders, review and approve supplier submittals to ensure on‑schedule execution.
• Coordinate heavily with the 3‑D Plant Design Team to complete 3‑D plant design of new facilities without performing CADD work; deliver annotated construction drawings of high quality.
• Facilitate HAZOP and plant design reviews for new plants.
• Maintain detailed bill of materials (BOM) in the company ERP system (IFS) and issue purchase requisitions using the ERP system.
