• I.10 — Materials and logistics: Expedite critical spools, valves, catalysts, refractory, and long-leads; manage laydown, preservation, and receiving QC.
• I.11 — Lifting and rigging control: Approve lift plans (ordinary/critical), crane schedules, exclusion zones, and rigging inspections.
• I.12 — Turnaround readiness and execution (if TAR/STO): Own event sequence, critical path discipline, discovery work screening, and daily de-bottlenecking.
• I.13 — Pre-commissioning and handover: Oversee flushing, leak tests, reinstatement, loop checks, and turnover dossier completion to commissioning/operations.
• I.14 — Reporting and governance: Issue daily/weekly status, look-aheads, KPIs (CPI, SPI, TRIR), and risk/opportunities to the Project Manager.
• I.15 — Lessons learned and closeout: Capture execution learnings, as-built redlines, and final quantities for benchmarking and future estimates.
