- I.X — Assure compliance: PSM/MoC, MOC packages, API/ASME/NFPA/IEC/OSHA adherence, environmental permit conditions, and corporate technical standards.
- I.XI — Stakeholder management: align operations, maintenance, inspection/integrity, HSE, turnaround, supply chain, finance, and document control.
- I.XII — Reporting and governance: weekly/monthly KPIs (CPI, SPI), risk/opportunity log, decision registers, and stage-gate approvals.

- II.III.3 — Travel for vendor FATs, fabrication yard inspections, and inter-site coordination.
Key project control formulas (used routinely)
- II.IV.1 — Earned Value: EV, Planned Value: PV, Actual Cost: AC
- II.IV.2 — Cost Performance Index: CPI = EV / AC
- II.IV.3 — Schedule Performance Index: SPI = EV / PV
- II.IV.4 — Estimate at Completion (typical): EAC = BAC / CPI
- II.IV.5 — Estimate to Complete: ETC = EAC - AC
- II.IV.6 — Contingency drawdown curves aligned to risk burn-down; Monte Carlo for P50/P80 cost/schedule (estimated if not mandated).
