EPC Project Planning & Control - Overview and Importance

A: A: Float hides the slip on paper, but downstream curves steepen. Indirects go up. That's the trap. B: Schedules don't self-heal; re-sequencing needs an owner and an MOC. C: Early civils and structural steel feel it first, not commissioning. D: LDs only trigger once contractual milestones are breached, not when float erodes.

A: A: Service text matching isn't control of change. That's how wrong valves get installed. B: This freezes the error before steel and piping lock it in. C: GA drawings often lag P&IDs in brownfields. Tag authority is defined, not assumed. D: By commissioning it's too late; rework risk is baked in.

A: A: Time can absorb predictable weather hits if modeled. B: A code failure forces redesign and possible re-procurement; float won't save you. C: That's exactly what schedule contingency masks. D: Minor inefficiencies get lost inside float without drama.

A: A: Blind fast-tracking multiplies rework once piping and layouts shift. B: Civils and steel can tolerate early release with frozen loads and footprints. C: Schedule hit is unjustified at 60% with orders placed. D: EPCM changes the contract model, not a mid-project planning lever.
