Two delivery models. One keeps you in control of your project. The other hands the keys to a contractor. Here's how they compare and how to decide which one fits your next capital project.
Under EPC (Engineering, Procurement and Construction), you hire a single contractor who designs, buys, and builds everything. They hold all the subcontracts. You pay a lump sum and get a finished facility. Simple but you give up visibility and control.
Under EPCM (Engineering, Procurement and Construction Management), every contract stays in your name. The EPCM firm manages the project on your behalf (engineering, procurement coordination, construction supervision) but you sign the contracts, you approve the suppliers, and you see every cost line. You keep control.
| Aspect | ⚠️ EPC — Turnkey | ✅ EPCM — Owner's Model |
|---|---|---|
| 📄 Contracts | Held by contractor — no direct relationship with subcontractors | Held by you — every supplier in your name |
| 💶 Cost visibility | Lump sum — margin hidden, line items unavailable | Full open-book — every cost line visible |
| 🏭 Supplier selection | Contractor decides — own preferred supply chain | You decide — your qualification requirements respected |
| 🔄 Scope changes | Variation orders — typically +15–25% markup | Managed at actual cost — no markup |
| 📊 Reporting | Monthly — you learn about problems after the fact | Weekly open reporting — you see what we see |
| ⚖️ Risk | Contractor carries it — priced into the lump sum | Shared — managed transparently with early escalation |
| 🧾 Fee model | % of total spend — incentive to increase project cost | Time-based — efficient delivery benefits everyone |
Choose EPCM when your project involves regulatory compliance (cGMP, HACCP, EU GMP), when you need to select specific suppliers for qualification reasons, when you want full visibility over costs, or when you're operating in a live production environment where coordination matters more than speed.
Choose EPC when the scope is completely defined upfront, when speed matters more than control, or when you genuinely want a single point of accountability and are willing to pay the premium for it.
Most food and pharmaceutical projects are better suited to EPCM because the regulatory environment demands traceability, the qualification lifecycle requires client involvement, and the cost of getting it wrong is measured in failed inspections and delayed production.
Under the C2 Method, we sit on your side of the table throughout the entire project. We manage your engineering, coordinate your procurement, and supervise your construction but every contract stays in your name. You keep control. We keep things on track.
Takes 2 minutes. Based on your project budget, regulatory environment, and contractor complexity. No generic answer — specific to your situation.
