FIM versus EPC - decision sheet
A generic project-delivery aid by Tech Made Easy
Choose FIM when
Direct control or early release creates more value than the interfaces the owner must absorb.
Choose EPC supply when
Single-point integration, logistics and performance accountability are worth the contractor's premium.
Do not decide on price alone
Compare the whole delivery system: capability, custody, interfaces, delay exposure and warranty response.
Five questions before the package decision
| Decision | FIM is stronger when | EPC supply is stronger when | Question that must be answered |
|---|---|---|---|
| Commercial leverage | Owner can aggregate demand or negotiate directly. | Contractor can price and manage the complete supply chain. | Is the apparent saving still real after owner-side management and interface cost? |
| Technical control | Owner needs direct influence over specification or supplier. | Performance responsibility should remain with one delivery party. | Who owns design integration and fitness for the complete system? |
| Schedule | Long-lead release must start before the EPC package is ready. | One contractor can sequence procurement with construction. | Who carries late delivery, resequencing, storage and remobilisation exposure? |
| Logistics and custody | Owner has the capability to manage transport and handover. | The contractor is better placed to manage door-to-workfront delivery. | Where do risk, title, inspection and care of materials transfer? |
| Warranty | Supplier warranty can be administered without creating a gap. | A single point of responsibility is worth the embedded premium. | Who responds when equipment, installation and system performance overlap? |
Minimum interface controls
| Interface | Typical FIM starting point | Typical EPC starting point | Evidence required |
|---|---|---|---|
| Specification and interface data | Owner / supplier | EPC | Approved interface register |
| Manufacture and factory quality | Owner / supplier | EPC | Inspection and test plan |
| Transport to named handover point | Define explicitly | EPC | Incoterm, route and delivery plan |
| Receipt, storage and preservation | Usually EPC after handover | EPC | Signed custody and preservation record |
| Installation and integration | EPC | EPC | Method statement and design interface |
| Defects and system performance | Split risk - close the gap | EPC | Back-to-back warranty and test matrix |

Professional-judgment note: This sheet is a generic decision aid, not legal, procurement or project-specific advice. “Typical” allocations are only a starting point. The executed contracts, technical schedules, Incoterms, insurance, warranty structure and responsibility matrix control the actual allocation.
