An EPC contractor decision is a 3-to-5-year commitment worth $50 million to $5 billion. It locks in the project's safety culture, schedule discipline, cost control, digital capabilities, subcontractor depth, and post-handover support — across the most expensive years of any greenfield investment. Yet most EPC evaluations still happen on a spreadsheet with 8 to 12 criteria, weighted toward price, scored by procurement teams who never have to live with the result. The 60-criteria checklist below covers the six dimensions that actually predict EPC delivery performance: Safety, Engineering, Procurement, Construction Execution, Digital Capability, and Commercial & Risk. Each criterion has a scoring weight and a red-flag indicator. The checklist filters bidders before the technical evaluation begins — turning EPC selection from a price contest into a structured capability match. Book an EPC evaluation consultation to apply the 60-criteria scorecard to your shortlist before you commit.
Safety is treated as a disqualifier dimension before any other evaluation occurs. A contractor with poor safety performance brings every other capability gap with them — schedule delays from incidents, regulatory shutdowns, insurance refusals, and a culture that treats compliance as adversarial. Below the safety threshold, no other score matters.
13-year TRIR (Total Recordable Incident Rate) — industry benchmark or better
2EMR (Experience Modification Rate) ≤ 1.0 confirmed by insurer
3OSHA citations history — none open, none repeated, no willful violations
4Documented HSE management system aligned to ISO 45001 / OHSAS 18001
5Dedicated full-time safety lead on projects of comparable size
6Subcontractor safety prequalification process documented and audited
7Behaviour-based safety program with leading indicator reporting
8Process safety management for hazardous chemical / energy environments
10Worker training, certifications, and badging system traceable to individual
Red Flag
Any TRIR above industry benchmark, EMR above 1.0, repeated OSHA citations, or unwillingness to share 3-year incident history disqualifies the bidder from further evaluation — regardless of engineering or commercial scores.
Engineering capability is the source of every downstream cost. A weak FEED produces ambiguous specifications that detonate at construction. Strong front-end planning is the single most-cited qualifier for midstream and process project EPC contractors — and the same principle holds for greenfield manufacturing.
11FEED-quality engineering team with named lead engineers for each discipline
13Project references in your industry sector at comparable scale (±30%)
14Integrated specification owner role — single accountable engineering owner
15Document control system with version management and revision tracking
16Code compliance: ASME, API, NFPA, IEEE, ISA — applicable to your project
173D model and clash detection during engineering — BIM Level 2 minimum
18Constructability review process built into engineering deliverables
19Sustainability & ESG design capability — net-zero, water reuse, energy recovery
20Operability and maintainability input from operations engineers
Red Flag
No named lead engineers, no in-house disciplines (everything subcontracted), no integrated specification owner, or zero comparable industry references — engineering will fail at construction.

Long-lead procurement runs the critical path of nearly every greenfield project. An EPC with weak vendor relationships, poor escalation discipline, or no parallel-procurement experience will deliver schedule slip and cost variation regardless of how strong the engineering is.
21Documented long-lead procurement methodology with parallel-FEED release
22Vendor master with 3+ qualified suppliers per major equipment category
24Escalation clauses, currency hedging, and price-lock mechanisms in POs
25Expediting team with named expediters per major PO
26Factory Acceptance Test (FAT) protocols for all major equipment
27Inland and international logistics capability including customs and tariffs
28Spare parts strategy with critical-spares list developed during procurement
29Tariff exposure analysis and Foreign Trade Zone strategy where relevant
30Subcontractor sourcing capability across mechanical, electrical, civil, controls
Red Flag
Single-source vendor relationships for major equipment, no escalation discipline, or unwillingness to release long-lead items at 70% FEED — these compound into a schedule failure during construction.
Dimension 4 — Construction Execution (10 criteria, 20% weight)
Construction execution is where engineering and procurement decisions meet reality. EPC subcontractor prequalification involves formal review of crew capabilities, insurance coverage, safety records, and mobilization capacity. Strong EPCs run this discipline; weak EPCs subcontract reflexively without prequalification — and the project absorbs the consequences.
31Master schedule with dependency mapping, critical path identification
32Schedule of values tied to milestones and completion-based payments
33Self-perform capability for critical scopes vs. complete subcontracting
34Subcontractor prequalification process — capability, insurance, bonding
35Crew availability for mobilization within project schedule windows
36Site management with named site manager and reporting structure
37Quality control inspection plan with hold points and ITPs
39Change order discipline with documented impact analysis and approval
40Punch list and turnover process with operations sign-off requirements
Apply the 60-Criteria Scorecard to Your EPC Shortlist Before You Commit
iFactory's EPC evaluation consultation runs your shortlisted EPC contractors through the full 60-criteria scorecard across safety, engineering, procurement, construction, digital capability, and commercial risk dimensions — with weighted scoring, red-flag identification, and side-by-side comparison delivered before contract negotiation.
Dimension 5 — Digital Capability (10 criteria, 10% weight)
Digital capability is the dimension that separates a 2026 EPC from a 2010 EPC. BIM-driven clash detection, digital twin construction monitoring, drone and laser scanning progress verification, and AI-native plant architecture are no longer differentiators — they are the table stakes for delivering an AI-ready manufacturing facility. EPCs without these capabilities deliver plants that need expensive digital retrofits within their first 2 years.
41BIM Level 2+ with clash detection across all design disciplines
42Digital twin construction monitoring — 3D model vs. as-built comparison
43Drone and laser scanning for progress verification and survey accuracy
44Common Data Environment (CDE) for documents shared with client and trades
45Virtual commissioning capability for PLC code and controls integration
46CMMS and MES architecture experience for handover-ready data structure
47Sensor and instrumentation schedule designed for AI-native operations
48OT cybersecurity by design — IEC 62443 architecture experience
49Private 5G / Wi-Fi 6E network design capability for production environments
50Edge compute and AI infrastructure provisioning in plant design
Red Flag
EPCs that score below 6/10 here will deliver a 2010-era plant that needs 4 to 6× retrofit cost to become AI-ready. The greenfield window for this is now — not at year 3.
The commercial dimension is what protects the project when execution does not go to plan — and it always doesn't go to plan in some way. Bonding capacity, insurance coverage, financial health, contract structure, and dispute resolution discipline are what separate a contractor who will honour their obligations under stress from one who will litigate the variation orders into year five.
51Performance bonding capacity at full project value confirmed by surety
52Insurance coverage — general liability, professional, builder's risk, umbrella
53Audited financial statements showing 3-year stability and project capacity
54Lump-sum / GMP / reimbursable contract experience matching your structure
55Performance guarantees — capacity, quality, OEE, energy intensity at handover
56Liquidated damages and bonus / penalty schedule alignment to milestones
57Change order pricing transparency with documented markup methodology
58Dispute resolution clause — mediation, arbitration, litigation history
59Warranty period and post-handover service commitment specified
60Reference checks — minimum 5 owner references on comparable projects
Scoring Methodology: Turning the Checklist Into a Decision
Scoring is what converts the 60 criteria into a defensible award decision. Each criterion is scored on a 1 to 10 scale within its dimension. Dimensions are weighted, with Safety acting as both a weighted dimension and a pre-qualifier disqualifier. Total scores rank bidders objectively while the red flags ensure no contractor advances on price despite a capability gap.
1
Pre-Qualify on Safety
Apply Dimension 1 criteria as a pass/fail gate. Below threshold = removed from evaluation regardless of other capabilities. No bidder advances on price if safety is unsatisfactory.
2
Score Each Dimension 1–10
Each criterion scored 1 to 10 with documented evidence. Dimension score = average of the 10 criterion scores. Use structured interviews with engineering, procurement, safety, and operations.
Any red flag triggers a discussion: address gap, negotiate mitigation, or remove from shortlist. Final selection combines weighted score, red-flag mitigation, and commercial terms — not price alone.
Expert Perspective: Why Price-Driven EPC Selection Costs the Most Over the Project Life
The EPC selections we review at 12 months into execution follow a predictable pattern. The projects where price dominated the bid evaluation are dealing with safety incidents, schedule slip, change order disputes, or all three. The projects where a structured scorecard ran the evaluation are still on plan — sometimes paying 5 to 12% more on the original contract, but spending 30 to 50% less on change orders, dispute resolution, and rework. The difference is not contractor quality in the abstract. Every reputable EPC has done excellent projects and disastrous ones. The difference is whether the evaluation matched your specific project's capability requirements to the contractor's actual capability profile across all six dimensions — not just the two or three the procurement spreadsheet measured. The 60-criteria scorecard is not exotic. Every criterion in it is something a serious owner should know about their EPC before commitment. What is exotic is actually running the discipline before contract award rather than discovering the gaps during construction.

Don't Find Out About EPC Capability Gaps During Construction
iFactory's EPC evaluation consultation applies the 60-criteria scorecard across all six dimensions (Safety, Engineering, Procurement, Construction Execution, Digital Capability, Commercial & Risk), produces side-by-side weighted comparisons of your shortlisted EPCs, identifies red flags before they become construction surprises, and delivers a defensible award recommendation with documented evidence per criterion — all before contract negotiation begins.
Shorter checklists feel more practical but consistently miss the capability gaps that drive EPC failure. The 8 to 12 criteria most procurement teams use cover price, safety summary, and a high-level capability statement — leaving 80% of the real risk surface unevaluated. The 60-criteria framework covers six capability dimensions (Safety, Engineering, Procurement, Construction Execution, Digital Capability, Commercial & Risk) with 10 specific criteria each. Each criterion is something a serious owner needs to know before committing 3 to 5 years and $50 million to $5 billion to a contractor. Running 60 criteria takes 2 to 4 weeks of disciplined evaluation per bidder — meaningfully more effort than a typical procurement scorecard, but small compared to the cost of discovering capability gaps during construction.
Is Safety really worth a 25% weight, and what does "disqualifier" mean in this context?
Safety carries a 25% explicit weight in the scoring methodology, but functions as a pre-qualifier disqualifier in practice. A contractor with poor safety performance carries other capability gaps with them: schedule slip from incidents, regulatory action that halts work, insurance refusals that delay mobilization, and a workplace culture that treats compliance as adversarial. The "disqualifier" treatment means a bidder below the safety threshold is removed from evaluation entirely — not weighted-averaged into the total. This protects the owner from the false economy of accepting a low-price bid from a contractor whose safety performance will compound into cost overruns through other dimensions. EPC contractor qualifications for industrial projects consistently include high safety ratings as a foundational requirement — this scorecard simply formalizes that practice.
How do I evaluate digital capability when most EPCs claim BIM and digital twin?
Claims and capability differ substantially. The 10 digital criteria in Dimension 5 are designed to surface the difference. Ask for actual deliverables from prior projects: BIM federated models with clash detection logs, digital twin construction monitoring outputs showing model vs. as-built comparison, drone and laser scan reports with deviation analysis, Common Data Environment screenshots showing real document workflow, virtual commissioning PLC code validation evidence, and CMMS architecture handover documents. EPCs that have actually deployed these capabilities can produce the artifacts within a week. EPCs claiming capability without genuine deployment cannot — they will offer marketing decks instead of project evidence. The differentiator is not the claim, it is the artifact.
Can the 60-criteria framework be adapted to lump-sum, GMP, or reimbursable contract structures?
Yes, with weighting adjustments. The 60 criteria themselves are contract-structure-neutral — they evaluate underlying contractor capability, not commercial terms. The dimension weights shift modestly across structures: lump-sum projects benefit from heavier Engineering weight (mistakes lock in pricing); GMP structures benefit from heavier Procurement and Construction weight (the contractor's discipline drives savings or overruns); reimbursable structures benefit from heavier Commercial weight (transparency and change order discipline are the primary risk surfaces). Criterion 54 explicitly checks that the EPC has experience with your specific contract structure. The scoring methodology and red-flag discipline remain identical across structures.
