| 1 | Confirm the required fire-resistance rating | Door, frame, glazing, hardware, and seals should match the required rating, such as 30, 60, 90, or 120 minutes. | Project specification, test report, classification report, and product data sheet identifying the complete door-set configuration. | 20% | 9 | 7 | 9 |
| 2 | Check certification and test-standard compliance | Verify that testing is relevant to the target market and covers the complete assembly rather than the door leaf only. | Independent test documentation referencing applicable standards such as EN 1634-1, UL 10C, NFPA 80, or the project-specified equivalent. | 20% | 9 | 6 | 8 |
| 3 | Compare the quotation scope line by line | Identify whether the price includes the frame, hinges, closer, lockset, smoke seals, glazing, delivery, installation, and taxes. | Itemized quotation with quantities, specifications, unit prices, exclusions, optional items, currency, tax treatment, and validity period. | 15% | 8 | 8 | 7 |
| 4 | Evaluate supplier quality-control reliability | Assess traceability, incoming-material checks, production inspections, final inspection, and corrective-action procedures. | Quality-management certificate where applicable, inspection checklist, batch traceability method, nonconformance process, and sample inspection records. | 15% | 8 | 7 | 9 |
| 5 | Verify production capacity and lead time | Confirm that the quoted schedule covers approval, manufacturing, testing, packing, shipping, and installation coordination. | Written production schedule, stated monthly capacity, confirmed delivery milestones, shipping terms, and escalation procedure for delays. | 10% | 9 | 8 | 7 |
| 6 | Assess warranty and after-sales support | Review warranty duration, covered components, response time, spare-parts availability, and responsibility for installation defects. | Signed warranty terms, service-level commitment, maintenance instructions, spare-parts list, and documented claims process. | 10% | 8 | 6 | 8 |
| 7 | Use total cost of ownership instead of price alone | Compare purchase price together with installation, transport, maintenance, replacement parts, compliance risk, and potential delay costs. | Five-year cost estimate, delivery and installation breakdown, maintenance requirements, payment terms, and clearly stated commercial assumptions. | 10% | 8 | 9 | 7 |
| Weighted Reliability and Quotation Evaluation Result | 100% | 8.55 / 10 | 7.15 / 10 | 8.05 / 10 |
| Recommended selection approach | Select the highest-scoring quotation only after confirming that its certificates, scope, lead time, installation method, and warranty terms satisfy the project specification. |
