| Manufacturing Quality System | Assess whether production, inspection, corrective actions, and document control are managed consistently. | A current ISO 9001 certificate, certificate scope, issuing body, audit status, and sample quality-control records. | The certificate should cover the relevant design, fabrication, assembly, or trading activities rather than an unrelated business scope. | 15% |
| Structural Design and Materials | Review the frame, enclosure, roof, floor, lifting points, transport loads, wind exposure, and site-specific structural requirements. | Signed drawings, material specifications, weld procedures, load calculations, corrosion-protection details, and third-party test reports where required. | Engineering documents should identify material grades, design loads, connection methods, tolerances, and the applicable destination-country code. | 18% |
| Electrical and Life-Safety Compliance | Verify electrical protection, grounding, fire detection, emergency lighting, escape routes, and local approval requirements. | Wiring diagrams, protection-device specifications, insulation or dielectric test records, fire-system documentation, and applicable conformity reports. | Compliance must be assessed against the destination market; CE marking alone does not replace building, fire, or planning approval. | 18% |
| Thermal, Moisture, and Acoustic Performance | Compare insulation, condensation control, waterproofing, ventilation, heating and cooling, and occupant noise conditions. | Wall and roof build-ups, insulation data, HVAC specifications, waterproofing details, condensation calculations, and test results where available. | The proposed assembly should be matched to the destination climate zone and intended occupancy, not judged only by marketing claims. | 12% |
| Customization and Engineering Capability | Determine whether the supplier can adapt layouts, utilities, finishes, furniture, access systems, and regional requirements. | Approved drawings, revision history, bill of materials, engineering-change procedure, and a clearly defined design-freeze process. | A capable supplier should provide coordinated architectural, structural, mechanical, and electrical drawings before production approval. | 10% |
| Factory Capacity and Production Control | Check whether the factory has adequate space, equipment, skilled labor, subcontractor control, and capacity for the required quantity. | A live or independent factory audit, production-flow map, equipment list, capacity statement, inspection plan, and shipment records with sensitive information removed. | Capacity claims should be supported by observable production resources and a schedule linked to agreed milestones. | 10% |
| Testing, Inspection, and Pre-Shipment Acceptance | Establish how dimensional accuracy, finishes, utilities, equipment operation, leakage, and packaging are checked before shipment. | Inspection and test plan, factory acceptance checklist, photographic records, nonconformance reports, and independent pre-shipment inspection results. | Payment and shipment should be linked to documented acceptance criteria agreed before manufacturing begins. | 10% |
| Export Packaging and Logistics | Review transport dimensions, lifting points, loading method, weather protection, customs documentation, and installation access. | Packing specifications, loading photographs, gross and net weights, package dimensions, lifting instructions, commercial invoice, packing list, and origin documents. | The logistics plan should be compatible with the selected Incoterm, port restrictions, local roads, cranes, and final-site access. | 7% |
| Installation and After-Sales Support | Clarify installation responsibility, spare parts, remote support, warranty exclusions, response times, and technician availability. | Installation manual, commissioning checklist, spare-parts list, warranty terms, service-level agreement, and anonymized project references. | The contract should define who handles site works, utility connections, defects, replacement parts, and warranty travel costs. | 10% |
