Legal Business Status |
Confirm that the supplier is legally registered and authorized to trade construction materials in the relevant jurisdiction. |
Business registration record, tax registration, registered address, and authorized representative details. |
The legal name and registration details should match across official records, quotations, contracts, and invoices. |

| 2 |
Product Standards and Compliance |
Specify the required technical standard before requesting quotations and confirm that supplied materials meet it. |
Product data sheets, declarations of performance or conformity, applicable test reports, and standards references. |
The standard edition, product grade, dimensions, and intended application must match the project specification. |
High |
| 3 |
Quality Management System |
Assess whether the supplier uses documented quality-control procedures for purchasing, production, inspection, and corrective action. |
Quality manual, inspection and test plan, calibration records, internal audit results, and a current management-system certificate where applicable. |
Quality controls should be documented, assigned to responsible personnel, and supported by traceable inspection records. |
Medium |
| 4 |
Material Traceability |
Require batch, heat, lot, or serial identification so delivered materials can be traced back to their source and test results. |
Certificates of origin, mill or batch certificates, production dates, lot numbers, delivery records, and chain-of-custody documents. |
Each delivery should be clearly linked to its purchase order, inspection record, and applicable test certificate. |
High |
| 5 |
Independent Testing |
Use a competent independent laboratory for critical materials or when supplier documentation cannot be independently confirmed. |
Laboratory accreditation details, signed test reports, sampling method, test date, specimen identification, and measured results. |
Testing should use recognized methods and the results should satisfy the acceptance criteria stated in the project documents. |
High |
| 6 |
Past Project Performance |
Request relevant references from projects with similar material specifications, quantities, delivery conditions, and quality requirements. |
Client references, completed-project records, nonconformance history, delivery performance data, and documented corrective actions. |
References should be recent enough to reflect the supplier’s current facilities, processes, and management team. |
Medium |
| 7 |
Production Capacity |
Check whether the supplier can meet the required volume, production schedule, packaging requirements, and delivery sequence. |
Capacity statement, production schedule, equipment list, workforce information, inventory records, and contingency plan. |
Planned output should cover the project demand without relying on unverified subcontracting or unrealistic lead times. |
High |
| 8 |
Financial and Commercial Stability |
Evaluate the supplier’s ability to remain operational throughout the contract and clearly define payment and price-adjustment terms. |
Trade references, credit information, insurance certificates, warranty terms, quotation validity, and documented change-order procedures. |
The contract should identify currency, taxes, delivery terms, payment milestones, warranty period, and responsibility for defects. |
Medium |
| 9 |
Health, Safety, and Environmental Controls |
Verify that the supplier manages worker safety, hazardous substances, waste, emissions, and environmentally sensitive materials responsibly. |
Safety policy, risk assessments, safety training records, material safety data sheets, environmental permits, and incident statistics. |
Required permits and safety documentation should be current, relevant to the supplied material, and available before delivery. |
High |
| 10 |
Pre-Delivery Inspection and Acceptance |
Create a documented inspection process covering quantity, dimensions, visible defects, packaging, labeling, storage, and acceptance criteria. |
Approved samples, inspection checklists, photographs, delivery notes, nonconformance reports, and signed acceptance records. |
Do not release materials for installation until inspection results and required certificates have been reviewed and accepted. |
