Supplier prequalification · delivery evidence · collaboration governance
Prequalify a facade supplier through evidence that can survive project change
A long-term working relationship is not established by a past client name. It grows from verified capability, controlled products and samples, clear engineering interfaces, reliable delivery, traceability, change control, corrective action and periodic governance.
Five gates from candidate to governed supplier
Define scope
Product/system, project zones, quantities, programme, interfaces, evidence and decision authority.
Verify capability
Legal/manufacturing scope, current facility/process, capacity plan, quality system and relevant experience.
Approve solution
Exact product, samples, mock-up, drawings, system interfaces, tests and deviations.
Release delivery
Production plan, inspections, traceable lots, packaging, sequence, logistics and site acceptance.
Govern performance
Changes, nonconformance, corrective action, support, replacements, reviews and renewal decisions.
Facade supplier prequalification checklist
Capability and production scope
Confirm the legal/manufacturing entity, facility and actual product/process scope for the proposed facade units. Review current equipment/process information, controlled capacity and lead-time plan, critical subcontractors, contingency arrangements and evidence from comparable complexity—without treating factory size or a client logo as proof.
Quality documents and product evidence
Request the quality plan, inspection/test plan, current product data, named reports/certificates, calibration and batch records, nonconformance route and document control. Check product, dimensions, finish, method, standard edition, result, validity and exclusions; a generic certificate does not qualify every product or complete wall.
Samples and appearance control
Approve identified product samples and the permitted colour/texture range under stated conditions. Define master/control samples, mock-up, batch blending, shade/pattern management, signed approvals and where references are stored. Website images and an earlier project are not acceptance samples.
Engineering and interface support
Set the boundary between product supplier, facade engineer, structural engineer, specialist contractor and other designers. Require controlled drawings/data for product engagement, subframe, anchors, substrate, movement, water, cavity/fire interfaces, edges/corners, installation tolerances and replacement. Assign who calculates, tests, reviews and approves each interface.
Production, inspection and traceability
Connect approved product and samples to purchase order, production release, raw-material/batch references, inspections, test records, packaging marks and final installed locations. Define hold/witness points, release authority, retained records and how mixed, held or rejected material is controlled.
Delivery and site coordination
Align quantity take-off, specials, sequence, packaging, container/truck plan, customs where relevant, unloading, storage, lifting/access, site inspection, damage/shortage response and spares. Validate delivery capacity against the actual programme rather than a general capacity statement.
Change control
Require advance notification and authorized review for changes to item, dimensions, body, finish, sample range, process, plant, equipment, raw material, critical supplier, testing, packaging, lead time or documents. Define whether re-sampling, re-testing, mock-up or engineering review is required before release.
After-sales and corrective action
Set response routes for technical queries, delivery issues, nonconformance, root-cause review, corrective/preventive action, sorting, repair or replacement and warranty administration. Keep approvals and replacement references so a later unit is not selected from memory alone.
Commercial and contractual alignment
Compare the same product/system scope, tests/mock-ups, tooling/specials, packaging, freight, taxes/duties, site services, warranties, exclusions, intellectual-property/data needs and change mechanisms. Lowest unit price does not establish equivalent delivered scope or risk.
Governance and periodic review
Name accountable contacts, escalation paths, meeting/report cadence, confidentiality/data rules, audit rights and the buyer’s applicable conduct/compliance requirements. Review delivery, quality, change and support records against agreed measures; define who can suspend, reinstate, renew or end approved status.
| Area | Evidence to review | Decision boundary |
|---|---|---|
| Organization/capability | Current entity/facility scope, responsible team, production plan, relevant references and contingency | Capability must match the proposed product, volume, complexity, location and programme |
| Product/quality | Controlled product data, quality/inspection plan, reports, certificates, samples and traceability | Evidence applies only within its stated product, method, configuration, edition, result and validity |
| Engineering | Interface matrix, drawings, calculations/test route, deviations, mock-up and approvals | Supplier data does not replace the project professionals’ assigned design/approval duties |
| Delivery | Quantity/sequence, packaging, logistics, inspection, damage/shortage and spares plan | Release one project/batch only after its required records and approvals are complete |
| Ongoing relationship | Change notices, nonconformance/CAPA, support records, review measures and renewal status | Past approved status or client history is not permanent or universal approval |
What the October 2016 article actually recorded
The following items are transcribed from the old LOPO article. They are not independently proven by a Vanke document in the source set and are not evidence of a current relationship.
- Vanke dates
- The article stated that Vanke was established in 1984 and entered real estate in 1988. It also called Vanke the world’s largest professional residential developer and a leading company; those rankings were undefined and are not repeated as fact.
- LOPO date and scope
- The article stated that LOPO was established in 2002 and listed terracotta facade products, louvers/baguettes, wall tiles, brick pavers and cultured stone. This is a dated product-scope statement, not confirmation of today’s range or capacity.
- Relationship statement
- As of its 27 October 2016 publication, the LOPO-authored page described LOPO as Vanke’s “long-term cooperator” and curtain-wall supplier after passing a strict supplier test. The record includes no Vanke-authored confirmation, agreement, term or current status.
- 11 / 100+
- The page said Vanke requirements covered more than 100 indices under 11 aspects, including supplier aptitude, material standards and product quality. It did not name the checklist, revision, values, test methods or approval record, so these numbers are historical claims—not criteria to copy.
- Projects and quantities
- No project name, location, contract number, purchase order, product schedule, quantity, value, delivery date or installed result was supplied.
- Future/environment
- The article predicted more cooperation and linked both parties to green/environmental aims. A prediction is not subsequent evidence, and no environmental document supported the product claims.
Do not turn history into approval evidence
- Do not imply a current Vanke relationship, approval, endorsement, project award or purchasing commitment without current authorized documentation.
- Do not copy the “11 aspects / 100+ indices” claim into a project checklist as though its criteria are known.
- Do not qualify a supplier from brand reputation, client names, factory photographs or generic certificates alone.
- Do not transfer approval between products, plants, finishes, systems, projects, regions or time periods without the buyer’s accepted basis.
- Do not describe collaboration as long-term until scope, performance, change, support and governance records demonstrate it under the applicable agreement.
