| Relevant project experience | A portfolio of completed auditoriums, cinemas, performing arts venues, or other comparable installations. | Examples show seating layouts and project requirements similar to yours, such as fixed rows, aisle access, or retractable seating. | Confirm the manufacturer’s role, project scope, and whether the examples are comparable in size and use. |
| Production capacity | An outline of production stages, available equipment, workforce planning, and capacity for the requested quantity. | The supplier explains how orders are scheduled and how production progress and quality are monitored. | Check whether the stated lead time accounts for approvals, materials, production, packing, and shipping. |
| Customization capability | Drawings or specifications covering dimensions, upholstery, finishes, accessories, and layout options. | The manufacturer can document which features are standard, optional, or custom and explain how changes affect cost and schedule. | Ask how proposed designs will be checked against room dimensions, sightlines, aisles, and applicable project requirements. |
| Quality control | A description of incoming-material checks, in-process inspections, final inspection, and defect handling. | Inspection steps and acceptance criteria are recorded and can be shared before an order is placed. | Clarify how nonconforming products are corrected and who approves any changes to agreed specifications. |
| Materials and durability | Material specifications, care instructions, warranty terms, and relevant test reports where available. | The supplier identifies the materials used in key components and provides clear guidance on maintenance and replacement parts. | Verify that any fire, safety, or performance claims apply to the exact material and product configuration offered. |
| Installation and logistics | Packing details, delivery schedule, installation responsibilities, and site-readiness requirements. | Responsibilities for transport, unloading, installation, and handover are clearly assigned in writing. | Confirm access routes, storage needs, installation sequence, and how delays or damaged goods will be handled. |
| After-sales support | Written warranty conditions, service contact process, spare-parts availability, and response procedures. | Support coverage, exclusions, claim steps, and availability of common replacement parts are explained before purchase. | Check warranty duration and coverage in the contract; ask whether service or parts costs are included or charged separately. |
