| Safety Design and Compliance | 25% | Review design risk assessments, impact protection, fall zones, access control, emergency exits, fire-safety coordination, and inspection procedures. | The proposal identifies applicable local building, fire, electrical, and amusement-safety requirements and provides documented testing or inspection records for critical components. | Vague safety statements, no risk assessment, insufficient padding details, or a design that ignores local fire and occupancy requirements. | __/5 |
| Relevant Project Experience | 15% | Ask for completed indoor recreation projects with similar floor area, ceiling height, visitor capacity, age groups, and activity mix. | At least three verifiable projects with photographs, layout drawings, operating references, and information about project scope and completion date. | Only concept images are provided, references cannot be contacted, or previous projects are unrelated to trampoline parks. | __/5 |
| Design Capability and Space Planning | 12% | Evaluate traffic flow, sightlines, spectator areas, reception, lockers, party rooms, staff zones, maintenance access, and evacuation routes. | The layout separates active and non-active areas, supports efficient supervision, minimizes congestion, and includes accurate dimensions and equipment clearances. | Poor circulation, blind spots, unrealistic capacity assumptions, or layouts that leave no practical maintenance access. | __/5 |
| Product Quality and Materials | 12% | Check steel specifications, welding quality, foam density, pad thickness, trampoline fabric, netting, fasteners, flooring, and replacement-part availability. | Materials have clear specifications, suitable wear resistance, consistent finishing quality, and a documented replacement schedule for high-wear parts. | Unspecified materials, inconsistent dimensions, low-density padding, exposed edges, corrosion-prone parts, or no spare-parts plan. | __/5 |
| Customization and Engineering Support | 10% | Determine whether the manufacturer can adapt designs to irregular buildings, columns, low ceilings, structural constraints, and local operating requirements. | The supplier provides measured drawings, load information, installation details, revisions, and coordinated engineering documentation before production. | Fixed templates only, limited drawing revisions, no structural coordination, or unclear responsibility for site measurements. | __/5 |
| Manufacturing Quality Control | 8% | Review material receiving checks, welding inspections, dimensional checks, assembly trials, packaging controls, and final inspection records. | A documented quality-control process exists, with inspection checkpoints, traceable specifications, corrective-action records, and pre-shipment verification. | Quality depends only on visual inspection, no inspection checklist, inconsistent samples, or refusal to share quality procedures. | __/5 |
| Installation and Project Management | 7% | Confirm site survey procedures, installation crew qualifications, schedule control, coordination with contractors, commissioning, and handover documents. | The contract defines installation scope, milestones, site responsibilities, acceptance criteria, training, and procedures for correcting installation defects. | Unclear installation responsibility, no commissioning process, unrealistic lead times, or incomplete handover documentation. | __/5 |
| Warranty and After-Sales Service | 6% | Compare warranty coverage, response times, technical support, maintenance instructions, spare-parts pricing, and remote troubleshooting capability. | Warranty terms are written clearly, exclusions are defined, replacement parts are available, and service response times are stated in the agreement. | Verbal promises only, unclear warranty exclusions, no maintenance manuals, or difficult access to commonly replaced parts. | __/5 |
| Commercial Transparency | 5% | Compare the quotation structure, inclusions, exclusions, taxes, packaging, shipping, installation, certification, payment terms, and change-order costs. | The quotation is itemized and allows fair comparison between suppliers without hidden costs or ambiguous technical descriptions. | An unusually low price with major exclusions, unclear quantities, inconsistent specifications, or pressure for a large non-refundable payment. | __/5 |
