| 1 | International Project Experience | Number of completed installations, operating years, project locations, and parking spaces delivered | Prefer suppliers with documented installations in multiple countries and references for projects of similar size and climate | Project list, completion certificates, customer references, site photographs, and commissioning records |
| 2 | Parking Capacity and Layout Flexibility | Maximum spaces per system, vehicle dimensions, floor height, footprint, and expansion capability | The proposed configuration should match local vehicle sizes, building constraints, traffic flow, and future expansion needs | General arrangement drawings, structural loads, equipment dimensions, vehicle envelope data, and capacity calculations |
| 3 | Throughput and Retrieval Performance | Average retrieval time, peak-hour throughput, simultaneous vehicle handling, and queue capacity | Evaluate performance using a defined traffic model rather than relying on a single advertised retrieval time | Factory acceptance test, simulation results, peak-period calculations, and witnessed site performance test |
| 4 | Safety and Regulatory Compliance | Safety sensors, emergency stops, interlocks, fire protection coordination, risk assessment, and applicable certifications | The system should comply with applicable local building, fire, machinery, electrical, accessibility, and occupational-safety requirements | Risk assessment, conformity documentation, inspection reports, electrical schematics, safety test records, and local approvals |
| 5 | Reliability and Availability | System uptime, mean time between failures, fault frequency, recovery time, and preventive-maintenance interval | Request site-specific availability targets and distinguish equipment uptime from complete operational availability | Anonymized operating data, maintenance logs, failure history, spare-parts records, and service-level agreement |
| 6 | Vehicle Compatibility | Maximum vehicle length, width, height, weight, wheelbase, ground clearance, and tire dimensions | The loading platform should safely accommodate the target vehicle population, including SUVs and approved electric vehicles where relevant | Published vehicle envelope, weight limits, platform drawings, acceptance-test checklist, and customer operating rules |
| 7 | Automation and Software Integration | License-plate recognition, access control, payment integration, mobile access, API availability, and data reporting | Use open and documented interfaces where possible; confirm compatibility with the existing parking-management system | API documentation, cybersecurity policy, integration test, data-flow diagram, user-permission matrix, and service documentation |
| 8 | Installation and Commissioning Capability | Design support, civil-work coordination, installation duration, testing stages, training, and handover process | Require a clearly defined responsibility matrix covering supplier, contractor, electrical works, structural works, and authorities | Project schedule, method statement, interface matrix, commissioning plan, training records, and handover documentation |
| 9 | After-Sales Service and Spare Parts | Technical-support hours, remote diagnostics, local technicians, response time, spare-parts lead time, and training coverage | Select a supplier that can provide long-term support in the installation country and define response times contractually | Service-level agreement, regional support contacts, spare-parts inventory plan, escalation process, and maintenance contract |
| 10 | Total Cost of Ownership | Equipment price, civil works, installation, energy use, software fees, maintenance, insurance, replacement parts, and end-of-life costs | Compare a full-life-cost model over the planned operating period instead of comparing equipment price alone | Itemized quotation, operating-cost assumptions, maintenance schedule, warranty terms, energy estimate, and lifecycle-cost worksheet |
