| Applicable Safety Standard | Whether the complete elevator design is assessed against the code required in the destination market. | Use the locally applicable standard, such as EN 81-20 and EN 81-50, ISO 8100-1 and ISO 8100-2, ASME A17.1/CSA B44, or the applicable national standard. | Current design basis, type-examination documents where applicable, safety-component certificates, and a clause-by-clause compliance matrix. | 15% |
| Market Certification | Whether conformity documentation matches the installation country and the actual elevator configuration. | For the European Union, verify conformity under Directive 2014/33/EU and the required conformity-assessment route. Do not treat a general quality certificate as elevator conformity approval. | Declaration of Conformity, notified-body documentation where required, technical file index, certificates for safety components, and traceable product identification. | 10% |
| Capacity and Traffic Design | Rated load, passenger flow, building population, number of floors, travel height, and expected peak-period demand. | Common passenger-lift capacities are approximately 630–1,600 kg; final selection should be based on a traffic calculation rather than capacity alone. | Traffic-analysis report, rated-load calculation, number-of-elevators study, dispatching assumptions, and peak up-peak or lunch-peak results. | 10% |
| Speed and Travel Configuration | Rated speed, total travel, number of stops, acceleration, deceleration, and ride comfort. | Approximately 1.0–2.5 m/s is common for many low- and mid-rise projects; higher speeds may be appropriate for taller buildings when supported by a complete traffic and comfort study. | Speed profile, ride-quality test results, vibration measurements, travel-time calculation, and approved shaft and machine-room drawings. | 8% |
| Accessibility and Usability | Car dimensions, door clear opening, control-panel reach range, audible and visual indicators, and wheelchair or stretcher access. | Specify accessibility requirements using the destination code, such as EN 81-70 or ISO 21542, with a clear door opening commonly selected in the 800–1,100 mm range according to the building use. | Accessibility layout, door-opening measurement, control-panel height, tactile and Braille details, audio-announcement specification, and approved interior drawings. | 8% |
| Fire and Emergency Functions | Fire recall, emergency power interface, firefighter operation, alarm interfaces, emergency lighting, and two-way communication. | Apply the fire and emergency provisions required by the local building code; EN 81-72 may apply to firefighting lifts, while North American projects may require provisions from ASME A17.1/CSA B44 and the adopted building code. | Fire-strategy interface schedule, emergency-operation sequence, wiring diagrams, battery or emergency-lighting data, and witnessed functional-test records. | 8% |
| Energy Performance | Drive efficiency, standby consumption, lighting controls, regenerative options, and expected operating profile. | Request an energy classification or measured calculation using ISO 25745-2 where applicable; compare both running energy and standby energy under the same traffic assumptions. | ISO 25745-2 assessment or equivalent test data, standby-load schedule, annual energy model, drive efficiency data, and assumptions for daily trips. | 8% |
| Reliability and Availability | Failure frequency, controller and drive durability, environmental limits, spare-parts continuity, and service access. | Set a project-specific availability target, commonly at least 99% excluding planned maintenance, and require the calculation method to be stated clearly. | Reference-project performance data without confidential customer names, failure-mode analysis, preventive-maintenance schedule, environmental ratings, and availability calculation method. | 10% |
| Lifecycle Support | Local technicians, remote diagnostics, response time, spare-parts coverage, modernization capability, and training. | Prefer a documented regional service network, defined emergency-response targets, spare-parts availability for the expected service life, and a modernization path that does not require full replacement where avoidable. | Service-level agreement, technician coverage map, escalation procedure, spare-parts policy, training plan, remote-monitoring description, and sample maintenance reports. | 12% |
| Cybersecurity and Data Governance | Remote monitoring, network connections, user permissions, software updates, event logs, and protection of building data. | Require documented access control, encrypted communication where remote connectivity is used, vulnerability-management procedures, backup arrangements, and clear ownership of operational data. | Network architecture, cybersecurity policy, update process, access-control matrix, data-retention terms, incident-response procedure, and penetration-test summary where available. | 5% |
| Installation and Commissioning | Site readiness, shaft tolerances, installation sequence, testing, handover, and local-authority inspection support. | Require a site survey before production, an installation method statement, inspection and test plan, commissioning checklist, and documented handover acceptance criteria. | Approved shop drawings, interface schedule, method statement, inspection records, test certificates, as-built documentation, and operator training records. | 6% |
| Commercial and Total Cost of Ownership | Purchase price, installation, energy, maintenance, consumables, downtime, modernization, and disposal costs. | Compare at least a 15–25-year lifecycle model rather than the initial quotation alone; use identical assumptions for operating hours, electricity price, maintenance visits, and major component replacement. | Itemized quotation, warranty terms, maintenance-price schedule, energy assumptions, spare-parts pricing, modernization scenarios, exclusions, and payment milestones. | 10% |
