We are considering an elevator modernization to improve reliability, accessibility, and safety. The decision is not only about price: we need to compare scope (controller, doors, cabin upgrades), warranty terms, maintenance response times, and how the contractor manages resident disruption and safety during works.
Because elevator downtime is a major impact (especially for residents with mobility constraints), the schedule window is part of the decision. This proposal demonstrates Concorder by using ranking for bid approval (each bid includes detailed HTML scope and targeted pros/cons), plus a separate vote on acceptable work windows using date ranges. Attachments reference the EU lift safety framework so residents can ask the right questions about compliance and documentation.
Rank the bids, then choose the work windows that are feasible. In comments: add resident constraints (strollers, medical needs), preferred notice period, and any observed current issues (breakdowns, door faults, leveling problems).
New controller and drive, door operator replacement, leveling sensor upgrade, cabin lighting and ventilation refresh. Includes commissioning tests and 24-month parts warranty.
Maintenance SLA: on-site within 24–48 hours for stoppages.
Controller modernization plus full cabin refresh: wider door timing logic, new COP/buttons with visual/audio signals, improved leveling performance, and cabin interior renewal.
36-month warranty on selected components, quarterly performance report.
Phase 1: controller + door operators now. Phase 2 (optional later): cabin refresh and advanced signaling. Includes commissioning tests and 18-month warranty.
Lower upfront cost, but more project management if Phase 2 is executed.
Summary of essential safety requirements and conformity assessment for lifts.
