Handover disputes often trace back to missing QC evidence. These KPIs and checklist categories help contractors and consultants close projects cleanly.
Installation quality is more than a pass/fail ride test. Building owners expect documented evidence that safety circuits, door systems, ride comfort and controller configuration meet specification.
Core QC categories
1. Safety & code compliance
Verify emergency communication, overspeed protection, unexpected car movement protection and buffer clearances. Record serial numbers and firmware versions for audit trails.
2. Door performance
Measure open/close times, nudging, re-opening on obstruction and landing gaps. Door faults dominate callback statistics—catch them before handover.
3. Ride & leveling
Rated speed, acceleration profiles and floor leveling within tolerance reduce tenant complaints. Use consistent measurement points on each representative floor.
4. Documentation
As-built drawings, risk assessments, maintenance manuals and spare parts lists should be linked to the QC sign-off pack.
Digital checklists—such as those in Liftaro Quality Control—let teams score items by weight, flag failures early and archive results per project.
