What do we add to change a five-dimensional (5D) Building Information Modeling (BIM) design into six-dimensional (6D)?

6D BIM adds information used for operating and maintaining the building. If a model already includes cost data (the 5D level), the next dimension brings in maintenance-related information—spare parts, warranties, preventive maintenance schedules, operation manuals, and links to a facilities management system—to support ongoing lifecycle management. Schedules are tied to time (4D), and occupancy is a use attribute rather than the defining 6D addition, while estimates stay with 5D. So, maintenance information is what you add to move from 5D to 6D.
