Which BIM dimension is typically associated with facility management after turnover?

• A. BIM 7D model
• B. BIM 3D model
• C. BIM 4D model
• D. BIM 5D model

Answer: (A)

The dimension used for facility management after turnover is the 7D BIM model. After a project is handed over, building operations rely on a data-rich model that goes beyond geometry and construction planning. The 7D dimension adds the long-term operation and lifecycle information needed by facilities management—things like equipment specifications, maintenance schedules, warranty details, space data, and performance metrics. This data can be linked with maintenance systems and other FM tools to support ongoing repairs, replacements, energy performance tracking, and asset management. In contrast, the basic 3D model handles geometry, 4D adds construction scheduling, and 5D adds cost; these are more construction-focused and don’t fully support post‑turnover operations.
