What Is a 7D Digital Twin?

Short answer. A 7D digital twin is a 3D model enriched with schedule (4D), cost (5D), sustainability (6D) and facility and asset management (7D) data, bound to live operational data. One model then supports design, construction, handover and decades of operations.

How do the dimensions build up?

  • 3D: geometry of every element
  • 4D: construction schedule
  • 5D: cost
  • 6D: sustainability and energy
  • 7D: facility and asset management data

Why does 7D matter for operators?

Most BIM stops at 3D, and geometry alone cannot answer an operational question. At 7D the model becomes the operations system of record, with no re-survey, rebuild or data loss at handover.
