Why use BIM ?
CAD and GIS• Boundaries• 2D or 3D• Fragmented• Obscure Meaning
DOCUMENT / IMAGE
• Not usable
• Not re‐usable
BIM• “Mug”• Shapes and symbols• has Materials• has Capacity• kind of Equipment• touches “Table”
Sharing …
• When ?• now, • later, • again, • continuously
• With whom ?
• Yourself,
• Your colleagues
• Project partners and contractors
• Clients
• Regulators
