Why BIM for Digital Building Permits?

1. The Problem with Traditional Submissions

• 2D drawings are reviewed manually
• Information is spread across many files
• High risk of missing or inconsistent data
• 2D drawings are not machine readable, BIM is.

2. What BIM Changes

• One digital model contains geometry and information
• Data is structured, consistent, and machine-readable
• The same model can be reused across project permitting
• Less interpretation, more clarity

3. What “Digital Permit” Means

• Permit review supported by digital models, not only drawings
• Rules can be checked automatically or semi-automatically
• Faster reviews and clearer compliance decisions
• Better traceability and transparency

4. How BIM Supports Digital Permits

• Accurate building geometry (areas, dimensions)
• Clear classification of building elements
• Embedded properties required for code checks
• Ability to run automated or assisted compliance checks

5. Benefits for Consultants

• Clearer requirements from authorities
• Faster approval cycles
• Better internal quality control

6. Benefits for Authorities

• Reduced manual checking effort
• More consistent and objective decisions
• Better data for reporting and analytics
• Foundation for future digital services

7. Key Message

BIM is not about 3D models.
It is about structured, reliable data that enables digital permitting.
