The document summarizes a presentation about BuildingSMART International's Basic IDM initiative in the Netherlands. The initiative aims to establish common agreements for open BIM standards to improve information exchange and coordination between stakeholders in the construction industry. Key points of agreement for the Basic IDM include modeling conventions for basic elements like walls, doors and windows. The initiative is led by a diverse group of members from the construction industry and aims to ultimately enable reuse of BIM data for applications like construction planning simulation.

10. Model positions did not match

11. No integral project agreements

12. Translation: “Unreliable Ice, Acces prohibited”
Unreliable model information
“Models for information purposes only”
“Details not generated from the model”
“I'm not sure the information in te
model is correct”
“Use at your own risk”
“Paper drawings are leading”

13. Information is not complete
No value where the material should be filled in Unknown entity

14. Different values about the structural class in one object
Which Quality?
C30/37?
Or
C35/45?
Or
C53/65?

21. Philosophy behind the Basic IDM
• No new invention,
• Adopt Open Standards!
• Keep It Simpel Stupid (KISS)
• 80/20 rule
• Step 1: Agreement on BIM Basic IDM
• Step 2: Engage on BIM Basic IDM and get it widely accepted.
