BIM is not a Utopia
Some BIM Uses are
conflicting with each
others
Define EIR

13. 5. BIM is not A Bunch of Standards
Use if the standard is beneficial, or forget it

14. 5. BIM Standards
There are only THREE Standards in BIM
1. NBIMS-USTM
- National BIM Standard, US
e.g. Minimum BIM Requirements in line with the
Capability Maturity Model.
2. IFC – Industry Foundation Class
3. Classification of materials and equipment
Others are guidelines, practice, sample/template, protocol

16. 6. BIM is not A WAY TO GET
OTHERS TO DO YOUR WORK
