4. BIM is not a utopia
5. BIM is not a bunch of Standards
6. BIM is not a way to get others to do your work
7. Learn from UK BIM Approach - Digital
What is True BIM?
1. 5D enabled models must be accurate
2. Consistency of Models and 2D Drawings

1. True BIM
Combined Services Model
Combined Services Drawing from BIM Models
2. True BIM Process – Everyday BIM
Professionals use BIM, modellers operate BIM

4. nD BIM
4. BIM Use Matrix
BIM is not a Utopia
Some BIM Uses are conflicting with each others
Define EIR
5. BIM is not A Bunch of Standards
Use if the standard is beneficial, or forget it
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
6. BIM is not A WAY TO GET OTHERS TO DO YOUR WORK

6. Architects must determine the door, window, finishes asap for QS
Every participant has a duty to provide updated information to BIM for others to use
UK BIM Documents specify Information Management far more than BIM process
7. UK BIM Strategy - Digital
