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
