Response?
The Disclaimer
This model looks great so you can look at it but you can’t use it for anything or rely on it for anything which includes, but is not limited to, everything.
If you use it for anything anyway then you have to pay my lawyers anything they want if I get sued for anything related to your use of the model for anything.
Have a nice day.

Response?
Disclaimer approach:•Some of it’s not reliable so don’t rely on any of it.
Specified-Use Approach:•Some of it’s not reliable so only rely on what I say you can

DETAIL = Input*
DEVELOPMENT = Reliability

Conclusion
• Planning versus plans• Don’t just “do BIM”• Measure successful objectives• Get involved with open standards
Plans are worthless. Planning is essential. - Dwight D. Eisenhower
