Came across this while looking for information on 64 bit performance in Revit...it's an artical from DPR construction, Transcending the BIM Hype: How to Make Sense and Dollars from Building Information Modeling:
The article is written by Eric Lamb, Dean Reed and Atul Khanzode of DPR Construction, Inc.
Even though this is a Bentley sponsored site, it speaks volumes as to the importance of setting the correct expectations of BIM.
Very well written - nice work guys!!!
thanks - David B.
