Thanks Amonle. There's also one from McGraw-Hill from a few years ago - released Jan 2009 or 2010 which we heard presented at NIBS. That report was mostly about the use of BIM (estimated ROI, e.g.) as opposed to not using BIM.
I was curious to see whether the evaluations were deeper and less "conceptual" ("academic"?) than some previous pair-wise comparisons that I've seen, and more in-depth than some of Ms. Khemlani's previous reviews, and what the AIA concludes from this study. I was curious, too, about the methodology used: what role "intuitive interface" and other slippery terms played, what metrics were used, and what criteria various testers judged to be most important in their tools of choice. Guess I'd just have to pay to see that hand...
The bad news for AIA is that the thing is worth less each passing day, until it becomes a quaint museum-quality curiosity, like a review of VisiCalc might be now.
