This book is a very good way to either get started understanding BIM, or to use as a review module for those in the field who have been using such methods for a while. In fact this field is so hot, the book got stolen right off my seat when I took a head-break on the airplane. Sad, but now I get to write that off and buy an new copy. Hold on tight around the office too. Once I do get more than 3/4 of the way through I'll come back and complete a more detailed review. ~ BDH
