Bentley and Autodesk Announce Historic Interoperability Agre

There were several points that I liked about the article.
1. The quote from U.S. National Institute of Standards and Technology study that suggests that $16 billion is spent on difficulties because there are not standards.
2. The mention of BIM (Bentley and Georgia Tech name) and Revit (Autodesk) will start to have more impact on AEC as the maturity and use of the products improve.
3. The inclusion of the Chicago Spire was good.
4. and finally the link to the McGraw-Hill article on Construction
Thanks
