Originally, when I thought about writing this post, I was going to link to a number of reputable sites that break this rule. Then I thought about it again, and decided to give these organizations a chance to clean up their act.
The offense? BIM model. If you are wondering what is wrong with saying BIM model, you too are guilty. Think about it: Building Information Model Model? Hopefully, this will teach you your lesson, and you can spread the word to the rest of the industry. What are you supposed to say when referring to your group of Revit (or equal) files that comprise a Building Information Model? Just try saying BIM, or the BIM, or even the model.
As for the organizations I referred to above, I will compromise: click!
