This gap in the way BIM is thought of has been something that has bothered me recently. The AEC industry continues to amaze me with how it manages to create new ways to remain the same. I have seen a number of instances lately of missed opportunities for BIM to be employed for a variety of reasons that amount to no reason at all. Each instance has a similar characteristic however. Someone involved in the process employed the "regular" way of doing things because to them BIM was not what they do. They didn't leave it out on purpose. They were just never reeducated with the understanding that BIM is the way we build. And so what ends up being left is a process that still works and still may have BIM elements included, but falls short of the true potential a good BIM workflow can offer.
So what can you do about it? You need to work to instill the idea in every person that BIM is not a novelty or luxury item. BIM is not something that a project doesn't really need but is nice to have. The idea that there are "BIM people" and then there is everyone else, needs to be dispelled. I know that for the audience of this blog I am probably preaching to the choir. But if you are an individual that has found yourself saying, "I'll just set this project up the way I always have and once it gets going I'll see how the BIM people can help." then you might want to reconsider the way you think. You're probably missing out on some good opportunities.
