Building Information Management or BIM is a process not a product

"We need BIM. How much does it cost and when can you install it?" This is a direct quote from a call I received not too long ago. I actually get questions close to his one on a monthly basis. I hate to answer a question with a question, but that's the only thing to do in this situation. What is your understanding of what BIM is?

BIM is a building design methodology characterized by the creation and use of coordinated, internally consistent computable information about a building project in design and construction.

BIM is Communication between all parties who work on a building project.

BIM is a workflow that shares information between the Design, Analysis, Construction, and can even stretch into the Ownership of a building.
