Thinking of building information modelling (BIM) as a revolutionary 3-D tool which can transform the way construction companies, consulting engineers, contractors and governments can prepare and manage their building and infrastructure projects, would be right - and it would be wrong. Christophe Castaing, director of digital engineering planning at EGIS, and chair of EFCA task group on BIM, said, "It is not a 3-D tool. I could have had a 3-D mock-up of a construction plan 25 years ago. That is not the key with BIM. "It is the capacity to share information. It is a process for delivering information. It is digital, and it is collaborative." However it is defined, BIM has long reached the point of no return.
