Barriers to BIM
The ultimate objective is to build an integrated BIM—a virtual building before we make expensive mistakes with concrete, glass and steel. But tradition, contractual separation, archaic laws, technical limitations, interoperability problems and culture hinder us.
Software and hardware constraints: A BIM model theoretically has unlimited ability to hold information. But any practical project model will fall short of what is theoretically possible. Despite faster and faster computers and more efficient software, the model slows down as it enlarges.
Cost practicalities: At some point, it becomes impractical to add detail to the model. We still assume the builder will use some judgment in the field. A drawing doesn’t need to show all the nail locations in a wood frame.
Universal adaption: The fruition of BIM will depend on widespread use by designers, contractors and manufacturers. But until trade contractors and manufacturers are operational with BIM, we will limp along with incomplete integration.
Interoperability: Any CM or PM that has managed a program that included multiple architects and multiple CMs has faced the frustrating problems of interoperability in trying to integrate data from different project management information systems. It is hard to share data between Autodesk’s Constructware, e-Builder and Meridian’s Prolog. The same problem exists with BIM software.
A fully integrated BIM model is a vision, not a reality. At current levels of development, architects engineers, consultants, builders and fabricators may have independent BIM models, legacy CAD systems and legacy paper systems. Those who use BIM software may not use the same programs
