Building Information Modeling (BIM) is a relatively new term in the construction industry and despite its widespread adoption, definitions of the term still differ widely among the industry’s professionals, designers, engineers and software vendors. The first objective of this thesis is to define BIM and to assert whether its emergence and adoption is a simple matter of software evolution or a paradigm shifting process that can lead to better designed and constructed projects. Design and construction of buildings is a complex process that depends heavily on the communication and collaboration among all those involved. The quality of the information used is therefore of the highest importance and should be of the highest standard. The use of two – dimensional, line – based drawings on which the industry relies makes that impossible. The drawing based work process is rendered obsolete and the need to shift to others means is obvious. Working on a model which carries all the building’s information is one of the industry’s answers to the information problem. The implications and the consequences that this shift will have on the architectural design process are profound and not yet fully realized. We can argue though that the shift of the effort to the earliest stages of the design process and the architect’s ability to work with more information earlier can lead to overall better designed projects, realized in shorter timelines and smaller budgets.
