Current Issues of BIM-based Design Change Management, Analysis and Visualization

The BIM-based design process is dynamic in its nature as the models typically need to evolve. This paper addresses the problems of a BIM-based design change analysis, design change management and visualization of the changes made to BIM models. A concise discussion of the general problems of design change management in terms of BIM is presented. The authors also briefly discuss the current advancement of native BIM tools and their functionalities dedicated specifically to design change management; namely, tracking and analysis of design changes on the basis of BIM models. Subsequently, a number of examples are presented to illustrate the results of recent developments in the visualization of design changes.
