Methodology for automated generation of 4D BIM Montaser, A.; Moselhi, O.


Lack of adequate visualization of project construction operations often causes project parties to struggle with large amount of data. 3D Building Information Modeling (BIM) is a static model, built for representing the geometry of a constructed building and its respective information. However, construction processes are dynamic and require dynamic representation. 4D BIM is gaining more momentum in construction research and in industry. There are commercial packages that can generate 4D BIM and numerous researchers have used 4D BIM in their research. However, related literature does not disclose the methodology used or the know-how of creating 4D BIM. This paper presents an automated methodology and describes how to construct a 4D BIM. The automated methodology maps the 3D BIM objects to project schedule activities through a newly added attribute to each 3D BIM object. As such, different groups of objects within the 3D BIM are assigned to different activities. For each group, a series of decisions are made to classify whether it belongs to completed activity, activity in progress or activity to be executed in the future. The developed methodology was implemented in prototype software. Autodesk Revit has been customized so that the integration between 3D BIM and project schedule be applied using Revit Application Programming Interface (API). The developed automated methodology and software were applied to a construction project in Montreal area to demonstrate its use. The developed methodology is straightforward and easy to use. It is expected to facilitate the utilization of 4D BIM in research and in practice.
