Process Framework of Information Modeling for BIM Execution Planning

Modern construction projects are (unlike earlier projects) very complex and complicated. Hitherto approaches are therefore proving to be problematic or even unusable. Therefore new approaches are created, usually based on the modeling methods. One of such methodology is the methodology BIM (Building Information Modeling), which attempts to cover the entire life cycle of a construction project. This methodology has a boom in recent years. However, there appear objective difficulties that impede wider application of the methodology. In this article I will deal with one of these problems. This is a vague process model based on non-standard methodology for process modeling. The resulting process models show considerable ambiguity and do not provide the information that we rightly expect from such a process model. The aim is to identify the major problems of the methodology used and describe how they have (or could have) an impact on the comprehensibility of the existing process model. Then we will form a basis of methodology really useful for a comprehensive description of the process model. This methodology will be based on existing and sophisticated methodology BPMN, which will eventually domain-specifically adapted to the needs of BIM and construction.
