Process modeling

Abstract

An important part of the BIM methodology is the consideration of processes that create, modify, use or pass on digital building information. The planning and coordination of such BIM processes is one of the many important tasks of a BIM manager. It defines which tasks are to be executed by which persons in what order. In particular, the individual interfaces must be clearly specified. A lean and transparent process definition helps support the introduction of BIM methods significantly. This chapter provides an introduction to formal process modeling, including the modeling languages Integration Definition for Function Modeling (IDEF) and Business Process Model and Notation (BPMN), which are widely used today in the field of BIM process modeling.
