Process Modeling for BIM Jiří KAISER Faculty of Civil Engineering, Czech Technical University in Prague, Thákurova 7, 166 29 Prague 6, Czech Republic

Objectives Identification of modeling languages used for process modeling for BIM Identification of syntax mistakes in process models that are in contradiction to used modeling language specification (missing elements or connectors, their misuses and misunderstandings) Identification of insufficient information in process models Identification of non-standard syntax (extensions allowed by modeling language specification)

Methods Review of process models in: BIM Execution Plan (BEP) manuals and templates Information Delivery Manuals (IDMs) Check process models with specification of used modeling language Summarize, present and discuss found problems

Results Process models are usually based on Business Process Model and Notation standard (BPMN) but often handle it in a way that is in contradiction to the BPMN specification. Process models don't contain important information. The way of adaptation of BPMN standard often leads to simplification at the expense of process model accuracy. Examples of typical problems found: Data Objects connected by Sequence Flows or Message Flows, Data Object connectors connected to Sequence Flows, missing Gateways, connecting objects by Message Flows within the same Pool, missing Sequence Flows between Lanes, missing End Event, using Data Associations passing border of Pool.
