Building Information Modelling (BIM) Execution Plan (BEP) is a complex process model used to represent the lifecycle process in modern building projects. The complexity is caused by the system of concurrent processes involved that are interdependent by means of information exchange requirements in the form of intermediate models and other information. Process oriented BEPs set the baseline for developing process maps which gives a visual representation of the interrelationships between and sequence of processes. But, there are different levels of details possible for processes and when details are more, process maps consumes enormous space making it unfeasible. This paper discusses various levels of details in which the BIM processes can be represented and demonstrates the application of Multi Domain Matrix (MDM) along with process maps. Analysis of MDM reveals more about the process architecture than visualisation in the process maps.
