||Consequences of a decision made by a planner (e.g. a project manager, or an engineer) within a collaborative environment can hardly be foreseen. For example, such a collaborative scenario is represented by a planning process in AEC. In particular, during certain planning stages alternatives have to be considered which significantly influence the overall result. Todays AEC planning procedures can be very much improved by predicting simulation methods to judge about the quality impact of certain design or planning modifications. Also, the proper interpretation of data is very crucial to give suitable insight into the characteristic consequences of individual planning decisions. This contribution presents an approach to achieve this goal by discussing needs, problems and implementation for the actual state of our research.
