Integration of semantic temporal information in BIM using ontologies

Abstract: Model-based planning requires an extensive amount of information about the environment, inventory and requirements of the planned object. Thereby, temporal information is important to be considered for planning, construction and maintenance, but in current approaches temporal information is only defined through non-semantic datasets, which lack contextual meaning. To semantify time-data used in BIM projects, the authors propose the concept of combining existing models using ICDD and adding an Ontology for Chronological Construction Processes (OCCP) to record and implement structured temporal information of the entire life cycle and use it from the start of planning until deconstruction and even beyond.
