Introduction of the Ontology for Chronological Construction Processes (OCCP)

Abstract: The Ontology for Chronological Construction Processes (OCCP) provides a semantic foundation for a chronological structure aimed at managing information in the Architecture, Engineering, Construction and Operations (AECO) sector. Based on the W3C TIME ontology (Cox et al., 2006), the OCCP introduces a lifecycle-oriented concept tailored to Building Information Modelling (BIM) workflows and advances the accurate management of time stamps by introducing phases, cycles, milestones and transitions to ensure traceability of states throughout and beyond the lifetime of assets. This paper describes the concept and composition of OCCP, its SHACL-based validation rules, and provides an example to demonstrate its practical application.
