Semantic approach to formalize knowledge from building renovation domain: application to the IsoBIM project

Overview & Synopsis

The introduction of semantic technologies to the construction field is a concept that has been explored many times over the last few years. However, building renovation tends to be overlooked when talking about advancements in construction. Even if, Renovation projects consists 57% of construction activities, the renovation field is still the least developed. Information exchange between the project's different actors is still a persistent problem. Therefore, this paper proposes a semantic approach that aims to formalize knowledge from the renovation domain, using BIM as the information source, to design a dynamic digital representation of a renovation project (construction digital twin). In this context, and to highlight the remaining scientific questions, a case study of a renovation project is used to assess the current state of the renovation process and to test the ontology under development.
