Abstract:

The transition from a linear economy (take-make-dispose) to a circular economy in the construction industry (i.e., circularity in construction) necessitates adopting deconstruction instead of demolition. Deconstruction planning methods need to be investigated to facilitate this transition. Successful deconstruction planning requires considering various information to capture the destiny of the extracted building’s product. Therefore, there is a dire need to propose a deconstruction planning method that is interoperable, easily integrated with various data sources, and conducive to stakeholder collaboration. To this end, this paper aims to propose a deconstruction planning method using Knowledge Graph (KG) technology. Firstly, the authors extracted the characteristics of the facility to be deconstructed, including hosting and hosted relations of components. Secondly, the characteristics of the facility’s products were transformed into a KG. Finally, disassembly rules were defined, and new knowledge was inferred via automated reasoning. The developed method was tested on two case studies, involving two-dimensional and three-dimensional representations. The results aligned with other methods in the literature, requiring fewer inputs.
