Abstract
Digitalization has gained recognition as a crucial factor for implementing circular economy principles in construction. However, digital platforms for circular construction do not adequately match supply and demand in the emerging secondary materials and products market yet. Therefore, this research questions how digital matchmaking platforms could be (re)defined to better support circular construction practitioners. By applying a participatory action research methodology with a technical assistance provider, the study employs a three-stage research design to comprehensively identify, collect, and react to stakeholders' needs in the French context, experiencing recent policy change. Our resulting butterfly matchmaking model defines two distinct, yet interoperable matchmaking loops: the first one matches auditors, contractors, and collectors for deconstruction, and the second one matches designers, contractors, and dealers for construction. This strategy presents a paradigm shift in current platform thinking by ensuring autonomy for circular construction and deconstruction as well as by providing a multi-sided matchmaking environment for key stakeholders' inclusion. Our proposition prompts platform developers to transition from mainstream project-centered matchmaking to a more holistic profession-centered matchmaking approach. By promoting tighter coordination between digitalization, policy, and practice, we contribute to the development of advanced digital matchmaking platforms, supporting the industrialization of circular construction. These results will be used to develop a functional prototype of a digital matchmaking platform for analyzing real business models.
