Breakpoints in Data Continuity Across Construction Reuse Projects

Abstract: This study investigates where and why material identification and digital representation fail to persist across reuse life cycles. Digital material tracking in circular construction is commonly organized through separate data pipelines for logistics and design, resulting in discontinuities as building elements move between projects. A unified analytical framework is proposed and used to define six recurring classes of breakpoints in data continuity. These breakpoints are empirically identified and analyzed across eight construction reuse case studies. The findings establish a systematic breakpoint typology and provide recommendations for continuity-oriented data infrastructures that support traceable material reuse in construction.
