区块链和智能合约是加速循环经济在建筑过程中扩散的措施。然而，覆盖循环供应链网络结构、业务流程、产品等各个方面的综合解决方案仍然缺失。本文试图通过提供一个可行的解决方案来解决区块链在施工过程中不连贯的本质，从而弥合这一差距。根据设计科学研究（DSR）的总体方法，根据DSR的五阶段程序创建解决方案：(1)问题识别，(2)处理建议，(3)处理设计，(4)评估和(5)结论。研究结果表明，提出的解决方案在几个方面是新颖的；它：(1)使建筑从业人员能够在安全和不可变的媒介上分享他们的建筑构件信息；(2)使政府当局（即市议会）能够跟踪危险产品/材料的处理和交付；(3)通过在区块链网络中促进“设计师对设计师”和“设计师对资产所有者”的合作，支持上游循环经济设计；(4)支持开发“可重复使用的BIM系列库”，鼓励设计师在设计中使用这些项目。除了这些贡献之外，本研究为未来的研究提供了一些沃土。最重要的是，未来的研究可以通过将这里提出的解决方案与物联网（IoT）集成来提供全自动系统；研究人员在各种环境和现实生活项目中验证了所提出解决方案的可行性。
Blockchain and smart contracts are measures to speed up the diffusion of circular economy into construction processes. Nevertheless, integrated solutions that cover all the aspects of circular supply chain including network structure, business processes, and the products are still missing. This paper is an attempt to bridge this gap, through offering a workable solution to address the disconnected nature of blockchain adoption across construction procedures. Informed by the overall approach of design science research (DSR), the solution is created following the five-staged procedure of DSR: (1) problem identification, (2) treatment suggestion, (3) treatment design, (4) evaluation and (5) conclusion. Findings establish that the proposed solution is novel in several ways; it: (1) enables construction practitioners to share their building components information on a safe and immutable medium; (2) enables government authorities (i.e., city council) to track the treatment and delivery of hazardous products/materials; (3) supports the upstream circular economy design through fostering collaboration among ‘designers to designers’ and ‘designers to asset owners’ in a blockchain network; and (4) supports developing ‘a bank of reusable BIM families’, encouraging designers to use these items in their designs. Apart from these contributions, this study provides some fertile ground for future research. Chief among all: future studies can provide fully automated systems through integrating the solution presented here with the Internet of Things (IoT); and researchers that validate the workability of the proposed solution across various contexts and real-life projects in exposure to various settings and peculiarities.
