为了更好地管理模块化建筑项目的场外和现场施工进度，资产跟踪越来越必要。预制厂部件的延迟交付将推迟施工进度，造成经济损失、纠纷和变更单。为了透明和准确地认证这些作品，防篡改的数字资产跟踪系统非常重要。由于其记录的不变性和可信度，区块链可能是潜在的解决方案，而基于建筑信息建模（BIM）的数字孪生模型可以提供有关建筑资产的丰富语义信息。然而，目前的研究还没有实现足够的自动资产跟踪和变化可视化的合作。为了解决这个问题，本文提出了一个基于智能合约的集成BIM区块链框架。首先，资产及其语义信息，以及施工进度及其相关活动之间的依赖关系，将自动从BIM传输到区块链，并生成相应的QR码以附加物理资产。由于他们的物理跟踪数据在区块链中更新，如果有任何延迟，潜在的变化将通过执行编译的智能合约自动传播到所有受影响的活动。一旦利益相关者验证了这些更改，受影响的活动和相应的资产将在4D环境中自动可视化，以便及时通知和协作。我们还开发了一个原型系统，以验证该框架的可行性，在一个可信的和可追溯的方式。
Asset tracking is increasingly necessary for better management of offsite and onsite construction progress for modular construction projects. Delayed delivery of elements from prefabricated plants would postpone the construction progress, resulting in economic losses, disputes, and change orders. To certify these works transparently and precisely, a tamperproof digital asset tracking system is important. Blockchain can be the potential solution due to the immutability and trustworthiness of its record, while building information modeling (BIM)-based digital twins can provide rich semantic information on building assets. However, current studies have not achieved sufficient collaboration for automatic asset tracking and change visualization. To address the limitation, this paper proposes an integrated BIM-based blockchain framework based on smart contracts. First, assets and their semantic information, as well as construction schedule with the dependency among their relevant activities, are automatically transmitted from BIM to the blockchain, where corresponding QR codes are generated to attach physical assets. As their physical tracking data are updated in the blockchain, if any delay, the potential changes will be automatically propagated to all affected activities by executing compiled smart contracts. Once stakeholders certify these changes, the affected activities with corresponding assets are automatically visualized in the 4D environment for timely notification and collaboration. We also develop a prototype system to validate this framework’s feasibility in a trusted and traceable way.
