近年来，很少有人提出基于区块链的进度支付方法来改善传统的建设项目支付流程。基于区块链的方法需要将链下真实的世界信息连接到区块链，这对于建筑项目来说可能是一个挑战。本文提出了一种新的建筑信息模型（BIM）集成智能合同进度支付管理系统，其中构建的BIM用于连接真实的世界与区块链。对建筑专业人员的调查结果表明，拟议的制度具有改进传统付款程序的巨大潜力，因为它加快了进程，并使进度付款不易发生争议，特别是对于一次总付项目。研究结果还表明，未来研究半自主BIM集成智能合同系统的潜力，可以加速BIM和智能合同技术在建筑行业的进度支付管理中的应用。
In recent years few blockchain based progress payment methods have been proposed to improve the traditional payment process for construction projects. The blockchain based methods require the off-chain real world information to be connected to the blockchain which could be challenging for construction projects. This paper presents a novel building information modeling (BIM) integrated smart contract progress payment administration system, in which as-constructed BIM is used to link the real world with the blockchain. Results of a survey of construction professionals revealed that the proposed system has a significant potential for improving the traditional payment procedure by accelerating the process and by making the progress payments less prone to disputes, especially for lump sum projects. The results also indicate the potential of future research on semi-autonomous BIM integrated smart contract systems to accelerate the adoption of the BIM and smart contract technologies for progress payment administration within the construction sector.
