论文摘要
本文提出了一种基于智能合同的解决方案，用于自动管理建筑进度付款。它弥合了付款（现金流）与现实捕获技术和构建信息建模（BIM）实现的工作站点（产品流）之间的差距。该方法消除了对现有付款应用程序的集中式和严重介导的机制的依赖。使用内容可寻址文件共享以分布式方式存储施工进度；它被广播为智能合同，该合同可自动化链上支付和解和留置权的转让。该方法已成功地用于在两个商业建筑项目中处理7个分包商的付款，其中使用配备摄像头的无人驾驶汽车（UAV）和配备了激光扫描仪的无人接地车辆（UGV）进行了进度监控。结果显示了该方法增加付款频率，粒度和透明度的潜力的希望。本文结束了关于项目管理的影响的讨论，并引入了新的项目模型作为单身人士机器。
This paper presents a smart contract-based solution for autonomous administration of construction progress payments. It bridges the gap between payments (cash flow) and the progress assessments at job sites (product flow) enabled by reality capture technologies and building information modeling (BIM). The approach eliminates the reliance on the centralized and heavily intermediated mechanisms of existing payment applications. The construction progress is stored in a distributed manner using content addressable file sharing; it is broadcasted to a smart contract which automates the on-chain payment settlements and the transfer of lien rights. The method was successfully used for processing payments to 7 subcontractors in two commercial construction projects where progress monitoring was performed using a camera-equipped unmanned aerial vehicle (UAV) and an unmanned ground vehicle (UGV) equipped with a laser scanner. The results show promise for the method's potential for increasing the frequency, granularity, and transparency of payments. The paper is concluded with a discussion of implications for project management, introducing a new model of project as a singleton state machine.
