The process of constructing structural systems produces a huge amount of documentation that traces human activities on a construction site. While the building information modelling approach introduces common data environments (CDEs) to support document management, communication between them is limited, and mainly involves the use of email and activities susceptible to human error. This paper proposes a proof-of-concept for the integration of blockchains and smart contracts into information flows used in various CDEs. The focus of the proposal is on reducing human error and increasing the reliability and transparency of decision-making processes on construction sites pertaining to the structural system. To this end, the proof-of-concept introduces smart contracts that have different levels of complexity, with the advanced version comparing information exchanged with data gathered by IoT sensors on site. A first implementation of the proposal is also presented.

构建结构系统的过程会产生大量记录建筑工地人类活动的文档。虽然建筑信息建模方法引入了通用数据环境 (CDE) 来支持文档管理，但它们之间的通信是有限的，并且主要涉及使用电子邮件和易受人为错误影响的活动。本文提出了将区块链和智能合约集成到各种 CDE 中使用的信息流中的概念验证。该提案的重点是减少人为错误并提高与结构系统相关的建筑工地决策过程的可靠性和透明度。为此，概念验证引入了具有不同复杂程度的智能合约，高级版本将交换的信息与现场物联网传感器收集的数据进行比较。还介绍了该提案的第一个实施方案。
