Abstract:

In recent years, designers have often become the target of accountability in the aftermath of engineering accidents. With the BIM model becoming the original material for engineering drawings review and archiving, novel solutions are necessary to prevent engineering quality accidents from their source. Consequently, a design responsibility and right traceability system integrating BIM and blockchain was proposed. Blockchain, a decentralized database, is tamper-proof and traceable, and has been successfully utilized in the field of quality traceability. Within the framework of a distributed application, an alliance chain for BIM metadata storage was proposed based on Ethereum technology, and the degree of decentralization was reinforced through three types of nodes: administrator, designer, and supervisor. In order to resolve the problem of excessive BIM model volume, the third-party platform BIMFACE was used as an external database, filling the gaps in supporting formats and practical applications when integrating blockchain with BIM. Hash algorithm-based integrity check can prevent third-party tampering with the model. Concurrently, the system boasted great expandability, enabling collaborative work functions such as online browsing and model description, and can accommodate additional application scenarios in the lifecycle of BIM products in the future. An application case of a university’s Xiong’an campus has demonstrated the system’s ability to permanently record and accurately trace the design process.

Key words: blockchain, building information modeling, design responsibility and right, traceability, collaborative work
