Abstract

In the subcontractor (Sub) procurement process, the General Contractor (GC) can seek potential Subs from a limited pool based on their past relationships. This challenges new subcontractors who are qualified for the project but lack prior relationships with the GC. Furthermore, it creates a relationship bias that impedes the creation of a constructive business environment where potential Subs are encouraged to enhance their quality and compete fairly to secure procurement contracts. To address these challenges, this paper proposes a proof-of-concept of a transformational procurement system that integrates blockchain-enabled smart contracts and Building Information Modeling (BIM)-based project management. The proposed system can facilitate the data-driven automatic matching of GC with Subs, thus extending the pool of Subs and eliminating relationship bias in the procurement proceedings to enhance the effectiveness and fairness of the procurement. It contributes to the body of knowledge by enabling a digitalized and automated subcontractor procurement leveraging blockchain.

消除关系偏差的 BIM 和区块链自动采购系统 (BBAPS)
在分包商(Sub)采购过程中,总承包商(GC)可以根据他们过去的关系,从有限的资源库中寻找潜在的分包商。这就给那些有资格参与项目但与总承包商缺乏以往关系的新分包商带来了挑战。此外,它还造成了一种关系偏见,阻碍了建设性商业环境的建立,在这种环境中,潜在的分包商被鼓励提高自身质量,公平竞争,以获得采购合同。为了应对这些挑战,本文提出了一个转型采购系统的概念验证,该系统集成了支持区块链的智能合约和基于建筑信息模型(BIM)的项目管理。所提议的系统可促进数据驱动的 GC 与 Subs 的自动匹配,从而扩大 Subs 的库,并消除采购程序中的关系偏差,以提高采购的有效性和公平性。该系统利用区块链实现了分包商采购的数字化和自动化,为相关知识体系做出了贡献。
