What is it about?

Construction 4.0 has become a buzzword since the penetration of building information modeling (BIM), cyber-physical systems, and digital and computing technologies into the construction industry. Among emerging technologies, distributed ledger technology (DLT), specifically blockchain technology, is a powerful business enhancer whose potential can disrupt projects, AEC (architecture, engineering, and construction) firms, the construction supply chain, and in a broader sense, the whole construction industry. This technology has not reached the plateau of productivity due to several barriers and challenges. In this regard, this study addresses the most critical challenges to achieving sustainability in the construction industry.

Why is it important?

This study is important from several aspects. It is for the first time that the Ordinal Priority Approach (OPA) is employed in a real-case study. Second, this novel method determines the weight of sustainability attributes and barriers simultaneously. Third, a new approach is taken in the "Blockchain technology," 'Construction Industry," and "Sustainability" context. Fourth, a framework of blockchain barriers is presented.

Perspectives

The results show that DLT (i.e., blockchain) implementation needs (i) infrastructure for data management, (ii) advanced applications and archetypes, (iii) customers’ demand, interest, and tendency, and (iv) reporting capabilities. Solving high-ranked challenges is the key to social sustainability from the aspects of “supply chain management and procurement”; “transparency, anti-corruption, and anti-counterfeiting”; and “fair operation and honest competition.”
