Abstract

Blockchain, a peer-to-peer controlled, distributed database structure, has the potential to profoundly affect the current business transactions in the construction industry through smart contracts, cryptocurrencies, and reliable asset tracking. The construction industry has often been criticized for being slow in embracing emerging technologies and not effectively diffusing those technologies through its supply chains. Often, the extensive fragmentation, traditional procurement structures, destructive competition, lack of collaboration and transparency, low-profit margins and human resources are shown as the main culprits for this. As Blockchain makes its presence felt strongly in many other industries like finance and banking, this paper investigates how to prepare construction supply chains for Blockchain technology through an explorative analysis. Empirical data for the study were collected through semi-structured interviews with 17 subject experts and focus groups. Alongside presenting a SWOT (strengths, weaknesses opportunities, threats) analysis, the paper exhibits the requirements for and steps toward a construction supply structure facilitated by Blockchain.
