Blockchain in building logistics: emerging knowledge, and related actors in Sweden
Paper i proceeding, 2019
Large building projects involve complex on-site logistics regarding materials and subsystems, often encompassing hundreds of vehicles handling incoming and outcoming goods and requiring precise timing and space handling. Such a material flow is generally decoupled from the respective economic flow; however, the integration of the two could, among others, foster a holistic overview of the full construction project production, facilitate the collaboration of the supply chain stakeholders, and optimize constructability. Blockchain technologies can enable an integration of these flows by using the distributed ledger facility inherent in a decentralized blockchain network, as well as smart contracts. This paper aims at reviewing the emerging knowledge on blockchain in construction and identifying different constellations of companies and flows in digital building logistics. Theoretically, the paper draws on a sociotechnical approach, which views the development of digitalization as an intertwined social and technical process, where technology is co-shaped with practice. Building on a literature review and interviews and dialogues with actors active in building logistics within Sweden, at least three digital building logistics constellations with the potential to implement blockchain solutions are identified: (1) large contractors integrating building logistics internally, to overcome transaction challenges and maintain power over business-critical supply processes, (2) clients employing independent third-party logistics consultants acting as convenors of different interests in the building logistics setup, and (3) other thirdparty actors such as construction equipment suppliers, offering customised digital building logistics solutions.
