BLogCHAIN: PROOF-OF-CONCEPT AND PILOT TESTING OF A BLOCKCHAIN APPLICATION PROTOTYPE FOR CONSTRUCTION LOGISTICS IN SWEDEN*
Chalmers University of Technology, Sweden
Blockchain technology has a potential for construction logistics, also within Sweden. In this paper, a proposal of a blockchain system and its practical implementation is presented (the BLogCHAIN prototype). Its was preliminarily tested during the early construction of a school in Sweden, in November-December 2020. Methodologically, we reviewed studies on blockchain for construction logistics, interviewed the BLogCHAIN testers (suppliers and contractor’s operatives), and understood the test’s practical outcomes through sociomateriality. Our results include the confirmation of envisioned benefits when implementing BLogCHAIN (e.g. reducing accounting rework), but also a simplification from its initial conceptualization, mainly due to rigidly established work practices.

COMBINING BLOCKCHAIN AND BPMN COREOGRAPHIES FOR CONSTRUCTION MANAGEMENT
1DICEA, UNIVERSITA' POLITECNICA DELLE MARCHE, Italy; 2DII, UNIVERSITA' POLITECNICA DELLE MARCHE, Italy
Blockchain is considered a key technology of the current digital revolution and its application is spreading from cryptocurrencies to disparate processes requiring notarization. The well-known independence and contraposition of stakeholders in the AECO sector made DLT applications the hoped-for means to trust each other.
Construction site management due to its complexity and the pluralism of the actors involved can be modelled as a BPMN coreography of intra-organizational processes.
This aims of the work here presented is the exploitation of blockchains and smart contracts as tools to notarize the state of each intra-organizational process and to enforce compliance with the choreography
