This study investigates blockchain technology (BCT) to address the issues of lack of design liability control and a few data-related issues using a design science research method. The current information exchange processes in the New Zealand construction industry were mapped to identify the critical transactions that may benefit from record-keeping on the blockchain. Next, a prototype was designed to demonstrate and evaluate the proposed BCT integrated process models. Three key project processes, design review, design coordination and request for information; and two potential conflict scenarios during and post-construction were simulated as part of the evaluation.

This study explores a blockchain technology-based solution to improve trust in data exchange in BIM following a case-study analysis of a commercial tool called BIMCHAIN. It builds a list of eight essential functional requirements of an effective blockchain tool integrated into a BIM workflow.

This paper reviews the literature on the issues of information exchange in a Building Information Modelling (BIM) environment and explores the concept of Blockchain Technology and its connection with BIM.
