As a potential solution to the problems of design liability control and data security, Blockchain Technology (BCT) has been explored and investigated. First, the information exchange processes in New Zealand were mapped based on the CIC Design Guidelines, and critical design information exchange transactions were identified as integration points for BCT. Next, a Decentralised Application (DApp) prototype system was designed to demonstrate and evaluate the proposed BCT integrated process models. Finally, the prototype system was evaluated by implementing it on simulated project processes and dispute scenarios.

An improved version of PIER BIM was developed to test the feasibility of blockchain-integrated information systems to record data from an actual construction project, analyse the costs of adding transactions on a public blockchain and assess the benefits of blockchain-based records in actual project dispute scenarios. A pilot study was conducted on data from a case study construction project to demonstrate the feasibility and analyse the transaction costs. Next, we inspected the applicability of blockchain-based records to information-related issues observed in legal cases in the past. The research output for this, a journal article, is currently under review.
