A Framework for Assembling Asset Information Models (aims) Through Permissioned Blockchain

There is a lack of accurate and valid data provision during the construction project lifecycle, and throughout the in-use phase of building assets. Construction needs to adopt a new technology to support building assets. Due to the current limitation of construction technology, Blockchain can be considered a new revolution within the most advanced construction applications. This paper proposes a framework for assembling Asset Information Models (AIMs) through private Blockchain to allow the owners, consultants, contractors, and suppliers to upload and visualise the data anywhere at any time throughout the lifecycle of the building to support project owners in making decisions. This paper introduces a conceptual framework through the processes of data analysis between the construction stages. The framework will improve current management efficiency in many ways such as: model upload/download, lack of data, partial model exchange, clash detection, conflict resolution, multiple data model formats, and data security. This helps project owners and maintenance teams to enhance their decision-making processes and improve the trust between stakeholders.
