Abstract

Urgent global mandates for net-zero carbon emissions have escalated the focus on sustainable construction practices within the AEC industry. This research, therefore, seeks to investigate the integration of Big Data and Building Information Modelling (BIM) technologies to improve carbon accounting practices for prefabricated buildings. These are pivotal in reducing embodied carbon. It is aimed at the development of a comprehensive BIM that houses fundamental building data but integrates layers of information critical for effective decision-making processes.
This dissertation has identified a major gap in research in practical guidance and application for the integration of Big Data with BIM, thus fulfilling the lack of frameworks combining the two technologies effectively for enhanced environmental sustainability in construction. The present study is based on mixed-methods research, combining the literature review, empirical data collection, and a questionnaire survey to validate a new theoretical framework called the Integrative Digital Blueprint for Sustainable Construction (IDB-SC). In simple, it operationalizes the framework for carbon accounting within BIM processes and aims to put forth how advanced digital tools can drive efficiencies, reduce carbon footprints, and assist sustainable construction practices. The IDB-SC framework is thus positioned as a pivotal advancement, even for the construction industry, proving how digital innovation could change environmental and regulatory practices. However, the adoption of such technologies is hindered by existing limitations in the workflows and preparedness of the industry to adopt new technologies.
The key findings are related to the integration of Big Data and BIM, which revealed improvement not only in the accuracy of carbon accounting but also in sustainability and project management in general. However, continued or emerging challenges would include technological interoperability gaps, and further need for comprehensive training and policy support to stress continual adaptation and innovation of practices in this sector. The study brings to light the revolutionary potential that comes with the integration of big data with BIM technologies toward sustainability targets and advocates for continued improvement and empirical research activities that will further refine and optimize these integrative strategies.
