Abstract: Successful projects in construction project management are those that can meet contractual obligations, including quality standards, and are finished on time and within budget. In addition, sustainable construction and low productivity have been in great concern, and they are used as indicators to review how successful the project could be or alert stakeholders of problems throughout all of the project phases. Higher productivity and less waste generated mitigates the risk of project delay and losses. To enhance the efficiency of construction projects, information technology is the key. The manufacturing industry cannot be excluded as they are related to many upstream production processes in construction projects. For example, most of the building materials are rarely raw and need fabrication in manufacturing plant before delivering to construction sites.
Additionally, Industry 4.0 enhances the development of smart manufacturing. Its key is the digital transformation of the entire industry. As a result, the transformation relies on how new and existing technologies are adopted during the transition. With the availability of reliable data and information, its success will have a favourable impact on the construction industry. Therefore, prefabrication at the manufacturing plants can be expanded upon in the construction industry. Actually, prefabrication has been adopted for decades in the construction industry and is mainly applied in the public housing development at present. It has been increasingly implemented as a solution to enhance productivity and quality control, reduce waste generation and alleviate associated negative impacts on environment, hence achieving sustainability.
There is currently a research gap in the total digital transformation of the prefabrication supply chain in Hong Kong, particularly in terms of the use of digital technology across the entire supply chain. To meet the current issues encountered by various stakeholders, this research intends to investigate how the construction sector in Hong Kong is implementing digital technology. The thesis focuses on the supply chain of prefabricated construction employing prefabricated curtain wall as the chosen building component and incorporates digital technology associated with Industry 4.0. It also helps to advise on the most appropriate use of both standalone and integrated digital technology to address existing problems.
Overall, the study contributes to promote prefabricated building components more effectively and comprehensively with feedback of multi-stakeholders. The study's findings also help to narrow the knowledge gap regarding client satisfaction for prefabricated products from both individual and collaborative perspectives, which serves as the direction for the advancement of construction technology and management. In order to accurately characterise the beneficial digital technologies, the rankings of the multi-stakeholders' preferences for digital technologies as well as their contributions to various challenges were revealed. The recommended integrations were practical, giving industry participants a clear point of reference.
