Modularization Considerations for Modular Integrated Construction in Hong Kong: A Case Study

Modularization has become an important strategy to support current enterprises in gaining an edge in a competitive market. The construction industry is also continuing to explore the same trend. Modular integrated construction (MiC) in Hong Kong is one of these notable examples. MiC has been vigorously promoted by the Hong Kong government as an innovative construction method. However, MiC has some features that make it challenging to adopt, e.g., a wider range of stakeholders and a longer supply chain compared to the traditional construction method. This means that the requirements of all parties and subsequent stages should be considered early in the design phase. Modularization, as a critical aspect of MiC design, should also be carefully carried out to achieve smooth construction. This study, therefore, adopts a case study method to explore the modularization considerations in a real-life MiC project in Hong Kong. Four major considerations are summarized, including design with repetitive module units, compact dimensions of module sizes, lightweight module units, and layout adjustment of the structural core. This study will contribute to the design theories and practices by providing evidence-based modularization considerations in modular building design.
