Digital-enabled Design for Manufacture and Assembly (DfMA) in offsite construction: A modularity perspective for the product and process integration


This study aims to use modularity to impact various facets of Design for Manufacture and Assembly (DfMA) and explore the relationship between product modularity, process modularity, and DfMA within the context of Offsite Construction (OSC). The study fills this gap through an exploratory single case study by identifying perceptual measures of these three concepts. The study shows the alignment between multi-dimensionality of modularity, such as product modularity and process modularity, enhances the capability of DfMA. From a modularity perspective, the reconfiguration of abstraction, information hiding, and interface is an essential strategy to change the traditional design process. This reconfiguration is to adapt to the new scenarios brought by OSC and digital fabrication technologies and the new design tasks associated with these scenarios. This study has theoretical implications for the modular approach to DfMA and practical implications for those who expect digital fabrication techniques in offsite construction.
