Abstract
For many types of projects, modular integrated construction (MiC) is increasingly becoming a preferred method of construction. However, MiC projects are associated with unique risk factors different from those of the traditional construction projects. Thus, it is imperative to conduct a bespoke assessment of the risk factors for MiC projects. This research modelled 29 critical risk factors (CRFs) associated with MiC projects. Quantitative data on the relative significance of CRFs were collected from international MiC experts using structured questionnaires. A principal component analysis generated 4 principal risk factors (PRFs) for MiC projects comprising stakeholder and supply chain risks, design and capabilities risks, financing risks, and regulatory risks. A fuzzy synthetic modelling of the CRFs revealed that the 4 PRFs were significant but with varied impact on MiC projects. This research constitutes the first exclusive quantitative modelling of MiC risk factors with useful practical and theoretical implications. Practically, the research has identified and prioritized the CRFs associated with MiC projects and may serve as a risk evaluation decision support in MiC project planning and implementation. Theoretically, the results contribute to the checklists of CRFs for MiC projects which may form the basis for future studies on the risks of MiC projects.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
