Abstract
The Hong Kong-Zhuhai-Macao Bridge (HZMB) was a challenging milestone construction project that boosted the Hong Kong construction industry participants to new heights of recognition. While industry-boosting long-term benefits arose from knowledge gained in managing specialist prefabrication processes and complex supply chains (SCs), these advances also necessarily imposed challenges, rendering the project highly vulnerable to disruptions. Therefore, higher resilience was essential to withstand higher Supply Chain Vulnerabilities (SCV) through enhanced capabilities, for which identifying dynamic SCV becomes critical. To address this, the study employed the Topic Over Time modelling approach to detect critical SCV using 1,748 unstructured official documents on the HZMB from 2003 to 2018 (project design to handover). The popularity trend analysis that was thereby conducted, enabled identifying the six most critical vulnerabilities and categorizing them among each project phase. Finally, an ex-post vulnerability evaluation map was developed by considering the vulnerabilities' popularity trend and their relevance towards the project and SC phases. Using these findings, industry practitioners could improve their ex-ante decision-making, targeting value-enhanced-resilient SCs in future prefabricated infrastructure development projects. Further, the text-mining research approach unveils an effective mechanism for researchers to extract dynamic empirical clues from a large unstructured set of documents in construction SCs

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
