    Dynamic supply chain capability analysis of Hong Kong-Zhuhai-Macao bridge construction: a topic modeling approach
    (2021-07) Ekanayake, EMAC; Shen, GQ; Kumaraswamy, MM; Xue, J
    Prefabricated construction as a preferred construction approach instigated significant technological advancements in construction supply chains in Hong Kong (HK). The Hong Kong-Zhuhai-Macao Bridge (HZMB) was a milestone prefabricated construction project which was successfully constructed using these industrial advancements. However, the project itself was a great challenge as it was highly vulnerable to disruptions due to complex supply chain processes. In this regard, increased resilience could be the key to boosting project performance through enhanced Supply Chain Capabilities (SCCs), where identifying SCC dynamics becomes essential. Therefore, this study employed the Topic Over Time Modeling approach to detect critical SCCs using 1,748 unstructured official documents on the HZMB from 2003 to 2018, which spans the period from project design to handover. The popularity trend analysis of texts enabled identifying the six most critical capabilities associated with each construction phase of planning, construction and handover. Thereafter, an ex-post capability evaluation map was developed by considering the popularity trend of capabilities and their relevance to different project phases. Industry practitioners would benefit from prior knowledge of SCCs and their dynamic impact on each project phase to prioritize initiating them adequately and appropriately, targeting value-enhanced-resilient supply chains in ex-ante decision-making of future prefabricated infrastructure development projects. Further, the text-mining research approach unveils to academia, an effective and novel mechanism to extract dynamic empirical clues from

    Smart retrofitting for existing buildings
    (Elsevier, 2023) Peiris, S; Lai, JHK; Kumaraswamy, MM; Hou, H
    Transforming ordinary buildings into smart building (SB)s, considered as ‘smart retrofitting (SR)’, requires retrofit works that involve smart technology applications. Given the limited knowledge about the SR concept, a systematic literature review was conducted using a mixed methods approach. Following the ‘Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)’ framework, which is a well-recognized comprehensive reporting guideline for systematic reviews, SR-related literature was first identified from ‘Scopus’ and ‘Web of Science’. A bibliometric analysis of the identified literature revealed that the past research predominantly focused on energy efficiency and occupant comfort while social and legal issues were underexplored. A further, qualitative review of the shortlisted literature unveiled the SR research gaps and six future research areas: (1) smart retrofit performance evaluation, (2) SR applications for building envelope optimization, (3) renewable energy integration through SR applications, (4) SR applications for demand side management, (5) stakeholder engagement in SR, and (6) planning for effective SR implementation. Outcomes synthesized from this study include a framework consolidating the review findings and a mapping exhibiting the nexus of future research directions, which serve to facilitate and catalyze expected efforts for realizing SBs.
