Building information modelling for construction productivity measurement
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Archchana, S; Pan, W
Productivity is a critical performance indicator of the construction industry, and thus warrants effective and efficient construction productivity measurement (CPM). Building information modelling (BIM), a digital representation of the building process, plays a significant role in effective and efficient CPM. Considering the high mandatory requirements for enhancement in construction productivity measurement, this paper aims to review the state-of-the-art literature on BIM-integrated CPM, to identify gaps in the existing body of knowledge and explore future research trends. The aim is achieved through a systematic literature review and bibliometric analysis where the data are retrieved from Web of Science, Scopus, and Google Scholar and proposes future research directions. In total 260 publications were identified from the initial search, and 56 were shortlisted for full-text analysis after several levels of screening including duplication, title and abstract checking. Finally, 21 were narrowed yielded for detailed review for this study. The results mapped the yearly publication trend, publications by source and the co-occurrence of terms. The findings help to identify a suite of BIM-integrated CPM methods used in the construction industry and provide a foundation for future research in CPM. A framework is developed to illustrate the knowledge gap and future directions identified in this study. Accordingly, the findings revealed that existing studies on utilising BIM for CPM are limited to only 3D and 4D BIM. Further, there is a lack of studies on the feasibility of using BIM for CPM, fully automated BIM integrated CPM tools and real-time CPM through BIM.

Mapping and improving sustainable construction management through social network analysis: a review
Madhusanka, N; Pan, W; Kumaraswamy, M
Social Network Analysis (SNA) has been used in multidisciplinary research during the past two decades due to the unique nature of network visualisation and extensive analytical capabilities. This tool has also gained increasing attention among the researchers in the sustainable construction arena in recent years. Nevertheless, a thorough review has not yet been done to review the application of SNA in the sector of sustainable construction. This paper attempts to address this gap through a comprehensive review of previous journal publications. Accordingly, 73 journal papers were initially identified for review through the “Web of Science “publications database. Subsequently, a bibliometric analysis was done through “VOS viewer” software package to identify the research trends throughout the past years. The results show significant progress in relevant publications during 2014-2018 and a major contribution to research from China. After an extensive filtration process, 17 particularly relevant journal papers were identified which have applied both social network visualisation and analysis techniques for the sustainability aspects of construction. The contents of these papers were comprehensively analysed in terms of data collection methods, network analysis techniques, network structures and sustainability knowledge areas. Finally, this paper contributes to theoretical knowledge in this domain, by suggesting a future research direction through a SNA conceptual model to analyse stakeholder collaborations for project life cycle sustainability initiatives. The findings of this paper will serve as a good source for future researchers to comprehensively identify, compare and contrast the applications of SNA techniques for sustainability related studies in the construction sector.
