BIM in the Malaysian construction industry: a scientometric review and case study
Purpose – The purpose of this study is to explore existing literature on Building Information Modelling (BIM)
in Malaysia and examine the perception of practitioners about the potential of BIM applications in reducing
construction waste and enhancing productivity.
Design/methodology/approach – First, using 244 bibliographic data extracted from the Scopus database,
the paper used scientometric analysis and VOSviewer mapping technique to assess the most impactful
publication literature on BIM in Malaysia to identify the existing research gaps. Second, using a structured
questionnaire, a total of 100 questionnaires were distributed to practising practitioners who incorporate BIM in
the delivery of their projects. Descriptive analysis using cross-tabulation in SPSS software, radar chart, relative
importance index and Pearson’s correlation were used to analyze the data.
Findings – The research gaps are in the fields of construction projects, buildings, energy efficiency, lifecycle
and housing. The findings of the survey indicate that quantity take-off, clash detection, site utilization
planning, digital fabrication as well as 4D stimulation were the main BIM applications used among the
practitioners in Johor and Selangor.
Practical implications – By assessing the state-of-the-art of BIM and BIM applications in this region, the
practical implications of this study provide useful insights to construction stakeholders, funding organizations,
policymakers, research institutions, professionals, journal editors, reviewers and researchers to understand the
overall trend of BIM in Malaysia and its usage.
Originality/value – This paper is the first to use science mapping using scientometrics to reveal the current
BIM research in “Malaysia only”. Relying on the identified gaps, the study further examined the usage of BIM
applications in Malaysian construction projects

Bibliometric analysis, scientometrics and metasynthesis of Internet of Things (IoT) in smart buildings
Purpose: The Internet of Things has made the shift to the digital era possible, even though the Architecture, Engineering, and Construction (AEC) sector has not embraced nor integrated it within the core functions compared to other sectors. The need to enhance sustainable construction with the adoption of Internet of Things in this sector cannot be overemphasized. However, the real-world applications of Internet of Things in smart buildings remain relatively unexplored in the AEC sector due to several issues related to deployment and energy-saving potentials. Given these challenges, this paper proposes to identify the present state of development and research in Internet of Things and smart buildings, and identify Internet of Things clusters and applications in smart buildings.
Design/methodology/approach: Bibliometric analyses of papers from 2010 to 2023 using the Scopus database and scientometric evaluations using the VosViewer software were undertaken. The proper search keyword was identified by using the phrases “ Internet of Things” and “Smart Building”. A total of 1158 documents in all, written by 3540 different writers, representing 2285 different institutions from 97 different countries were looked at. A metasynthesis was conducted and a system of Internet of Things applications in a smart building is illustrated.
Findings: The development of IoT and Smart Buildings is done in two phases: initiation (2010-2012) and development (2013-2023). The IoT clusters comprised internet of things, energy efficiency, intelligent buildings, smart buildings, and automation; while the most commonly used applications were analysed and established. The study also determined the productive journals, documents, authors, and countries.
Research limitations/implications: Documents published in the Scopus database from 2010 to 2023 were considered for the bibliometric analysis. Journal articles, conference papers, reviews, books, and book chapters written in English language represent the inclusion criteria, while articles in press, conference reviews, letters, editorials, undefined sources, and all medical and health publications were excluded.
Practical implications: The results of this study will be used by construction stakeholders and policymakers to identify key themes and applications in IoT-enabled smart buildings and to guide future research in the policymaking process of asset management.
Originality/value: The study utilised bibliometric analysis, scientometrics and metasynthesis to investigate internet of things applications in smart buildings. The study identified internet of things clusters and applications for smart building design and construction.
Keywords: Artificial intelligence, bibliometrics, internet of things, network sensors, smart buildings
A scientometric review of geopolymer concrete
The drive towards sustainable construction materials that will reduce the amount of CO2 produced during the manufacture of Portland cement has led researchers to investigate the suitability of alternative materials in concrete production. The use of industrial and agricultural by-products such as fly ash, slag, rice husk ash, and natural pozzolanas high in aluminosilicate content have been found useful in the production of geopolymer concrete which has become a suitable replacement for OPC concrete with its higher strength, temperature stability, denser microstructure, higher bond strength, and resistance to chemicals. A holistic approach for the first scientometric review on geopolymer concrete is described in this study. The study embraced an all-inclusive review concept using scientometric analysis and science mapping technology, and comprehensive discussion to highlight the most influential publication sources, most used keywords, most active researchers and institutions, as well as literature with the highest impact on the field of Geopolymer concrete; to examine the current state-of-the-art research focus, and to identify the current research gaps. The study analyzed 2011 related bibliographic data mined from the Scopus database. The research gaps identified were in the areas of geopolymer type, materials, mix design, mechanical properties, durability properties, microstructure, and adoption and application. Further long-term studies are required in these areas to provide a basis for a regulatory framework for adoption of geopolymer concrete. This study will help researchers understand the current trend in geopolymer concrete, opening more room for further research as well as serve as a source of information for policy makers, journal editors, professionals and research institutions
