Digital twin (DT) is gaining increasing attention due to its ability to present digital replicas of existing assets, processes and systems. DT can integrate artificial intelligence, machine learning, and data analytics to create real-time simulation models. These models learn and update from multiple data sources to predict their physical counterparts’ current and future conditions. This has promoted its relevance in various industries, including the construction industry (CI). However, recognising the existence of a distinct set of factors driving its adoption has not been established. Therefore, this study aims to identify the drivers and integrate them into a classification framework to enhance its understanding. Utilising popular databases, including Scopus, Web of Science, and ScienceDirect, a systematic literature review of 58 relevant DT adoptions in the CI research was conducted. From the review, the drivers for DT adoption in the CI were identified and classified. The results show that developed countries such as the UK, US, Australia, and Italy have been the top countries in advancing DT adoption in the CI, while developing countries have made commendable contributions. A conceptual framework has been developed to enhance the successful adoption of DT in the CI based on 50 identified drivers. The major categories of the framework include concept-oriented drivers, production-driven drivers, operational success drivers, and preservation-driven drivers. The developed framework serves as a guide to propel DT adoption in the CI. Furthermore, this study contributes to the body of knowledge about DT adoption drivers, which is essential for DT promotion in the CI.

Digital twin (DT) has gained significant recognition among researchers due to its potential across industries. With the prime goal of solving numerous challenges confronting the construction industry (CI), DT in recent years has witnessed several applications in the CI. Hence, researchers have been advocating for DT adoption to tackle the challenges of the CI. Notwithstanding, a distinguishable set of barriers that oppose the adoption of DT in the CI has not been determined. Therefore, this paper identifies the barriers and incorporates them into a classified framework to enhance the roadmap for adopting DT in the CI. This research conducts an extensive review of the literature and analyses the barriers whilst integrating the science mapping technique. Using Scopus, ScienceDirect, and Web of Science databases, 154 related bibliographic records were identified and analysed using science mapping, while 40 carefully selected relevant publications were systematically reviewed. From the review, the top five barriers identified include low level of knowledge, low level of technology acceptance, lack of clear DT value propositions, project complexities, and static nature of building data. The results show that the UK, China, the USA, and Germany are the countries spearheading the DT adoption in the CI, while only a small number of institutions from Australia, the UK, Algeria, and Greece have established institutional collaborations for DT research. A conceptual framework was developed on the basis of 30 identified barriers to support the DT adoption roadmap. The main categories of the framework comprise stakeholder-oriented, industry-related, construction-enterprise-related, and technology-related barriers. The identified barriers and the framework will guide and broaden the knowledge of DT, which is critical for successful adoption in the construction industry.

Purpose: The construction industry plays an important role in the achievement of the 11th and 15th of the Sustainable Development Goals. Efforts have been made by most developing and developed economies toward the achievement of these goals. Despite the efforts being made by the construction industry toward the achievement of these goals, there are still barriers that prevent built environment consultants from advancing environmental sustainability (ES) of construction projects. The purpose of this paper is to identify barriers to ES of construction projects. Design/methodology/approach: An extensive literature review on barriers to the adoption of ES was conducted and face-to-face semi-structured interviews of purposively selected built environment consultants in Ghana were carried out. Thematic template analysis of qualitative data was conducted. Findings: The key findings from the study include perceived initial costs, lack of knowledge on ES, technological difficulties, external pressures in adopting ES practices and environmental conditions in developing countries. Originality/value: The outputs of this study offer strategies which are very significant to the construction industry in embracing ES. Further, the findings contribute to knowledge on achieving the sustainable development agenda.

The COVID-19 pandemic has brought massive online activities and increased cybersecurity incidents and cybercrime. As a result of this, the cyber reputation of organisations has also received increased scrutiny and global attention. Due to increased cybercrime, reputation displaying a more important role within risk management frameworks both within public and private institutions is vital. This study identifies key factors in determining reputational damage to public and private sector institutions through cyberattacks. Researchers conducted an extensive review of the literature, which addresses factors relating to risk management of reputation post-cyber breach. The study identified 42 potential factors, which were then classified using the STAR model. This model is an organisational design framework and was suitable due to its alignment with organisations. A qualitative study using semi-structured and structured questions was conducted with purposively selected cybersecurity experts in both public and private sector institutions. Data obtained from the expert forum were analysed using thematic analysis, which revealed that a commonly accepted definition for cyber reputation was lacking despite the growing use of the term “online reputation”. In addition, the structured questions data were analysed using relative importance index rankings. The analysis results revealed significant factors in determining reputational damage due to cyberattacks, as well as highlighting reputation factor discrepancies between private and public institutions. Theoretically, this study contributes to the body of knowledge relating to cybersecurity of organisations. Practically, this research is expected to aid organisations to properly position themselves to meet cyber incidents and become more competitive in the post-COVID-19 era.

Lack of deliberations on the environment regarding its designing, utilization, development as well as effective management of the natural environment has led to its pollution. This leaves a lot to be desired especially in most developing countries which are now embracing environmental sustainability. This paper examines the drivers of environmental sustainability of construction projects. A qualitative study using semi-structured interviews was conducted with purposively selected built environment consultants in Ghana within a case study (The Kumasi City Mall project). Thematic template analysis revealed designer’s own philosophy, request by clients, incentives for green designs, policies and regulation, and competitive advantage as the drivers of environmental sustainability of construction projects. Furthermore, the results disclosed specific governmental role and social network utilization as drivers of environmental sustainability of construction projects. The outputs of this study offer strategies which are significant to the construction industry in embracing environmental sustainability. Further, the findings contribute to knowledge on achieving the sustainable development agenda.
