Businesses in the construction industry are experiencing pressure to modernize by embracing digital technologies. Like any other change initiative, digital transformation requires that leaders are at the forefront of their organizations’ pursuit for digital innovation. Therefore, the purpose of this study was to explore the different leadership approaches exhibited by construction industry leaders in influencing their organizations’ digital paths. Qualitative data collected from 41 construction industry professionals were analysed using an inductive thematic analysis approach. The main finding was a taxonomy of digital leadership types characterized under six themes: proactive and forward-thinking; supportive; uncoordinated; cautious; resistant and visionless and undriven leaders. These themes provide an insight into how leaders influence the digital transformation paths in organizations. As far as the authors are aware, this study is the first that developed a taxonomy of digital leadership approaches in the construction industry. This is a valuable step in understanding leaders’ influence in driving digital transformation in the construction industry. Thus, the taxonomy of digital leadership can be used to evaluate leadership styles and attitude towards digitalization. The findings are also a platform for further studies on digital leadership in construction.

Zambia, and Sub-Sahara Africa (SSA) generally, is lagging behind in the area of sustainable construction due to several barriers to the implementation of sustainable construction. This study therefore explored drivers and barriers to the adoption of sustainable construction practices in Zambia. The study could inform stakeholders on measures which could improve the implementation of sustainable construction. The study used an online quantitative questionnaire survey of construction professionals and clients. A total of 112 responses were received representing various stakeholder groups in the construction industry. The data were subjected to factor analysis and ranked using the relative importance index. The data show that drivers to sustainable construction cluster into three constructs namely, environment and health-related factors, regulatory and industry-related factors and, economy and firm-related factors. Barriers clustered into three groups namely, awareness and knowledge-related factors, regulatory and industry-related factors and, economy and cost-related factors. Therefore, measures aimed at improving sustainable construction in Zambia should focus attention on these broad clusters.

Purpose: This study examined the factors that influence households’ intention to adopt solar energy solutions in Zambia. This, in view of low adoption rates of solar energy solutions even in the wake of a widespread electricity power generation deficit across sub-Sahara Africa (SSA) has plagued the region with daily electricity load shedding lasting several hours at a time. Given the vast potential for solar energy generation in the region, solar energy solutions have become an attractive option to grid-based electricity, and many households have intentions of adopting these solutions.Design/methodology/approach: Through the lens of the theory of planned behaviour (TPB), the study surveyed adult household members in Zambia who contributed towards the household’s income. The participants were selected using the snowballing technique, which yielded a sample of 961 respondents. The results were analysed using structural equation modelling.Findings: The results show that attitude, trust, benefits and subjective norms influence the intention to adopt solar energy solutions. Trust and benefits also influence the intention to adopt solar energy solutions indirectly through attitude. Therefore, measures aimed at increasing the adoption of solar energy solutions should focus on improving the attitude, perceived benefits, trust in the solutions and consider subjective norms.Originality/value: The findings add to the understanding of the factors that influence the intention to adopt solar energy solutions in Zambia. Therefore, the findings can be used to inform measures aimed at improving solar energy uptake in Zambia. The study also reports on the previously unreported mediating role of attitude towards solar energy solution on the associations between perceived benefits and trust with solar energy solutions adoption intention.

Purpose: Amidst all solutions posited to address sustainable construction practices in Nigeria, the implementation plans are repudiated by sustainable barriers. This study examines and confirms the strategy with the most significant impacts on the identified barrier to sustainable construction practice (SCP).Design/methodology/approach: The study deployed a questionnaire survey to evaluate the perspective of 100 construction actors on the barriers and strategies of sustainable construction practice in Nigeria. Factor Analysis was employed to categorize key barriers and strategies into their underlying clusters for further analysis. Partial least squares-structural equation modelling (PLS-SEM) was used to confirm the construct's significant relationship and magnitude, thereby establishing the strategies with the highest impacts on the barriers to sustainable construction practices.Findings: The findings revealed three clusters of barriers and four groups of strategies to SCP, including technopolitic barrier, perception and awareness barrier and sociocultural barrier. For the significant strategies, education and training, stakeholder regulation, incentive support and government and legislative support strategies were established. Overall, education and training strategy was identified as the most dominant and effective strategy to mitigate the barriers of SCP in Nigeria.Originality/value: The paper establishes education and training as the key strategy to achieving sustainable quest in the AEC industry. The practical implication is that policymakers, educators and professional bodies can harness sustainable knowledge transfer through education and training to improve sustainable construction practices in Nigeria.

The shift towards digitalisation has been empowering growth in the construction industry, especially in the past decade. Construction stakeholders are offered myriad benefits by embracing digital advancements to achieve efficiency. However, the exploitation of digital opportunities is bounded by the need for a practitioner skillset that aligns with the digital era, a requirement that has been described as difficult to meet and justified by the low degree of digital literacy among construction employees. This paper reports findings from interviews with 19 leaders and decision makers in the construction sector to reveal the indicators that can predict construction employees’ digital literacy. Such an approach offers a comprehensive exploration of the likelihood of employees’ digital literacy through socially oriented characteristics. Overall, 19 individual characteristics emerged from the thematic analysis and highlight the critical connection between social behaviour and digital literacy. The findings of this paper are timely and important for those businesses assessing their employees’ willingness and maturity with regard to technological change through social and behavioural information. The qualitative approach led to the development of a conceptual framework that can explain the dynamics needed to assess employees’ digital literacy in construction organisations. This study, therefore, reveals the effectiveness of predicting employees’ readiness to shine in the digital era by shedding light on their digital literacy through examinations of individual characteristics in a construction workplace. This paper is among the first to encourage research efforts that take into account the importance of studying social and psychological complexities, which are subject areas that are limited in recent construction literature. As such, it is of value to employers wishing to embed greater digitalisation in their firms, as well as researchers in this domain and policymakers looking to encourage greater digital transformations.

The construction industry is constantly evolving through government policies, technologies, and innovative processes. BIM and modular construction are innovative concepts aimed at achieving sustainable smart cities by enhancing cost performance, efficiency, and sustainability. Despite growing global interest in their integration, there is a notable knowledge gap in sub-Saharan Africa. As a result, this research aims to explore the barriers to integrating BIM into modular construction in sub-Saharan Africa. The study adopted a non-experimental design, using a four-stage methodological framework. Initially, a literature review was carried out to conceptualize the study. Stage two involves a pilot survey to create an adequate data collection instrument. In the third stage, 81 registered companies were purposely selected, and data was collected through an online survey. Finally, the fourth stage uses descriptive and inferential techniques to make logical and informed conclusions. The top-ranked barriers are high initial costs, insufficient cross-field expertise, stakeholder collaboration problems, limited software interoperability, and skills shortages. Recommendations include early stakeholder collaboration, BIM execution plan development by modular companies, improved staff training, and increasing financial support from the government. Future research should explore country-specific barriers and case studies to aid the integration of the two innovative solutions in the region.
