The adoption of emerging technologies is critical to enhance construction industry performance. Previous studies have shown that the Nigerian construction industry (NCI) is slow to adopt digital technologies and faces performance issues. As a result, this study aims to investigate and model the barriers to adopting digital twin (DT) technology in the NCI with the view to provide stakeholders with adequate information on the multifaceted nature of DT barriers and provide strategies to improve DT adoption.

The study adopts a qualitative and quantitative approach to achieve the overall aim of the study. The qualitative approach included a scoping review used to identify barriers to DT adoption from the literature. A five-point Likert scale questionnaire was administered to 246 construction professionals in the NCI. This was followed by critical analysis using mean ranking and standard deviation, Kruskal–Wallis, factor analysis and partial least squares structural equation modelling (PLS-SEM).

The exploratory factor analysis revealed four categories of barriers to DT adoption in the NCI: “technological and investment”, “data management and government”, “project and human resources” and “digital transformation”. The PLS-SEM results revealed the causal relationships of four barriers categories and their concomitant effects on DT adoption in the NCI. The top three barrier categories that require critical attention in order of significance are: technological and investment (ß = 0.655), data management and government (ß = 0.313) and project and human resources (ß = 0.194). Digital transformation (ß = −0.046) has the least significance. Overall, all the barriers’ categories were accepted at a significance level of p < 0.05.

The practical implications include guiding policymakers and practitioners in making informed decisions to address the identified barriers to DT adoption in the NCI. The findings may also be applicable to other developing countries in Africa and beyond. By implementing effective policies and stakeholder guidelines, the NCI can advance technologically and enhance its competitiveness to execute advanced construction projects.

This research contributes to the construction industry by shedding light on the barriers to DT adoption and their intricate interconnections within the NCI context. It is also the first study in NCI context to present the level of DT awareness and explore the concomitant effects of the barriers.

This study examines the barriers impeding the implementation of circular economy (CE) practices in the Nigerian architecture, engineering, construction and operation (AECO) industry across diverse regions of Nigeria.

The study adopts a quantitative approach using a five-Likert scale questionnaire (Google Forms), utilizing various analytical tools, encompassing descriptive and inferential statistics. This methodological approach allows for a multifaceted exploration of the intricacies surrounding the barriers to circular CE.

The study identifies and examines 24 CE barriers which are determined to be significant to the implementation of CE. These barriers were categorized into four categories: “Economic”, “Market and Information”, “Policy and Operational” and “ product development”.

The adopted sampling technique may restrict the generalizability of the findings within and beyond the selected regions. Furthermore, while the analytical methods offer a comprehensive analysis, they may not capture the nuanced intricacies that qualitative methodology could provide. However, the findings can be applied to other developing countries with characteristics similar to those of the Nigerian construction industry.

The study’s findings are significant for stakeholders such as policymakers, industry and academia. By elucidating CE-specific barriers, the research facilitates the formulation of targeted and tailored strategies, fostering the integration of CE principles in the Nigerian construction industry.

This study presents novel insights into the barriers hindering the implementation of CE in the Nigerian construction industry. Offering tailored strategies and categorizing barriers into clusters adds a unique perspective to CE literature, particularly in developing countries.

This study aims to investigate the drivers influencing the implementation of circular economy principles in the Nigerian architecture, engineering, construction and operation (AECO) industry across diverse regions of Nigeria.

A quantitative research approach was adopted, using a structured questionnaire distributed to AECO professionals across four selected regions (North Central, North West, South-South and South West) in Nigeria. The data were analysed using Kruskal–Wallis test and structural equation modelling (SEM).

The study findings show a robust consensus of opinions among the respondents across regions and professions. The SEM analysis establishes the significant influence of the hypothesized drivers, regulatory and institutional, supply chain collaboration, technological advancements, organizational support and business strategies on the successful implementation of circular economy principles in the Nigerian AECO industry.

The study is limited to specific regions and professions within Nigeria. Further limitation is the quantitative orientation of this study, which collects data using only a questionnaire.

The findings imply that stakeholders can adopt a unified approach to promote circular economy principles in the AECO industry. By recognizing the common understanding of circular economy drivers, collaborative efforts can be streamlined to advance sustainability, resource efficiency and circularity in the industry.

This study contributes to the nascent field of circular economy implementation in the Nigerian AECO industry. It offers a unique perspective by exploring variations in stakeholder opinions, providing insights into the nuanced understanding of circular economy drivers.
