Abstract
Purpose
This study aims to explore the relationship between three primary constructs: leadership styles, job satisfaction and organizational commitment among private-practice quantity surveyors in the Nigerian construction industry.
Design/methodology/approach
A questionnaire survey of 127 quantity surveying consultancy firms in Abuja was conducted using a quantitative research approach. A total of 76 acceptable questionnaires were returned from a total of 127 that were distributed, giving a response rate of approximately 60%. The data were analyzed using partial least square structural equation modelling.
Findings
Results showed a positive indirect link between leadership styles and organizational commitments, with job satisfaction acting as a partial mediator. It was also found through importance–performance map analysis, which is crucial for prioritizing managerial actions, that an employee’s commitment to a task is strongly influenced by that person’s level of job satisfaction.
Research limitations/implications
The study is quantitative and cross-sectional in nature, collecting information from a single source within an organization. A longitudinal strategy and a mixed methods approach should be used in future research.
Practical implications
Superiors/principal partners should make an effort to demonstrate a comprehensive understanding of leadership styles that is capable of enhancing job satisfaction and creating pleasant interaction in the work environment to increase the commitment of employees working in quantity surveying consultancy businesses.
Originality/value
As far as the author is aware, this study is one of the few to examine the impact of job satisfaction as a mediator between organizational commitments and leadership styles in the Nigerian construction industry. Furthermore, the study provides the basis for further discussion of the concepts offered in the paper.

Abstract
Purpose
The architecture, engineering and construction (AEC) industry is currently undergoing a paradigm shift as it integrates innovations such as digital twins (DT) in its activities. As a result, this study aims to ascertain the barriers affecting the implementation of digital twin (DT) technology in Nigeria’s AEC sector.
Design/methodology/approach
The study employed a quantitative approach using a questionnaire distributed via Google Forms, yielding 120 valid responses from built environment professionals in Nigeria. The data were subjected to statistical tests such as the Kolmogorov–Smirnov test, Cronbach’s alpha, descriptive statistics and the Kruskal–Wallis test. Hypotheses were validated through partial least squares structural equation modelling (PLS-SEM).
Findings
The study revealed that out of the 43 identified barriers, inadequate system integration, challenges in guaranteeing interoperability, university education on the subject is deficient, and new system compatibility with legacy systems are the main barriers to implementing DT for sustainable construction practices in the AEC Industry of Nigeria.
Research limitations/implications
The study was conducted in Nigeria with a focus on the Federal Capital Territory. The study identified the barriers of DT in the construction sector.
Practical implications
This study developed and assessed a theoretical framework, examining the relationships between variables. The findings have important implications for the construction industry, offering opportunities to improve construction processes. Furthermore, the study will help improve sustainable practices within the built environment.
Originality/value
The study categorised the barriers of DT into the following: system integration; security-related; performance-related; organizational-related; data quality issues and environmental related issues.

This paper evaluates the benefits of harnessing artificial intelligence (AI) tools for safety compliance on construction projects in Nigeria.
Abstract
Purpose
This paper evaluates the benefits of harnessing artificial intelligence (AI) tools for safety compliance on construction projects in Nigeria.
Design/methodology/approach
This study employed a specialised approach by combining qualitative and quantitative approach. The study carried out a brief systematic literature review (SLR) to identify the variables of the study. These variables were prepared in a questionnaire which was distributed among professionals within the Nigerian construction sector using purposive sampling. A total of 140 questionnaires were retrieved. The collected data were analysed using Relative Importance Index (RII), Ginni’s Mean (GM) and exploratory factor analysis (EFA).
Findings
The analysis revealed that all the identified benefits hold considerable importance, with an average RII of 0.86, with real-time monitoring as the most prominent advantage. However, using the GM which was 0.861, the study identified “mitigation of hazards on worksites” as the stationary benefit of AI in safety compliance.
Research limitations/implications
The study was conducted exclusively within Nigeria’s Federal Capital Territory, using a cross-sectional survey approach.
Practical implications
The results will be valuable for professionals and practitioners in the Nigerian construction sector, as they will acquire insights into the potential advantages of utilising AI tools for monitoring of safety compliance on construction projects.
Originality/value
The study adopted a robust approach by identifying the stationary benefit using the GM in combination with RII and EFA.
