    Diagnosing Government Responsibilities in the Implementation of Public-Private Partnership System for Infrastructure Procurement
    (International Journal of Sustainable Development and Planning Vol. 20, No. 6, 2025-06) Ojelabi, Rapheal A.; Oyenubi, Adebayo; Oyeyipo, Opeyemi
    Public-Private Procurement is a system that allows for collaboration between the government and private partners in infrastructure provision. However, researchers argued that the successful implementation of the procurement option rested more on the government's shoulders. Hence, the study aims to identify critical government roles and investigate their importance and performance in PPP projects in Nigeria using a survey approach. The targeted respondents are PPP stakeholders operating in Lagos and Abuja. However, due to the absence of comprehensive lists of the PPP stakeholders involved in PPP projects in Nigeria, a project based approach was used in attaining the representative samples for the study, including contractors, consultants, concessionaires, government agencies, and financiers. About 384 copies of questionnaires were randomly distributed to the sample representatives, and 274 copies were retrieved. The data generated were analyzed using descriptive and inferential statistical tools. Findings showed that all the roles identified are critical and showed significant interrelationships with each other. However, the government's performance in the highlighted roles is unsatisfactory, and recommendations were made on its shortfall.

    Adoption and Barriers of Engineered Bamboo Products in the Nigerian Construction Industry
    (Civil Engineering and Architecture 13(2), 2025) Ojelabi, Rapheal A.; Omuh, Ignatius O.; Amusan, Lekan M; Ogunrinde, Olugbenro
    The rise in the cost of conventional construction materials and the greenhouse effect from construction activities have been an issue of concern to stakeholders in the construction industry. Hence, efforts have been concentrated on developing low-cost, environmentally friendly and sustainable local materials to mitigate the greenhouse effect. The quest for the sustainable materials necessitates the study to examine the prospects of adoption of engineered bamboo products and the challenges militating against its use among construction professionals. A quantitative approach was adopted and 70 questionnaires were distributed among construction professionals with structural engineering background in selected firms across Lagos State. Data collected were processed using percentage, mean item score and Kruskal Wallis’s test. Facts garnered from the study revealed that engineered bamboo adoption for construction related works like ceiling, flooring, and reinforcement among others is not outstanding. The poor implementation of the engineered bamboo products is attributed to some challenges which include ‘high affinity for conventional materials’, ‘unavailability of bamboo products’ and ‘lack of machinery to refine raw bamboo’ among others. Therefore, the study recommends that stakeholders need to channel more resources into research and development and creating an enabling policy that can enhance the bamboo products adoption.

    Construction Craftspeople Apprenticeship in Nigeria: From the Lens of Apprentices
    (Routledge; Taylor & Francis, 2026) Tunji-Olayeni, Patience; Adah, Christiana Ada; Daniel, Emmanuel Itodo; Aghimien, Douglas
    The construction industry is facing a shortage of skilled workers worldwide. This shortfall can be addressed through the construction craftspeople apprenticeship system, which has not received significant attention in developing countries like Nigeria. This study aims to explore the experiences of apprentices in construction craftspeople apprenticeship programs in Nigeria. Data were collected using questionnaire surveys and interviews. Astructured questionnaire was distributed to thirty-two apprentices across two construction craftspeople apprentice ship programs in Nigeria, and sixteen interviews were conducted. The survey data were analyzed using the Relative Importance Index (RII), while data from the interview were analyzed using content analysis to identify key themes. The findings revealed that the primary motivators for individuals to pursue apprenticeships in the construction sector include the desire to work in the construction industry, the opportunity for skills and ability development, and the opportunity for income and associated benefits. Conversely, the major challenges faced by apprentices include limited job availability after completing their apprentice ship, poor or nonpayment of allowances, redundancy during training and inadequate training quality. These findings are significant for con struction stakeholders as they highlight the need for strategies to encourage young people to engage in apprenticeship training while addressing the challenges faced by apprentices.

    The experience of women in construction craftspeople apprenticeship programmes in Nigeria
    (Emerald Publishing Limited; ICE Publishing, 2025) Tunji-Olayeni, Patience; Adah, Christiana Ada; Daniel, Emmanuel Itodo
    The construction industry needs skilled personnel for its sustainability due to the shortage of skilled workers. Women are reputed to bridge the gap created by skills shortages in construction, which can be achieved by increasing their par ticipation in the industry through the instrumentality of construction craftspeople apprenticeship training. This qualita tive study explored the experiences of women in construction craftspeople apprenticeship programmes in Nigeria. Twelve female apprentices and two representatives of stakeholders (senior managers at the apprenticeship pro grammes) from two construction craftspeople apprenticeship programmes were interviewed on the factors that moti vated women to join construction crafts apprenticeship training and the challenges confronting female apprentices. The data retrieved were transcribed and qualitatively analysed using code-based content analysis. Findings indicated that the main factors motivating women to participate in construction craftspeople apprenticeship programmes are: the desire to acquire skills and intrinsic factors such as employment opportunities and better remuneration. Payment issues such as non-payment of allowance, and issues related to apprenticeship training, such as inadequate tools for training, were the prominent challenges faced by female apprentices in construction craftspeople apprenticeship pro grammes. The study identified factors that can be enhanced by stakeholders in construction craftspeople apprentice ship training to attract women to the construction industry.

    THE EFFECTS OF PSYCHO-SOCIAL FACTORS ON CONSTRUCTION EMPLOYEE PERFORMANCE
    (African Journal of Applied Research, 2026) Amusan, L.; Aigbavboa, C. O.; Jegede, O.; Ojelabi, R.; Aderounmu, P.
    Purpose: The aim of the study was to assess the Influence of psychosocial factors like competence, emotional intelligence, and education on construction firms' employees, with a focus on improving their performance on the construction site. Design/Methodology/Approach: This study adopted a quantitative descriptive survey research design. A random sampling method was used to select 20 medium-sized construction companies and 100 respondents. 100 questionnaires were administered. Analysis of Variance tool [ANOVA]. The relative agreement index technique was used to analyse the data. Findings: The findings provide a comprehensive, empirically grounded understanding of the multidimensional nature of employee performance in the construction industry, highlighting the interplay among psychosocial, organisational, environmental, and socioeconomic factors in determining on-site performance. Research Limitation: The study focused exclusively on medium-sized construction companies, thereby excluding small- and large-scale construction firms. This restriction limits the comprehensiveness of the findings, as the organisational structures, resource capacities, workforce compositions, and operational practices of small and large construction firms may differ considerably from those of medium-sized companies. Practical Implication: It provides guidelines for project managers and professionals on understanding the following as a key requirement to improve on-site output: Wages should be paid on time, allowing construction workers to participate in professional conferences, which also greatly helps improve competence. Social Implications: The deployment of financial and non-financial incentives can induce higher performance by meeting workers' social needs. Originality and Value: The findings of this study firmly establish that emotional intelligence is not a peripheral or incidental factor in construction employee performance but rather a foundational psychosocial competency that underpins goal achievement, teamwork, and professional resilience on construction sites.

    Government’s motives and investor’s commitment in public-private partnership procurement system adoption
    (Sciendo, 2025) Amusan, Lekan; Ojelabi, Rapheal Abiodun; Adewolu, Adeoye Olugbenga; Olanipekun, Oladeji Olubunmi
    The study examined the government’s motives - ment to infrastructure delivery. The study adopted a quan titative research method with a survey conducted using a structured questionnaire targeted at 384 respondents selected through random sampling. The data were ana lysed using mean, percentile and Pearson correlation sta tistical tools. The study identified 17 key motives respon sible for the government adopting PPP in socio-economic infrastructure delivery. These motives were factored into three main groups: public infrastructure maintenance, financial and economic benefits; improved discipline in the contractual relationship and predictable path in infra structure delivery and integration of innovative approach in enhancing infrastructure delivery. Therefore, the relationships between the three factored government’s motives and investor’s commitments, including finance, management, technical and operational services in PPP, were tested using the Pearson correlation statistical tool. The results showed that the motive for public infrastructure maintenance, financial and economic benefits of the government in PPP showed a significant relationship with the four services commitment of private partners. Also, the government’s motive for improved discipline in the contractual relationship and predictable path in infrastructure delivery showed significant relationships with technical, finance and management commit ments of investors. Lastly, the government’s motive for the integration of innovative approaches in enhancing infrastructure delivery showed a significant relationship with only technical commitment. The outcome indicates that factors measuring government motive and investor's services commitment are mutually dependent and critical in ensuring a sustained relationship among stakeholders in a PPP arrangement for infrastructure procurement.
