Item Public Private Partnership System Initiation Challenges for the Procurement of Public Infrastructure(Covenant Journal of Research in the Built Environment, 2024) Ojelabi, Rapheal; Oyenubi, Adebayo; Afolabi, BaruwaThis study investigates the severity of the challenges associated with the Public-Private Partnership system initiation phase in the procurement of public infrastructure. Also, strategies for managing the barriers associated with the procurement system were evaluated. The study adopted a quantitative research method, conducting a questionnaire survey targeted at selected PPP stakeholders, which includes Architects, Builders, Structural engineers, estate managers, and Quantity surveyors in Lagos and Abuja. The stakeholders were elicited from selected 19 PPP projects using a project-based approach. The data generated were analysed with SPSS 21 using descriptive and inferential tools. Findings from the study revealed the most severe factors associated with PPP procurement system failure to deliver public infrastructure at the inception phase, including a lack of PPP development fund to promote PPP, corruption among the political class, and investors' perception of the country as high-risk for investment. Likewise, strategies considered significant to managing the PPP initiation barriers were unveiled including establishing policies to facilitate PPP at the inception phase, improving transparency in information sharing and providing guarantee legal framework to protect investors. The findings will grant PPP stakeholders insights to the issues responsible for the termination of PPP project collaboration at initiation phase of the procurement system. Also, the unveiling of the PPP challenges and mitigating strategies at the inception phase could guide stakeholders in developing a framework to a successful PPP implementation in a bid to encouraging more participation at this level.Item 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, OpeyemiPublic-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.
