Purpose: This study examined the influence of risk management practices on the performance of public–private partnership (PPP) infrastructure projects in Nigeria. Specifically, it assessed how risk identification, risk allocation, and continuous risk monitoring impact project outcomes such as cost control, timely completion, and quality delivery.

Methodology/Design: The study adopted a quantitative research approach underpinned by a pragmatic philosophy. Data were collected from 460 employees and managers involved in PPP projects using structured questionnaires. Stratified random sampling ensured representative participation, and reliability and validity of the instrument were confirmed. Descriptive statistics and multiple regression analysis were employed to test the relationships between the variables.

Findings: The results revealed that all three risk management practices had a positive and significant effect on project performance. Risk identification, risk allocation, and continuous monitoring each contributed to improved coordination, reduced delays, minimized cost overruns, and enhanced overall project outcomes.

Implications: The findings highlight the importance of systematic risk management for both practitioners and policy makers. Emphasizing early risk detection, fair allocation, and continuous monitoring can improve the success rate of PPP infrastructure projects and strengthen governance practices.

Originality/Value: The study contributes to PPP literature in Nigeria by providing empirical evidence linking structured risk management practices to project performance, offering actionable insights for improving infrastructure delivery in emerging economies.
