ABSTRACT
The study examined effectiveness of Public Private Partnership (PPP) procurement model in Nigeria, following the identification of the factors that measure the effectiveness of PPP procurement model in other countries from literature. A questionnaire survey approach was used to investigate the perception of Nigerian Construction Professionals (having some PPP experience) on their relative effectiveness. Means score values from the 114 survey respondents were used to rank the relative effectiveness and also determine the direction of movement on the PPP equilibrium framework. The independent T-test and Analysis of Variance (ANOVA) were used to test the differences in the Public Private respondent's perceptions as well as the various interest groups perceptions regarding the effectiveness of PPP procurement model in Nigeria. The results showed that the three most effective factors with regard to PPP procurement model were "established demand", "risk apportionment to proper party", and "user fees long-term management". While the least effective factors revealed by the study were "transparent and objective selection criteria", third party consultant involvement", acquisition and procurement addressed by legislation", Clear and objective conditions for renegotiation and positive environmental performance impact. These factors weakened the effectiveness of the PPP procurement model and cemented the location of the model on the equilibrium framework in the industry's interest quadrant. While the independent T-test and ANOVA test indicated significant difference in the perception of Public and Private Sector respondents as well as the various groups' perception response. Based on the findings from the study, it is recommended that stakeholders need to sensitize the populace on the relevance of venturing into PPP arrangement in infrastructure development especially at this time when government is financially handicapped as a result of competing demand coupled by scarce resources.
