The study aims at examining how effective Public-Private Partnership (PPP) procurement models in Nigeria are in enhancing the delivery of infrastructures. The study examined those factors that measure the effectiveness of public-private partnership procurement model in other countries from literature. Thus study employed a survey research design with a population and sample n Abuja. Data were majorly collected from primary source using questionnaire and data analysis used regression analysis and chi-square statistics. The result of the empirical findings showed that the three most effective factors with regard to publicprivate partnership 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 condition for renegotiation and positive environmental performance impact‟. These factors weakened the effectiveness of the publicprivate partnership procurement model and cemented the location of the model on the equilibrium framework in the industry‟s interest quadrant; while the regression analysis test indicated significant difference in the perception of public private sector respondents as well as the various groups‟ perception response. However, the chi-square test revealed that extant laws and guidelines were relevant factors for effectiveness of public-private partnership model. This study therefore recommended that stakeholders sensitise the citizens on the significance of Publicprivate partnership arrangement in developing and delivering infrastructure especially at this period with dwindling public resources and competing demand induced by limited financial resources.
