Nigeria’s infrastructure deficit has become acute because of the country’s burgeoning population. The Public-Private Partnership (PPP) model, under labels such as Private-Finance Initiative (PFI) and Build Operate-Transfer (BOT), has been touted as the solution to the funding and other challenges confronting the country with regard to infrastructure development. This research sought to examine stakeholder experiences and perceptions on the benefits, abuse and challenges of deploying PPP for infrastructure procurement. The stakeholders investigated were in Lagos and Ogun States of Nigeria, although some of the experiences transcended the two states. Copies of the questionnaire were purposively administered to 115 professionals drawn from the built environment as well as from the legal and financial sectors of the Nigerian economy; the professionals were from the private and public sectors. Eighty-six (86) copies of the questionnaire were returned, with the data subjected to descriptive and inferential statistical analyses. Ranking highest among the list of thirteen identified challenges investigated was ‘political interference outside the agreed rules of running the PPP framework’, while ‘inability to initiate or package PPP projects’ ranked least. The most significant form of abuse or disadvantage was ‘embezzling of public funds and reinvesting in PPP as private sector investor’, while the least significant form of abuse was determination of the concession period. The inferential statistical analyses found no significant difference between both sectors in the assessment factors except in the matter of ‘more careful approach in investing funds in infrastructure’. It is therefore recommended that there should be a continuous audit of stakeholder perceptions on various PPP issues that can form the baseline for impactful improvement and intervention in PPP projects.
