1. Introduction

Infrastructure has long been identified as a catalyst for economic growth. The demand for infrastructure development and the maintenance of existing infrastructure caused by economic growth and population increase has in many instances, overtaken the capacity of national governments to provide the necessary finance (Howes and Robinson, 2005). The estimates of investment needs for global infrastructure development ranges as high as US$3 trillion per year, of which approximately US$1 trillion per annum needs to be spent in developing countries (World Economic Forum, 2010). Howes and Robinson (2005) asserted that the estimate for developing the Asian region ranges from US$1 to US$2 trillion, US$600 billion for Latin America while Eastern Europe and Africa also need heavy capital infusions for infrastructure development. The inadequacy of infrastructure in Africa is widely recognised, particularly in Sub-Saharan Africa (SSA). The finance required to raise infrastructure to a reasonable level within the next decade is estimated at US$93 billion per year in Sub-Saharan Africa (World Bank, 2011).

5. Conclusion

It is evident that many public transport infrastructure projects are delivered through PPPs in the last two decades. The identification of the specific critical success factors (CSFs) for these PPP transport projects implementation is crucial. Considering the vast majority of previous related studies focused on the CSFs for general implementation of successful PPP projects. It is against this backdrop that this study assessed, identified and compared specific CSFs in the three PPP transport infrastructure project case studies comprised road, airport, and seaport in Nigeria. In achieving this, a set of 26 success factors were identified from the significant literature, which was used to design a case study protocol using FMEA method. Based on the foregoing, FMEA technique was used to assess the criticality of identified 26 success factors in the three PPP case studies. Thus, using similar CSFs provided a uniform basis and allowed like-for-like comparison between the three PPP case studies. In addition, personal observations and review of documentary reports were conducted in each case study to unfold the characteristics of events, and to describe the process of project conception and delivery, which led to drawn the lessons learnt in the three PPP project case studies.
