Studies have shown that project risks are responsible for the failure of most Public Private Partnership (PPP) projects. The study examined the critical risk factors associated with PPP housing projects. Data for the research was obtained through a questionnaire. The data were analysed using descriptive statistics and mean ratings. Corruption and bribery among contracting parties (0.681), Exchange rate volatility (0.621) Availability of development funds (0.599) and Change in government (0.580) were the critical risk factors identified. The study also indicated that project cost is highly influenced by lack of development funds and changes in interest rates. The quality of PPP housing projects in Abuja was found to be influenced by partner selection risks. The study suggested a competitive, transparent, and efficient bid process to eliminate corruption, workable strategies for ensuring the availability of development funds at a cheaper rate and adopting mixed strategy in which government continues to provide social housing to the low-income class while providing the enabling environment for the private sector to thrive.
Public private partnership projects have been adjudged to contain more risks than traditionally procured projects due to more number of parties involved and their varying interests. These risks affect the achievement of projects objectives and therefore need to be identified and treated to guarantee project success. This paper developed a life cycle framework for managing risks in PPP housing projects in Nigeria. The respondents were selected using purposeful sampling technique. The data used for the study were obtained through semi-structured questionnaire and were analysed using mean rating. Risk transfer was found to be the widely used measure for responding to risks in PPP housing projects. The criteria mostly used for risk allocation were party with the best ability to manage specific risks should they occur and ability of the party to foresee risks. A four-stage life cycle framework was developed, evaluated and validated by experts in the built environment to ascertain its reliability. The framework is recommended for PPP housing projects in Nigeria.
