The role of public private partnership in highwayinfrastructure development and sustainability in Nigeria
type: CreativeWork
description: The Nigeria's highway infrastructure are currently being procured and maintained usingthe traditional Design, Bid Build (DBB) method. The procurement method and fundingmechanism appeared not to have produced the desired result of timely and cost effectiveproject outcome nor good quality and sustainable road network. This study set out toinvestigate the challenges being experienced in this traditional procurement method.The study also explored the features of Public Private Partnership (PPP) and itspotentials as an alternative procurement method for highway development, operationand maintenance, including developing and validating PPP framework for application inhighways in Nigeria.The study formulated two research questions - to investigate why the traditional methodhas not produced the desired result; and how the PPP method can play a role inachieving the desired highway project output. The research conducted literature reviewto examine the challenges of DBB method in Nigeria, and subsequently explored theconcepts of PPP generally and its particular application in highways. The researchphilosophy is majorly interpretive with minor positivists blend in a methodologicalpluralism for methodology enhancement. The research used case study research designwhere quantitative method was first used to investigate the current highway projectsperformance in cost and time perspective under the DBB method. The research alsoused qualitative method to analyse official documents and questionnaires to conduct anin-depth analysis of the highway Performance Indicators and their Critical SuccessFactors under DBB and PPP methods.The comparative analysis of the research findings showed that the DBB method usedfor highway development in Nigeria generally results in cost and time overruns, lowquality road network occasioned by the lack of adequate public financing, poor roadmaintenance management system, suboptimal risk sharing and lack of innovativeprocesses, and inefficient procurement p…
