Abstract

ABSTRACT
The purpose of this was to investigate the factors which influence Private Public Private (PPP) projects and specifically focused on the Nairobi Southern By-Pass (NSB) which is located in Nairobi Kenya. There is significant growth in the use of PPPs in the road sub-sector in Kenya. There is therefore a need to provide recommendations to ensure that PPPs are implemented successfully in order to avoid pitfalls. This will provide valuable information to county governments, public authorities, managers and contractors. The objectives of the study were: to establish the influence of procurement process on implementation of the Nairobi Southern Bypass (NSB) PPP road project in Nairobi County, Kenya; to assess the influence of route corridor availability on the implementation of NSB PPP road project in Nairobi County, Kenya; to examine the influence of politics on the implementation of NSB PPP road project in Nairobi County, Kenya and to determine the influence of budget on implementation of NSB PPP road project in Nairobi County, Kenya.
The study was a qualitative case study where primary data was collected through key informant interviews. Sampling was done using snowballing where 31 respondents were identified- these comprised of staff working at the specialized PPP unit and the department handling special projects within China Road and Bridge Corporation (CRBC) who was the contractor implementing the project and the Kenya National Highways Authority (KenNHA). To ensure the research instrument was reliable, the study conducted a pilot study which was composed of 6 respondents that were staff of the supervision consultant. The staff chosen for the pilot had previously been part of the intricacies in the NSB project right from procurement to construction. Analysis of the data was done using content and thematic analysis where the data was escribed in detail, interpreted and conclusions drawn. The findings of the study showed that procurement process influenced the commencement time, cost and alternatives in terms of design options for the NSB project. The study found out that while politics did not influence implementation of the project, budget considerations influenced implementation of the project as delays in disbursing funds either led to slowing down of works or additional costs in terms of accrued interest on delayed payments and contract prolongation costs. The major limitation of the study was that respondents especially from the Contractor were not willing to disclose full information citing business confidentiality as the main reason. In conclusion, the NSB PPP project was procured very fast and had a very fast turnaround time and could have been completed even faster had the route corridor been fully available and payments made promptly. The study recommends that implementing agencies should check thoroughly and consult with stakeholders on extent/scope of projects to avoid interference by politicians. The study further recommends that prior to commencing construction work, the route corridor should be fully available to the Contractor, free of encumbrances which could facilitate completion of the project within time and cost. The study also recommends that for faster turnaround time, implementation of such projects should only be done once all finances are in place. The study expects participants of PPP road projects in the future will find the findings of this study useful in order to maximize the rate of success when implementing similar PPP projects in addition to ensuring that resources that are invested in PPP programmes are efficiently and effectively used to have a greater overall project impact.
