    Effects of delayed payment of contractors on construction project delivery in Nigeria
    (The Construction, Building and Real Estate Research Conference of the Royal Institution of Chartered Surveyors, 2016-09-20) Akinsiku, O. E.; Ajayi, O.M.
    Delay in paying construction contractors has impacted negatively on the effectiveness of the contractor and as such affect project delivery schedule. Failure to pay contractors for work executed might lead to the contracting firm being insolvent. This research is a form of quantitative research and it a cross -sectional research survey which is a combination of descriptive and explanatory research design. The population of the study comprises of clients, consultant and contractors. A total of 65 questionnaires were distributed and 47 were returned and used for the analysis. It gives a response rate of 72%. Random sampling technique method was used, thus the respondents has equal chances of being selected. Statistical package for social sciences (SPSS 20th version) was used to analyse the data via descriptive and inferential statistic. The finding shows that the causes of delayed payment were unrealistic cash flow, error in claims, poor financial problems and disagreement on valuation of work. The impact of delayed payment is delay in project progress which affects the schedule of work and leads to cost overrun and extension of time. In conclusion clients should seek co- investors for support on financial commitment. It was recommended that the stakeholders should work as a team in the execution of project to avoid bottlenecks usually encountered in agreeing contractors’ payment.

    Utilization of public private partnership (PPP) for social infrastructure provision in Nigeria
    (University of Lagos Press, 2015-11) Akinsiku, O. E.; Ajayi, O.M.
    Public Private Partnership (PPP) has been widely used to deliver public infrastructure and services in most developed countries like UK, Australia and Canada. However in Nigeria, the implementations of PPP for social infrastructure have not been fully adopted despite the benefit of the procurement system in terms of the usage of private sector finances to provide public infrastructure. This study thus assesses the utilization of PPP for social infrastructure in Nigeria. Cross-sectional research design is used for this study and the population comprises of professionals involved in the execution of PPP projects, government agencies and parastatals, public and private institutions, and contracting organisation. Convenience sampling technique method is used for this study of which 68 questionnaires were distributed and 49 was returned and used for the analysis, given an average response rate of 72%. The study shows that the level of utilisation of PPP procurement system is very low as most respondents have not been involved in PPP procurement system in Nigeria, this is attributed to the fact that this procurement system is yet to be fully embraced and adopted as a means of providing critical infrastructural need although professionals are quite aware of the procurement system.
