Abstract
The Rwandan construction industry contributes up to 7.4% of the total GDP of 2010, yet its performance within the economy has been, and continues to be, very poor due to cost overruns resulting to abandonment of of projects. system procurement is still dominant in the Rwandan construction sector and this may likely continue to be the trend. Delay in project execution is a major problem in the Rwandan construction industry. This occurs both in small and large projects. Virtually, all the projects executed over the years in Rwanda were faced with problem of delay in delivery. The primary objective of the study is to analyze the influence of procurement systems on construction projects. Specific objectives are; to identify the extent to which various procurement systems commonly used by project managers in Kigali for construction projects, to examine when The traditional design-bid-build influence of procurement systems encountered employing various procurement systems for construction projects, to assess the merits and demerits of the various procurement systems on construction cost, develop a framework of procurement factors influencing delays. For the research design and methodology, the research will be carried out in Energy Development Corporation Limited as one of the institutions highly involved in the procurement and execution of construction works in Rwanda. The descriptive and explanatory approaches were done during the research and qualitative and quantitative methods were considered as well. About the sample size and target population, the researcher considers 21 as target population and census technique was used. Data analysis used spread sheets, SPSS and other statistic graphs and tables. The data The type of validity used by the researcher for this study was the content validity. For the reliability of the data collection instrument, Test- retest reliability was used. It is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The findings guided the researcher after analyzing data, to systems collection instruments were questionnaires. observe the influence of procurement on construction projects in Rwanda.
