    (Addis Ababa University, 2017-02) Yohannes, Aschalew; Kahssay, Oirmay
    This research analyzes the extent of cost and time performance of public building construction projects in Addis Ababa and tries to identify the critical factors that influence cost and time performance of public building projects in Addis Ababa. Secondary data and questionnaire survey were used to collect relevant information. Secondary data analysis results shows that there is statistically significant variation in the cost and time performance of public building construction projects in Addis Ababa. The outcome of secondary data indicates that 74.3% of public building construction projects in Addis Ababa experienced cost under run and the remaining 25.7% projects were experienced cost overrun. Out of this 74.3% projects, 40% of the projects varies with more than negative 20%. Project time overrun of public projects is a critical problem of the construction industry. The research finding points out 100% of the projects delayed and not completed within the time stated. The minimum and the maximum time overrun is found to be 10% and above 250% respectively. Also to identify critical time and cost performance factors RII (relative importance index) value of each factors was calculated and for each parameters the top five critical factors were identified. Finally based on the findings and results some recommendations were given

    he objective of this study was to assess the effectiveness of technical evaluation process in selecting building contractor in Addis Ababa. The conceptual framework was designed by considering technical evaluation process as dependent variable and technical evaluation criteria, procurement ethical standard, basic procurement principle as independent variable. The data were obtained by closed-ended questionnaires consisted of 37 questions with five-point Likert scale. Both Descriptive and inferential statistics were used to analyze the data and interpretation of the results. Pearson Correlation analysis shows that there was statistically significant positive relationship between all independent variable; technical evaluation criteria, ethical standard, and basic procurement principle and dependent variable; technical evaluation process. Moreover, the regression result revealed that technical evaluation criteria, ethical standard, and basic procurement principle were found to have their own positive and significant effect on technical evaluation process. Basic procurement principle was found to be the most predictor of technical evaluation process. Technical evaluation criteria and ethical standard had also significant contribution in predicting technical evaluation process in their respective order. The mean score result of basic procurement principles, procurement ethical standards and technical evaluation criteria are 3.86, 3.80, and 3.73 respectively and the mean score result of assessment of general opinion of respondents about technical evaluation process is 3.77. In general, the technical evaluation process is not carried out at the required effectiveness level and the researcher concluded that the technical evaluation criteria, ethical standard, and basic procurement principle could have positive significant effect on technical evaluation process
