| dc.description.abstract | This research attempts to assess the extent of effect of determinants of time overrun in road construction projects at various life cycle stage by analyzing the compound effect of impact and frequency of occurrence of 12 determinant factors composed of sixty-eight (68) time overrun factors identified from literature. Two determinant factors composed of 11 individual time-overrun factors during project initiation life cycle stage, two determinant groups consisting 11 factors during project planning life cycle stage and eight determinant groups comprising the majority 46 delay factors during project execution life cycle stage. Primary data was collected using questionnaire and SPSS 23 used for analysis. The study finds out the top three determinants of time overrun are Inefficient/insufficient Material and Machinery Management and Utilization and Poor Financial management System during execution lifecycle stage and Poor Data Collection during planning life cycle stage. The criticalness of the delay factors leading into time overrun increases as the project progresses; proportion of critical nature of delay factors leading into time overrun increases from 45.5% at project initiation stage to 67.5 % at project execution life cycle stage. The study also reveals, the responsible stakeholder for the delay causes varies for the different life cycle stages client being responsible during initiation and contractors during execution life cycle stage. Moreover, the researcher used ANOVA, Pearson’s Correlation Coefficient and regression analysis to test the relationship between variables and to suggest alternative hypothesis. The research also conducts secondary data analysis between 2016 and 2020 and find the number of projects getting into time overrun increase as the projects progress further | |
