| Abstract: | Despite significant public investment in construction projects, they rarely meet planned schedules,
costs, and quality standards. This study assesses the performance of public construction projects in
Addis Ababa across three dimensions: schedule, cost, and quality. Data was collected via
questionnaires from 122 respondents, including project managers, resident engineers, and
counterpart engineers. The Relative Importance Index (RII) identified critical factors affecting
performance gaps, and ANOVA, correlation, and multiple regressions were used for analysis.
Findings reveal average variances of -117.84% in schedule, -32.37% in cost, and -17.95% in quality,
with statistically significant differences among project types. Schedule variance positively impacts cost
variance, and quality variance positively affects schedule variance. Key factors contributing to
performance gaps include ineffective planning, poor site management, financial difficulties, delays in
payment and site delivery, low-price bidding reliance, design approval delays, and external issues like
price escalation and utility unavailability. |
