| Abstract: | Delays in road construction projects have detrimental effects on project performance, including time,
cost, and quality. This research investigates the causes and impacts of delays within the Addis Ababa City
Road Authority. A cross-sectional mixed method design was employed, combining quantitative and
qualitative data collection methods. The study involved 44 participants representing clients, consultants,
and contractors. Questionnaires and interviews were conducted to gather primary data, while secondary
data from project progress reports and literature reviews were also utilized. The collected data were
analysed using descriptive statistics and the Relative Importance Index (RII) to rank the causes and
effects of delays. The study identified key causes of delay, such as slow approval of drawings, payment
delays, inadequate planning, right-of-way issues, traffic congestion, material shortages, and poor site
management. The effects of delay were assessed, including time and cost overruns. Recommendations
were provided to mitigate delays, including expedited decision-making, timely payments, improved
communication, enhanced coordination, and training. By implementing these recommendations, road
construction projects can improve efficiency, reduce delays, and deliver high-quality infrastructure. |
