Özet: 'Abstract The construction industry is a huge industry that affects the economy of a country in a significant way. Cost overrun in construction is said to happen when the final cost of the project exceeds the estimate of the budget. Time delay or time overrun are terms that are used to describe the delay of construction work from the contractual or the planned duration. The objective of this research is to evaluate the extent of time and cost overrun in the Ethiopian construction industry. Moreover, to identify the factors that are causing time delay and cost overrun in Ethiopia. The research is divided in to two. The first part is a detail case study done on 9 governmental projects each worth more than 1 million USD and all commenced and completed in the last 15 years. Cost overrun observed ranges from 8% to 75.90% with an average of 30.6% and standard deviation of 23.1. The time delay observed in the case study ranges from 56.81% to 230.80% of the contractual time duration of the project with an average of 111.63% and a standard deviation of 58.1. The analysis of responses from 104 professional in client, consultant and contractor offices using relative importance weights (RIW%), have shown that the most influential factors for cost and time overrun are the factors related to staff. Lack of qualified staff, inflation, escalation of material prices, poor coordination between the construction project manager and high level management are the highly ranked factors. One of the challenges of this research was accessing data of projects to be used for the case study. Further works can be done by classifying the projects into governmental, private and public projects. KEY WORDS: Cost overrun, time delay, KJ method, Relative Importance Weight, Radar charts, Ethiopian construction industry'
