Cause And Effects Of Delay On Educational Building Projects In Addis Ababa University- Case Study

The construction industry is one of the main sectors that provide important ingredients for therndevelopment of an economy. Construction is a tool through which a society achieves its goals ofrnurban and rural development.rnHowever it is becoming more complex because of the sophistication of the construction processrnitself and the large number of parties involved in the construction process, i.e., clients, contractors,rnconsultants, users, designers, subcontractors, regulators, and suppliers.rnThis eventually leads to delay in the completion of the project. Construction delay defined asrn“time over run either beyond completion date specified in a contract or beyond the date that partiesrnagree upon for delivery of a project.” It is slipping over its planned schedule and is considered asrncommon problem in construction projects.rnDelay in construction project completion is a global phenomenon that occurs in the constructionrnindustry and considered as one of the most common problems causing a multitude of negativerneffects on the project and its participating parties especially where the government projects arernconcerned and in the construction industry of Ethiopia is no exception.rnThe objective of this study is to identify the major causes and factors of construction delays, theirrneffects on the successful completion of projects, and provide suggestions to minimize delays inrnthe construction of Educational Building projects under Addis Ababa University.rnThis study uses a comprehensive literature review to design and conduct a survey to investigaterndelay causes and then filtered based on appropriateness to the Ethiopian Construction Industry asrnwell as the Educational Building Projects at Addis Ababa University. A specific survey wasrnconducted thru case study for selected projects to examine the most critical delay factors and theirrneffects. A general survey was distributed thru questionnaire to examine the correlation of the mostrncritical factors of delay and its relative effect on the project with respect to time, cost and quality.rnData was collected and analyzed using the ‘Relative Importance Index (RII)’ whereby the scorernwith the highest RII is one that mostly influences the delay.rnKey words: Educational building construction projects, Construction Delays, Causes of Delay,rnEffects of delay, Addis Ababa University
