Abstract
The construction industry is one of the main sectors that provide important ingredients for the
development of an economy. Construction is a tool through which a society achieves its goals of
urban and rural development.
However it is becoming more complex because of the sophistication of the construction process
itself and the large number of parties involved in the construction process, i.e., clients, contractors,
consultants, users, designers, subcontractors, regulators, and suppliers.
This eventually leads to delay in the completion of the project. Construction delay defined as
“time over run either beyond completion date specified in a contract or beyond the date that parties
agree upon for delivery of a project.” It is slipping over its planned schedule and is considered as
common problem in construction projects.
Delay in construction project completion is a global phenomenon that occurs in the construction
industry and considered as one of the most common problems causing a multitude of negative
effects on the project and its participating parties especially where the government projects are
concerned and in the construction industry of Ethiopia is no exception.
The objective of this study is to identify the major causes and factors of construction delays, their
effects on the successful completion of projects, and provide suggestions to minimize delays in
the construction of Educational Building projects under Addis Ababa University.
This study uses a comprehensive literature review to design and conduct a survey to investigate
delay causes and then filtered based on appropriateness to the Ethiopian Construction Industry as
well as the Educational Building Projects at Addis Ababa University. A specific survey was
conducted thru case study for selected projects to examine the most critical delay factors and their
effects. A general survey was distributed thru questionnaire to examine the correlation of the most
critical factors of delay and its relative effect on the project with respect to time, cost and quality.
Data was collected and analyzed using the ‘Relative Importance Index (RII)’ whereby the score
with the highest RII is one that mostly influences the delay.
