A timely completion of construction project is a major criterion of project success. Failure to complete the project on time will ultimately result in delay. The need to control the causes of delays during the construction process comes out when the number of delay project has been increase from time to time. Hence, it is essential to identify the causes of this problem from the early stage of construction project.
The objectives of this study are to study the causes of delay in term of frequency occurrence and severity effect, and finally to identify the methods available to minimize construction project delays. A questionnaire survey was conducted to identify the significant causes of delay in order to avoid or minimize their impact on construction project. The perspective of construction parties has been analyzed and ranked based on Relative Important Index (RII).
About 49 respondents participated in the survey. This study identified the most important causes of delay from the list of 55 different causes and 22 recommendations to reduce the delay.
The study established that contractor's financial problem, poor site management and supervision and slow delivery of ordered materials are the major causes of delay in construction project. Finally, appropriate project management practices are thus identified to minimize the significant causes of delays in construction projects.
