Factors Affecting construction projects Performance in Jimma University

Abstract

It is apparent that the construction industry is a very important part of any country’s growth and it highly contributes to the growth and development of the economy in developing countries. Construction projects suffer from several problems and difficult matters in performance such as cost, time and quality. Jimma University construction projects were similar to that. This thesis tries to identify the main factors affecting the performance of construction projects in the institutions. A questionnaire survey was conducted which are classified in to 7 clusters, 90 Questionnaires were disseminated, and 78 questionnaires were returned: 13 (86.7%) from owners and 65 (86.6%) from contractors. The results were analyzed using relative importance index and multiple linear regression analysis to determine owners and contractors’ awareness toward the performance influencing factors in construction projects and to see independent variables effect on dependent variable (construction project performance). The study found that independent variables showed significant relation with the dependent variable and the independent variables describe 41.3% of variance of the dependent variable performance of construction projects in Jimma University. The contractor related factors and labor and material related factors are the most influential that delay the project success in the jimma university construction project performance with average of Relative Importance Index (RII) equals 0.723 and 0.722 respectively. Project characteristics relate factors are the least influential factors in the jimma university construction project performance with average of Relative Importance Index (RII) equals 0.582. Contractors should have enhanced further for skilled workers who are accessible in all sides at both office and position that will solve associated problems on appropriate construction management, quality of work, cost control and time management. There should be government and projects owners who are selecting a competent contractor for a job that is serious for the successful delivery of a construction project and to solve the problems of the escalation of material prices and improper quality of materials in construction projects.
