FACTORS AFFECTING QUALITY OF CONSTRUCTION PROJECTS: IN THE CASE OF SELECTED BUILDING CONSTRUCTION INDUSTRIES IN ADDIS ABABA, ETHIOPIA

Abstract

In Ethiopia the number of building construction projects are increasing from time to time. Since quality of building construction projects is one of the traditional and global measure of building construction project performance, no matter what definition we follow for quality, it becomes very complex when we try to put it into the actual practice. Hence, poor quality project delivery is major problems that face construction projects inside the construction industries, and it’s of high concern to those who are involved in the industry. Thus, the study was conducted by selecting building construction projects from Addis Ababa, Ethiopia. The projects comprise different category of building construction projects such as office, commercial, apartment, multipurpose and hospital buildings. These study carried out and investigate factors affecting quality of building construction projects: in case of selected construction industries in Addis Ababa, Ethiopia. The study adopted literature review, a questionnaire survey, and descriptive survey research in order to achieve its specific objectives. And in order to achieve the overall study objectives, the research considered and examine independent variables (stakeholder engagements, project funding, construction materials, and project management ability) and moderating variable (project distinctive) against dependent variable (quality of construction projects). The research examined independent variables (stakeholder engagement, project funding, construction materials, and project management ability), and moderating variable (project distinctive) against the dependent variable (quality of construction projects). The data for the study was collected from a sample population of 273 respondents of selected construction industries of responsible departments related with the study, and it was arrived at with a 95% confidence level and an error of 0.05. The relationship proposed in the framework were tested using Pearson correlation, and the causal relations were analyzed using regression analysis. From the result of the analysis, it is concluded that there is the fact that both independent and moderating variables have a positive and significant influence on dependent variable which determined factor affecting of quality of building construction projects in Addis Ababa, Ethiopia, under the case study area has influenced by both independent and moderating variables significantly.
