Critical factors affecting schedule performance
A case of Ethiopian public construction projects – engineers’ perspective
Time overrun is one of the most significant issues being faced by Ethiopian construction industry today. For effective time performance, the successful execution of construction projects and keeping them within prescribed schedule is very important. The purpose of this paper is to determine the factors responsible for impacting performance of Ethiopian public construction projects.
Based on the literature and personal interviews of key construction professionals in Ethiopia, a list of 35 project performance attributes having strong effect on performance of the projects were identified and a questionnaire using these attributes were prepared and administered in Ethiopia. Statistical analysis of responses on the attributes segregated them into distinct sets of success attributes and failure attributes. The attributes were also subjected to factor analysis separately for better understanding and it resulted into six success factors and six failure factors. The relative importance of these factors was established with multiple regression analysis.
It is concluded that the success factor “owners’ competence” can significantly contribute to schedule performance of Ethiopian public construction projects. On the other hand, “conflict among project participants,” “poor human resource management,” and “project manager’s ignorance and lack of knowledge” are detrimental to schedule performance of Ethiopian public construction project.
As with any other opinion-based study, the present study also has some limitations. The majority of respondents have evaluated the projects in their execution stage only and very few have evaluated the performance of projects in planning and operation stages and also the study has been carried out in the Ethiopian context. Hence the study has a limitation in these regard.
The results presented in this study provide sufficient evidence and useful understanding to researchers and industry practitioners to focus on a few factors than giving attention to all the factors and take proactive measures for the timely delivery of public construction projects.
