    Factors Affecting Construction Project Performance: The Case of Ethiopian Institute of Agricultural Research
    (Addis Ababa University, 2022-06) Eyob Sisay; Teklegiorgis Assefa (PhD)
    The construction industry is a significant contributor to economic growth and plays an indispensable role in the Ethiopian economy. However, despite its importance, the sector is beset by a multitude of factors. The same is true for the construction projects of the Ethiopian Agricultural Research Institute (EIAR). This study, therefore, aims at identifying factors affecting the performance of the construction project in the EIAR. To this end, a questionnaire survey was conducted involving 31 factors categorized into 7 themes. A total of 92 respondents, of which, 80 respondents (60 from the EIAR staff and 20 from contractors) returned complete questions. The data was analysed using the Relative Importance Index rank method (RII) to determine the perceptions of contractors and EIAR staff towards the pre-identified performance factors affecting construction projects. Besides descriptive analysis, correlation and regression models were used to identify relationships and the extent of these relationships on the performance of EIAR construction projects. The analysis revealed that material price escalation, the economic and political environment, shortage of materials, and inadequate site management and supervision were found to be the most important factors negatively impacting project performance. Hence, proactive abutment measures such as including clauses for potential revision of construction contract agreements would likely improve project performance. Furthermore, encouraging and supporting contractors to improve forecasting of economic trends, assessing the external environment, especially the political and business environment, in line with continuous site supervision, could improve the performance of construction projects Key words: Performance Analysis, Relative Importance index and regression
