The method applied in this study comprises critical literature review, experts' interview and questionnaire survey within the Ethiopian construction industry. Data obtained was analyzed using an analytical hierarchy process research technique and an Expert Choice Comparison software platform. The findings revealed that affordability, quality, and innovation are the most important attributes to be considered for decision-making.
