There were numerous complaints regarding the quality of building projects ran by the Department of Building and Engineering Services (DBES) in Botswana. The aim of this study is to evaluate participants involving DBES projects by using 16 factors in the project design phase which may influence the quality of building projects. Empirical results show that DBES lacks commitment to continuous quality improvement and poor use of lessons learned to improve quality. The key focus area is adherence to project management principles and poor level in this area may contribute towards DBES's poor project quality. Moreover, this study identified 3 types of groups based from the respondents' attributes and explored the differences in group means.
