Design-Build (DB) and Build-Operate-Transfer (BOT) contracts are the two types of public-private-partnerships that are widely used in the region that are aimed in this study. The objectives of this study were to analyze and compare DB and BOT projects in terms of project costs and durations. In order to analyze and compare Design-Build (DB) and BuildOperate-Transfer (BOT) projects, this study collected data by means of convenient random sampling, from construction projects built by five ministries of Republic of Turkey. Statistical tests were conducted to determine if the metrics related to cost and schedule were significantly different from each other in these two types of projects. The findings of this study will help the public agencies decide what delivery method is best for their projects in terms of controlling costs and schedule. Results show that DB projects outperform BOT projects in terms of cost and schedule. The results of this research will enable governments to become more familiar with comparisons between DB and BOT distribution methods, and the findings will help the ministries to choose swhich delivery method is suitable for use on a projectbased.
