  7. Abstract:
  8. Project cost overrun is one of the most frequently occurring issues in the construction industry. Past research studies have investigated the project cost overrun problem from various perspectives. However, to date, only a few studies have focused on the identification of the root causes of projects cost overruns. A close review of these studies reveals that the studies often provide limited insight into the root causes of project cost overrun. These studies fail to consider the impact of project delivery system as a defining project characteristic that may influence construction cost overruns. In addition, past studies have relied on surveys that are not necessarily precise and highly reliable sources of knowledge. This paper investigates the root causes of construction cost overruns in Design Bid Build (DBB) construction projects. It uses Delphi method to obtain highly reliable information from experts. As part of this study, a comprehensive review of literature was conducted to identify the factors that lead to cost overrun in DBB projects. 495 factors were initially identified. These factors were later reduced to 113, and then 38 unique factors. Factors classified based on their common root causes. Using the Delphi methods, each factor, its root cause, and their relationship were verified in the context of DBB construction projects. This study contributes to the body of knowledge by enhancing the understanding about root causes of cost overrun factors. From the practical view, it enables practitioners to plan for the elimination of root causes of cost overruns not the symptoms that are associated with them
