Research on Influencing Factors and Control Measures of Construction Cost Overrun in China's Expressway Projects

In China, the expressways have been built a lot over past decade. The construction of expressway suffers from usual cost overrun. There are many factors different stakeholders influencing expressways, and it is difficult to control all them. Therefore, necessary identify key causing overrun take corresponding measures. this article, decision-making trial evaluation laboratory (DEMATEL), interpretative structural modeling method (ISM) system dynamics (SD) integrated as DEMATEL-ISM-SD driving simulate interactions these find A case in China has selected an example demonstrate how use proposed method. As result, six found. Then, measures put forward. This study can provide guidance for control.
