Risk-based estimating combines both risk management traditional that includes project’s (Anderson et al. 2007). thus serves excellent technique generates reliable estimates. objective this research to: (1) Conduct literature risk-based (2) state-of-practice used by DOTs other construction organizations. (3) Based conducted, give recommendations how these practices be incorporated into MnDOT's business practice. reached through anticipated help MnDOT team get a better understanding estimating, could employed estimation
