In the past decade, both inside and outside of Japan, a lot of studies and researches have been done on the problems concerning the risk management process, the contract relation, and the development of risk analysis technique. But, there are very few studies discussing the project risk from the viewpoints of jobsite engineers. Especially, risk management, which has been usually processed in the empiricism, is not considered deeply on the construction sites in Japan. However, it is necessary to understand the quantitative mechanism of project risk to proceed risk management in the construction site properly, and set up the risk strategies by trade-off of risk and cost to reduce the project risk. This study started with using FTA to develop a quantitative analysis method, and using the data from the stakeholders of project to prove this method is useful. And, 650 risk occurrence causes in concrete description were emerged in a discussion with 40 project managers by brainstorming. Then, 32 risk occurrence causes were extracted by the method of two-dimension evaluation. Finally, the decision support system of risk management in a dialogue way was developed.
