As the engineering project have the following characteristics, for instance, numerous participants,
complex technology, difficult construction and long construction period etc... Parties of the project
involved in the project implementation process are inevitable to face a large number of risks. These risks
will not only decline project economic benefits, even making the project failed. Engineering enterprises
of China are weak to resist risks; they lack of effective, standardized and scientific management
procedures. Engineering project risk management is the weakness in our country constructions field; it
has not form a system. Therefore, the project risk management is of great significance, which is not only
relates to the quality of the project directly, but also directly affects project cost. We should effectively
guard against various possible risks in the process of engineering project construction. To avoid
unnecessary consequences of loss, guarantee the smoothly implementation of engineering project. [1]
In order to efficiently control the schedule, cost, quality and safety of project, we must carry out
project risk management. It is a process that measure of project risk and select, develop risk treatment
options. Risk management in engineering project in China began in the late 1980s, the development time
is not so long that still have following problems:
