Research On Behavioral Risk Assessment Of Expressway Project Participants Under The Design-Build

Because of the characteristics of design-build general contract system, expressway construction projects subject also participate in the organizational structure and management authority in aspects such as than in present a traditional project contract system of the trend more centralization, which results in the expressway construction projects in the engineering construction participating subject in the process of subjectivity risk, which is the main body behavior risk and also more show prominent. So, in the design-build general contract system, specific analysis expressway construction projects involved in the behavior of risk of risk factors, a deep understanding of the project subject behavior of the generation of risk mechanism, deepen our understanding of the behavior of an integrated management and risk the main body behavior risk prevention, to the comprehensive promotion design-build general contract system in the expressway construction in our country in the fields of application, and has an important meaning.This paper summarizes the design-build general contract system in expressway construction of advantage, determined the in the design-build general contract system expressway project subject behavior of the concept of risk, describes the expressway engineering project subject behavior risks related characteristics; Separately from the main body behavior of its own characteristics and factors of the main body of the behavior of the main body of the behavior and organizational factors information integrity the three direction analyzes the main body of the expressway engineering project risk behavior the formation mechanism, and from the direction of the main body of the behavior of five of the main body of the behavior behavior risk factors are analyzed, and established a set of general contract in the design-build general contract system expressway project subject behavior risk assessment index system; Combined with engineering project subject behavior risks related characteristics, main body behavior in the engineering project for the assessment of the risks of set up with the extension analysis theory on the basis of the systeml, and the actual cases of application evaluation systeml based on the integrated risk management theory, to strengthen the expressway engineering project the behavior of risk management to put forward the corresponding proposal countermeasures.This paper preliminary discussions design-build general contract system expressway project risk behavior subject the formation mechanism, the main body behavior of the risk analysis of project risk factors and the construction project of the main body behavior risk index system, to strengthen the project subject behavior risk integrated management put forward the corresponding countermeasures, and will be of general contract extension design-build general contract system in China of the application of the expressway construction play a positive role.
