Reasearch On Bidding Risk Management Of Engineering For Huangda Railway

The railway construction is basically dominated by the state and the source of funds is also basically state-owned,according to the bidding system of our country,the contractors of the railway construction must choose through bidding.Since the introduction of the bidding system in China in the 1980 s,although a complete system from top to bottom has been formed,which provides a solid guarantee for the development of bidding and procurement has also played an irreplaceable role in the field of Engineering construction,in practice,there are still many problems in bidding and bidding.Poor,it can be said that the risks are everywhere.Based on the relevant theories and risk management methods,this paper takes the Huangda Railway Station Construction Project(hereinafter referred to as "Huangda Railway")led by Shenhua Group as the research object,studies and analyzes the possible risks in the construction bidding process,in order to strengthen the standardized management of railway bidding.Work to improve the risk management level of railway engineering construction in China.The specific research contents are as follows:Firstly,the risk factors of Huang-Da Railway bidding are identified by three main methods: checklist identification method,risk structure decomposition method and expert experience identification method.The risk classification method based on the bidding objective is determined,and the secondary risk factors included in the bidding risk are mainly reflected in three aspects.On this basis,the risk factors are further divided into 15 categories and three level risk factors.Secondly,the importance of secondary and tertiary risk factors is evaluated by subjective scoring method and expert scoring method,and the overall importance of risk factors at all levels is evaluated by AHP from top to bottom.At the same time,through the analysis of the results of the risk assessment,the third-level risk factors are subdivided by the primary and secondary factor analysis method,and this risk factor is considered to be primary and secondary.Finally,on the basis of the analysis of the results of risk assessment,five principles of risk control for the Huang-Da Railway,namely,pre-control-oriented and pre-set worst,full participation and whole process identification,integration of overall control and special control,timely control and appropriate control,key implementation and consideration of the whole,are formulated and applied.Four risk control strategies have formulated the overall and special control measures for the risk factors of Huangda Railway,and explained the risk monitoring and control in the process of bidding implementation.
