Research On Risk Assessment Of Highway Project Under BOT+EPC Mode

With the development of socialist modernization,China has continuously increased investment in infrastructure construction.As an important infrastructure,the highway project has high investment cost and long construction period.Under the complex construction operation management mode of BOT+EPC,it will help alleviate the financial pressure of government departments and improve the construction efficiency of the project.This article takes the risk assessment of highway projects under the BOT+EPC model as the research object.First of all,based on the relevant theories of the BOT model,specifically analyze the definition of the BOT+EPC model,the main participants and responsibilities of the project,and compare and analyze with the traditional model to obtain the advantages and operating difficulties of the BOT+EPC model;Secondly,using the WBS-RBS method to decompose the work tasks and risks of highway projects under the BOT+EPC mode from the perspective of the general contractor,construct a risk identification matrix,and obtains the risk indicators of the highway projects under the BOT+EPC mode through expert questionnaire surveys;Then introduce in detail several commonly used risk evaluation methods and makes a comparative analysis,determine the method using the combination of analytic hierarchy process and fuzzy comprehensive evaluation method,and explains the reasons for selection,and describes the evaluation process of the two methods in detail and build a risk evaluation model for highway projects under the BOT+EPC mode;Finally,carry out risk identification on the GS highway project under the BOT+EPC mode to obtain a risk evaluation index system and a project risk hierarchy,use the analytic hierarchy process to calculate the comprehensive weight of each risk factor,and use the fuzzy comprehensive evaluation method to determine the risk level of the project.After the qualitative analysis of the risk evaluation results,countermeasures are proposed for the main risk factors,providing a reference basis for the risk management research of highway projects under the BOT+EPC model.
