Grid Construction Project Risk Assessment Of Wenzhou

By the modern theory of project risk management and based on the life cycle of power grid construction project, the risks of grid construction project are identified and evaluated from many perspectives in this work and approach to improve the risk control system are put forward.By way of the risk theory of the power grid construction project, appropriate investigations and assessment methods are chose according to the actual situation of the risk management of Wenzhou Electric Power, and risk factor matrix questionnaire is designed from the angles of the life cycle theory and the view of the risk management. In the quantitative investigation, due to the small number of experts and the different areas of expertise and professional experience, a comprehensive expert weight is determinate by integrating expert judgment levels and job qualifications of expert. And expert weight of job qualification is based on the working scope, working years of expert, and the quantity of project that expert has done.All kinds of risk factors in each management phase of power grid construction project are identified and assessed by rating score. According to the expert weight, each risk factor is valued and proper graded. From two dimensions from the project life cycle and the risk types respectively, a detailed analysis is presented. Respectively from the horizontal (type of risk) and vertical (life-cycle stage), the values of the sum of risk factors better show the important stages of risk (transforming civil engineering construction, line construction and installation project and policies to deal with land acquisition) and important aspects of risk(cost, program schedule and technical standard) of power grid construction.On the basis of risk identification and evaluation, moreover, risk control problems from the existing project and their reasons are discussed and analyzed. According to the quantitative research of the possibility of the risks and the harm degree of the project risks, source structure of the risk is analyzed. Through the selected 26 key risk management files of construction project, executing condition and existing problems are investigated and analyzed; and analysis on project risk management system is made.Finally, by the modern theory and method of project risk management, and by the standardized management and project management thought proprietorship, the systematic measures to prevent project risks are put forward. According to the key risks from power grid construction projects, the risk control strategies to the grid construction projects are designed. Based on the important stages of the grid construction project, project risk checklists of risk control are given and a complete set of risk management countermeasures are made.
