| Key areas of urban building demolition reconstruction project with large investment, long period, the surrounding municipal pipeline complex, easy to damage the characteristics existing structures, and also more easily by projects of natural environment, economic risk, technological risk, and various social and political risk influence. Risk management in our country some key and large construction projects in a certain application, also achieved good results. The will to Shanghai free trade zone within the scope of the development of new emerging building reconstruction project based on by study on the characteristics of the project, combined with the surrounding environment and project the problems reflected in the process, the risk management theory into the actual work of the project progress, and better promote the safety of project cost carried out in an orderly manner.This paper studies the urban building demolition reconstruction projects in key areas of various risk factors in construction process, using the expert analysis method combining brainstorming method to identify the main risk factors affecting the project implementation process. And on this basis, build a high-rise building engineering construction safety comprehensive evaluation index system of risk management, set up the safety evaluation model of risk management of the construction site. The content of the risk management for engineering project has carried on the quantitative analysis, and obtained more accurate intuitive quantitative conclusion. The class more comprehensive analysis method is applied to the engineering project risk management made up for the lack of quantitative analysis of the shortcomings in this field. Using gray system theory method, effectively solve the’ old engineering risk analysis methods, a single, low accuracy’,’risk decision target a single’ and so on. |
