| Guangzhou subway project shield construction market is currently in the peak period, participating in the construction business more competitive, shield construction costs have been relatively stable and transparent, construction corporate profit margins have been greatly compressed. But at the same subway shield works are large and complex projects, often very harsh conditions faced, construction accidents occur frequently in difficult construction, high construction costs and a wide range of effects, faced with a lot of uncertainty in the construction process. Construction companies in order to ensure the ability to continue operations in the strict cost management also must be comprehensive, detailed and prudent risk management costs under each project. Reasonable costs to prevent the construction phase of the project is to protect the economic risk of construction project cost plan to achieve goals and enhance their market competitiveness of its construction important tool.On the basis of the cost of risk introduce domestic and foreign research progress on the construction of the Guangzhou subway project phase costs Shield How to manage risk were studied. Firstly, the project cost management and project risk management theory. Second, the combination of the Guangzhou Metro Shield construction phase characteristics, features elaborated shield construction phase cost of risk, scope and cost of risk management research, risk identification and evaluation of the cost of research and selection methods to identify the Guangzhou 23 Cost of risk factors Metro Shield construction phase, elaborated AHP 23 how to analyze the cost of risk, based on the three principles of the cost of risk prevention measures studied how to develop appropriate guidance, but also on the radar map on how to apply Cost Risk Warning studied. Finally, a Shield Project, proves the cost of risk identification, evaluation findings and management methods, and the results of this study are summarized and discussed. |
