Application of WBS Method in Risk Identification of Expressway Electromechanical Engineering Construction Period

The WBS method is used to implement simple identification of risk source in expressway electromechanical engineering construction,which includes the identification of risk source in such stages as associated design,equipment procurement and approach,equipment installation and debugging,and equipment testing.Through identifying the risk source in expressway electromechanical engineering construction,and analyzing the evaluation,response and control of risk further,the risk prevention scheme can be instituted,thus the loss can be reduced as much as possible during engineering construction,and the time limit for a project can be achieved.
