Cost Control Based On Earned Value Method Of Shanghai-Kunming High-Speed Rail From Changsha To Kunming

Effective cost control is the premise of profit, it is also directly related to the economic benefits of railway construction enterprise, thus it is important to carry out effective cost control, and minimize cost under the premise of construction safety and quality.High-speed rail construction projects has the characteristics of large scale, long period, complicated technology, large capital needs, etc, therefore, it is very difficult to control the cost of construction and needs advanced cost control scheme. Earned Value Theory uses the achievement to measure the progress of project, it can monitor the cost variance efficiently by comparing the planned cost、the actual cost and the earned value, thus it is an advanced cost control method and suitable for cost control of high-speed rail construction projects.This thesis introduced the dynamic cost control theory firstly, then analyzed the drawback of cost control method of China Road and Bridge company’s HU-KUN High-speed rail section II project. We have found that the method is lack of science and maneuverability, also has low integrated management level, which will increase the difficulty of cost control of this project. In order to achieve effective cost control of this project, the thesis design an Earned Value method and apply it to the project. Firstly, it puts forward the basic principles of dynamic cost control methods based on the analysis of investigation and data sorting. Then, we decompose the task from the aspects of roadbed engineering, bridge engineering, tunnel engineering, and ballastless track, and set a reasonable construction plan. After that, we establish planned cost value, earned value and actual cost based on the data of 2011, and design an earned value method which is suitable to HU-KUN High-speed Rail Section Ⅱ Project. By using this method, we can understand the relationship between the cost and the progress of this project clearly, which will enhance the strength of cost control.The earned value method can judge the execution effect of the cost and the progress and overcome the drawback of traditional cost control method, and can enhance the efficiency of cost control, thus, it will provide effective guidance to cost control for this project as well as other High-speed rail project in the future. However, it will be compelling if we demonstrate our viewpoint by providing more detail data, that is the direction of further research.
