| Construction project cost-control is known as an important aspect of project cost-control in 21st century. And the level of cost-control is the embodiment of the integrated management. During the cost-control process the relationship between the cost and the schedule is the most important aspect, lack of anyone will bring a certain degree of deviation. As a method of modern project management, earned value theory plays an important role during the management, and it makes enterprises to get the maximum long-term benefits.For the need of practical work, combining with Yantai Media International Building Project, the thesis analyzes the cost structure, and puts forward corresponding to solve methods about how to use modern cost-control theory to reduce the construction cost and shorten the construction period. Firstly, the thesis introduces the present situation of construction project cost-control, and puts forward the aim of research and the key ideas. And then introduces the content of cost-control theory, cost-control process, the principles of cost-control and the methods commonly used, especially the earned value theory and its development, basic step and data. As the theoretical basis of research, combining with the actual situation of Yantai Media International Building Project, the thesis introduces the basic situation and the characteristics of project, cost analysis, cost-control measures, and take the earned value theory advantage analysis, establishes the implementation plan for the project based on the earned value theory, prepares the cost budget, establishes monitoring points. When cost deviation appears, it will takes organizational measures, economic measures, technical measures and contractual measures to correct the deviation. And then the project cost estimation and earned value theory evaluation will be completed to achieve the ideal cost-control.Earned value theory, which successfully implemented proves that it is a scientific and effective cost-control method, which using money instead of quantity to measure the progress of the project. It finds the initial experience of project cost-control and project performance analysis, which will offer investors some basis for the next decision and is worth learning and using for reference. |
