| The most important work in the process of building project management is the pre project cost control.The level of the pre project cost control will directly affect the cost of the project,which reflects the level and quality of the work in the process of construction project management.Therefore,the optimization and control management of the pre construction cost of the construction project can effectively improve the economic and social benefits of the construction project.This article first introduces the research background,the research content and the domestic and foreign research status of the construction project cost optimization control,then analyzes the content of the construction project cost optimization control in detail,introduces the construction project cost and related concepts,and analyzes the construction project cost control in different stages.Content and characteristics.The third chapter of this paper focuses on the analysis of the method of optimizing the cost control of the construction project,and uses the grey system theory model to make a qualitative and quantitative analysis on the cost control of the early decision stage of the building project.In this paper,the value engineering theory is used to analyze the cost control in the design stage of the building project,and an example is used to explain it.A detailed control method is proposed for cost optimization control in the bidding stage.At last taking the construction project of a university in Wuhan as an example,this paper further analyzes the theory and method of the early decision stage,the design stage and the bidding stage of the construction project,and demonstrates the practical effect of this paper on the theoretical research of the construction project cost optimization control.The full text is mainly based on the construction project.The three stages of early decision,design and bidding are the research objectives,the theory and method of cost optimization control are thoroughly analyzed and combined with the application of examples,which provide accurate theoretical guidance and good method for the construction engineering industry in the future cost optimization control,and the complex situation of investment environment at the present stage It has a very important guiding role in saving investment costs and reducing investment risks. |
