Application Research Of Earned Value Management Based On BIM In Construction Project Cost Control

As one of the three goals of project management,the success of cost management directly affects the competitiveness of construction enterprises.At present,theoretical research on construction cost control is quite abundant,but it is rarely applied in practical.It is urgent to apply theoretical research to practical construction projects,especially c combined with advanced information tools.Therefore,this paper studies how to use BIM technology and earned value management method to control the cost of construction project:In this study,the cost management of construction project and BIM Technology were studied,and the current situation and problems of project cost control were analyzed and summarized from the perspective of the construction company.The analysis shows that there are some problems in the cost control,such as unreasonable cost estimation,emphasis on technology but less on management,inadequate dynamic cost management and unclear cost objectives.BIM model covers all the information in the whole project life cycle,with the advantages of visualization,simulation and coordination,and can play a corresponding value in the cost management of each stage of the project.In the bidding stage,the quantities can be calculated quickly and accurately;before the construction stage,the scheme optimization and construction simulation can be carried out to effectively control the design change;in the construction stage,the resource elements can be reasonably allocated;in the completion settlement stage,the settlement accuracy can be improved.In view of the lack of application of cost management method in the actual project cost management,this paper studies an advanced project cost management method--earned value management method,which shows that earned value management is a perfect and effective management method for the joint control of progress and cost,but in the actual application,there is a large amount of data collection work and schedule estimation accuracy and cost changes are difficult to measure.The application of BIM Technology can solve these problems well.The BIM model has all the data of schedule and cost.Using the progress simulation function of BIM,the schedule can be accurately calculated on the basis of considering the impact of changes and other factors.In this study,how to effectively apply earned value management method in BIMTechnology to control project cost was studied.According to earned value management process and BIM model construction process and cost accounting principle,earned value management method based on BIM Technology was proposed and earned value management process was established.The WBS of construction project suitable for earned value management was carried out under the mode of bill pricing,and the 5DBIM model was established with the aid of BIM Technical progress simulation,engineering quantity calculation,cost accounting and other functions can quickly and accurately obtain the relevant cost data required for earned value management,then calculate and analyze the earned value management indicators,take Cost Performance Indicators(CPI)as the core to carry out cost early warning and take measures according to the warning level.This paper introduces the construction of BIM model and the cost dynamic control process of earned value management method,and through the monitoring and analysis of earned value management index,it can accurately understand the cost implementation and future trend of the project.The research shows that the application of earned value management method in BIM Technology not only improves the working efficiency of earned value management method,strengthens the management personnel's control of project cost,but also improves the information level of project.Figure 24 table 14...
