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

Our city urbanization is accelerated rapidly in recent years.The construction industry continues to expand,but the scale of the problem,such as industry cost management control,information exchange,low efficiency,large amounts of data not be shared by each other,are gradually exposed.This is restricting the development of the construction industry.Under this situation,the government pays more and more attention to the integration of information technology,and application of network-based collaborative work in engineering,so as to enhance the level of informatization in China construction industry,and catch up with international standards.Construction industry economy volume is huge,informatization construction is the foundation to change the development model.Cost target is one of the three major goals of project management,to improve cost management level depends on the information management platform.The use of information technology tools strengthens the comprehensive and interaction management of different stages in the project.Building information model(BIM)is a new type of information technology,which is promoted by the Ministry of construction.The advantage of BIM has been researched a lot in construction engineering,but in practical application BIM is most simulation in three aspects: pipeline design,space collision checks,construction schedule.The application in project cost management is not enough.BIM integrated architecture information,time information and price information,can achieve dynamic monitoring of schedule and cost.It is recognized as the effective means to improve the production efficiency and resources integration of construction industry,so it is very necessary to study the influence of BIM on project cost management and cost control in dynamic process.Through the reading of literature and combined with work experience,this study summarizes the innovation of the BIM technology and the development previous of earned value management.The advantages and disadvantages of several methods of project cost management are summarized too.This study explains the role of BIM in project cost management in detail,trying to use a combination of BIM technology and earned value management.BIM based on monitoring and Analysising of project cost can achieve real-time assessment on project cost prediction.The related theories are tested in the engineering example,and the feasibility and superiority of Earned Value Management Based on BIM in project cost management are demonstrated.This study found that BIM has the characteristics of parameters.When perfect coupling cost data and the project entity,it's effectively to the cost estimates.Information is interactive functioned by BIM,which can make up for the earned value management in the difficulty of date obtain.The defect of earned value management is that it can be easily influenced by human factors.BIM improve the earned value management process in order to optimize the practical significance.The research of this study involves the latest BIM technology in the field of architecture,and explores the application of BIM in cost management.The result is useful to improve project management level,strengthen the dynamic management of project cost,improve the utilization rate of construction resources.The result has positive theoretical significance and practical value,and also provides a reference for further research.
