Research On Project Construction Cost Control Based On BIM Technology

This article introduces the cost management theory based on BIM technology through the literature research method,investigation method and case analysis method,and analyzes the application value and its necessity and effectiveness based on BIM technology in the traditional earned value analysis method and project cost control.Introduce the Silk Road trade industry project,establish a BIM5 D model,and propose BIM information flow topics,digital-analog separation and digital-analog correlation,promote the application of the entire process of information,using the collected project data as support,theoretical analysis as a guide,and model calculation as Basis,data processing as a means to analyze and evaluate the problems of low efficiency of bidding in the construction cost system of the project,unreasonable arrangement of project resource plans,and excessively extensive control of project material costs.The thesis focuses on the specific application of BIM technology based on the Silk Road Trade Industry Project in the project preparation stage,construction stage and completion settlement stage,and analyzes the advantages of BIM technology in the construction cost control process,clarifies its construction effect,and studies The main contents are:(1)Theoretical research based on BIM technology in project cost control: Through the research and analysis of the current status,development process and barriers to popularization of the application of BIM technology,it shows its value and necessity in cost control,and leads to China 's BIM technology.Floor solution.Prove that this technology can play a corresponding role in project cost management.(2)Based on the application research of BIM technology in the cost control of the construction stage: put forward the combination of each BIM5 D model and cost control to provide a visual management platform for the purchase of materials and progress control in the construction stage.Introducing and using this model to control costs during the construction phase is very feasible and necessary for the continuous development and innovation of the construction industry in recent years.(3)Empirical evaluation research based on BIM technology in the cost control of the construction stage: through the establishment of the Silk Road Trade Industry Project Model,the cost of each construction stage is analyzed and evaluated.Carry out real-time dynamic monitoring research,combine the determined schedule with the visual model simulation process,so that all subcontractors can also observe the corresponding work content,determine the corresponding working time,and scientifically adjust the staff,Materials,facilities entering the site,to prevent progress delays.Through the comparative study of the contract value,planned cost and actual cost of the traditional earned value method and the BIM5 D model,the cost deviation range of different links is obtained,and then according to the deviation warning set in advance,the judgment and analysis of the type of deviation aregiven to face different The deviations of the types are improved in time.The method established by the model not only can effectively control the cost,but also can track the completion progress of the project in real time.
