Research On Construction Project Cost Management Based On BIM Technology

At present most of the construction enterprise cost management in China lack of a strict cost control and a periodic examination,the completion of final accounts exist the phenomenon of super budget,it should be a pressing matter of the moment about the construction cost management.However,the complexity of the construction process makes the project cost management become very complex,extensive cost information management can not meet the current needs,to a certain extent,it limited the application of traditional cost management methods.According to a project in Handan,with the help of BIM series software such as Revit and glodon’s software,creating a 3D information model,the preparation of schedule,cost budget documents,and preliminary integration in glodon BIM5 D platform.Then,according to the capital and resource curve extracted from BIM5 D platform,the 5D information model is optimized and adjusted,and provide a BIM5 D cost information database for project cost managemen.In the process of construction,the actual progress and cost information are input in real time,and the entity model is updated in real time according to the change,so as to ensure the constant updating of the cost information database,and realize dynamic management of resources and changes.At the same time,with the help of cost information database,combined with the improved earned value method,the cost deviation is found in time,and the deviation analysis is made quickly through the three calculation of resources,and the deviation response is made in time to realize the effective cost control.Through the application of BIM technology in the actual project,verify the BIM technology can provide data support for cost management,the application of BIM technology can help to realize the dynamic management of construction cost,provide the experience for future applications of BIM technology in cost management.
