BIM-Based Cost Management In Building Construction

In recent years, with the rapid development, the construction industry has become the national economy of pillar industry in our country. The low efficiency and the serious waste phenomenon are particularly prominent inthe construction industry, we must pay attention to the cost management. However, the construction stage as the main stage of resource consumption and cost, cost management in which will have a great effect on the whole profit of the project, we should take a good control in cost at the construction stage.The traditional construction project cost management exist over time limit for a long time, over budget, low efficiency management and etc., lack of refinement of the modern management. As the big data Information wave hit, the concept of BIM (Building Information Modeling) is put forward, the deepening and development to the construction market has brought a new revolution, through the application of visualization, Information characteristics of BIM technology, and construct a Information accurately convey Information Modeling three-dimensional entity model, for improving calculation accuracy, reduce the cost,speed up the construction schedule, reasonable control changes, realize data sharing between departments and coordination is of positive significance.In this paper.the application of BIM technology as the background, on the basis of literature review, Combined with the traditional cost management theory, through the research of the current construction cost management and the application of BIM technology,find existing problems and realistic demand, which leads to the BIM technology in construction cost management inaspecific research and application of the final combined with the actual construction cases,BIM technology was introduced in detail with the method of contrast analysis the use of each stage in the aspect of cost control play a significant effect.This article mainly from the cost management of the construction cost management stage, the construction cost management stage, the completion of the settlement cost management stage three aspects, show the BIM technology brings to the construction cost management of huge economic benefits and social benefits, promotethe application of BIM technology in the constructionin our country.
