Cost Dynamic Control Of Construction Stage Based On BIM Technology Research

As with advancing informatization in construction industry, more and more people and companies are gradually realize the importance of building information model(BIM), on the market of the design, budget, cost, etc. Some programs are gradually combined with BIM technology, and the new software also began to gain popularity, but it is not a quick results, to project cost control is not critical about change, so to establish the 5 d resources information system based on BIM will be very good to solve this problem.In this paper, using the BIM concept, based on the actual cost of database, plus makes the dynamic management of the construction information fully and share, make construction project information integration. At the same time, in view of the inside of the 5 d resources information system has its own control system, expounds the project progress payment from system one by one in order, engineering change management system, cost of earned value analysis system.Aiming at the complexity of the resources and the construction cost management and project construction cost over budget, through the establishment of 5 d resources information system, can be in the construction phase of manpower, material resources and material resources to realize the dynamic management and real-time monitoring of the cost, improve the level of project management for construction unit and the cost control ability provides a new breakthrough. And at the end of the article cites a real-time case using this system to control costs, the use of an intuitive feel for the system.
