Research The Cost Of Construction Project Management System Based On BIM

In recent years, with the application of modern science and technology in human society continues to deepen, information technology in many industries as agriculture, manufacturing, financial services, etc. have been widely used to make these industries can be significantly improved productivity. In the construction industry, due to the various stages of the construction process, a lack of effective collaboration, produce large amounts of rework, rework, adds additional construction costs, but in the traditional mode of two-dimensional drawings, among participants the exchange of information has been greatly hampered, and the resulting higher engineering costs and greater risk. Project cost management as an important part of project management, its success is the key of the success of the project.BIM as a modern IT platform by creating and using digital models to achieve the construction works of design, construction and operation management, according to its visualization, digital, collaborative, can be simulated, and other technical characteristics can be optimized for the parties involved in the construction of an information exchange and sharing provide a communication platform. In theory, the application of BIM technology in the construction of the entire process of project cost management, can effectively improve the entire process of construction project cost management in all stages of the work efficiency.BIM-based cost management to make the whole process of architects, engineers, cost engineers, construction side, the owners can be achieved in various stages of work, schedule more easily foresee the construction costs associated with the construction, to solve the phase split and fragmented parties problem, good to avoid the design and cost control aspects of touch, out of line design and construction, frequent changes and other issues.In this paper, the necessity of the current field of the whole process of construction cost management from departure, explained the whole process to achieve real cost management of some limitations: it is difficult meticulous management, data sharing is difficult, it is difficult to realize the entire process cost, data accumulation difficulties in project-level, enterprise-class management ability and other characteristics.Which leads to the emergence of BIM can solve these problems through the elaboration of functional advantages of BIM, reflecting the value of BIM.Finally, the case of BIM technology elaborated in the project cost management in the whole process of how specific applications; BIM in construction costs through the whole process of management of the application, in order to build an overall framework of BIM-based project cost management system, and the need these specific applications can be implemented, but also support the related art and related software support database. Thereby extending BIM cost management and cost-based BIM-based information database.These two parts of the project cost and improved architecture BIM-based joint support from the BIM technology in the whole process of cost management.
