Application of BIM Technology in Construction Cost Management of Building Engineering

Construction cost management is one of the three goals in project management. The level of its management is directly related to the profitability of the company. In recent years, construction companies have put forward more accurate and refined requirements for cost management. The more traditional cost management methods are it is difficult to deal with complex and changeable situations. Therefore, this article studies the application of BIM technology in construction cost management of construction projects is of great significance to the construction of Chinese enterprises. This article associates the cost plan with the schedule plan. The core is the component or the set of components. After completing the information association, the cost model is established. Finally, the earned value method is used to complete the control based on the good data support of the BIM-based 5D cost model. Time, space, and element dimensions fully control cost dynamics. With the help of BIM, this article can make up for the difficulty of data acquisition and easy to be affected by human factors in the earned value management method, and improve the earned value management process. This paper studies the latest BIM technology in the construction field, and explores the application method of BIM in cost management. Improve the information level of engineering project management, enhance the dynamic management of project costs, and improve the resource utilization rate of the construction industry. This paper uses BIM calculation software to convert the traditional CAD drawings into three-dimensional models, import them into BIM5D software, and manage them in detail during the construction phase. Its innovation is to use the three-dimensional building model to integrate various data information such as cost, schedule, information, and realize the sharing of data and various information. Research has shown that cost management has been simulated by BIM technology to achieve timely and accurate information support. In this process, the integrated control effect of schedule and cost can be fully utilized.
