Construction Cost Control Strategy of Finished House Based on BIM-5D

Building Information Modeling (BIM) technology can not only achieve project refinement management of the construction process based on a 3D model but also form a BIM-5D model based on the fusion of progress data and cost data to achieve the dynamic control of the whole process of project cost. This paper discusses the application of BIM-5D in the cost control of finished house construction, aiming to provide technical reference for China’s finished house project units, so that they can master how to realize the construction of cost control system based on BIM, the monitoring of the key coefficients of the cost, corrective action, to ensure that the project cost deviation is within the controllable range, and to make an effective guarantee for the economic benefits of the project construction.
