Research and application of cost control algorithm for engineering projects based on BIM technology

In recent years, the construction industry has experienced unprecedented development, and the rise in cost factors in various stages of engineering projects has made various project participants pay more attention to cost control work. It is urgent to strengthen cost control throughout the entire process of engineering projects to achieve profit goals. To reduce the cost of the projects, the study proposes a cost control strategy based on BIM. Firstly, the risk identification algorithm of engineering projects is proposed based on BIM, then the cost control model is constructed based on the risk identification results, and the genetic algorithm is added to the model to improve its performance, and finally the simulation experiment is designed to verify the effectiveness of the method, and the results show that the identification accuracy of the risk identification algorithm proposed by the study reaches 99.7%, and the C-C method based on BIM can significantly reduce the cost expenditure of engineering projects. The evaluation method proposed in this study evaluated the effectiveness, scientificity, feasibility, and generalizability of the C-C method by more than 90 points. The above results show that the application of BIM can effectively realize the cost control of engineering projects, which is of great significance to the smooth development of engineering construction.
