Research on the application of BIM technology in commercial building construction management

The development of information technology plays an important role in building engineering design, construction, and cost management. This is intended to support the smooth progress of construction projects by optimizing the entire construction process, reducing engineering costs, and improving construction efficiency. In order to further improve the development of this field, this study combines the application of building technology with the project construction management process based on Building Information Modeling (BIM). In response to the demand for multi-objective optimization, this study established a multi-objective optimization model with two stages: time cost and time resource balance, and utilized this model to optimize resource allocation and reduce construction costs. In order to solve this multi-objective solving problem, genetic algorithm was used to solve the model, and the optimal construction management plan was obtained, which is suitable for large commercial buildings. During the construction process, as the construction period progresses, the construction cost gradually increases. Through the optimal construction management plan of this study, the optimal construction period of the project was determined to be 438 days. Under this construction period, the cost of this phase of the project is 2712.32 million yuan. Compared to the project planning cost, the total cost decreased by 17.05%. This result indicates that through the collaborative work of construction management mode and BIM technology, the entire construction process of the project has been effectively optimized. In addition, the construction management model of this study provides valuable benchmarks for the development of large-scale construction projects. It demonstrates how to use BIM technology and optimization models to improve the construction process, and provides a reference for the future development of more advanced construction management technologies.
