BIM技术在地震灾后重建房屋建筑工程造价控制方法中的研究
Application of BIM Technology in the Cost Controlof Post-earthquake Building Reconstruction

基于系统动力学控制重建房屋造价结果时，缺乏对地震后建筑成本数据的归集和处理过程，无法深入控制各个成本环节，控制效果差。深入研究地震灾区灾后重建房屋建筑工程造价控制方法，采用引入BIM技术的重建房屋建筑工程造价控制模型，通过该模型对建筑工程的造价成本进行预算，依据预算结果使用BIM技术归集成本数据后使用BIM数据平台存储和控制归集后的成本数据。通过造价控制体系实现地震灾后重建房屋建筑工程造价的有效控制，并采用财务ERP系统把控每个成本环节，实现工程造价优化控制。实验结果显示，该研究方法预算造价值与实际造价值差距小，约为1 000元，并在控制所有费用后节省了原始预算造价费用的11.91%，说明该方法造价控制效果好，能够有效节约震后灾区重建房屋工程造价成本。
Methods based on system dynamics for controlling the cost of house reconstruction have poor control effects because they lack processes for the collection and processing of post-earthquake building cost data and cannot control cost links in depth. A method for the cost control of post-disaster housing reconstruction in earthquake disaster areas is studied, and the cost control model for building reconstruction based on BIM technology is introduced. The model can be used to budget the cost of construction projects. Based on the budget results, BIM technology is used to collect cost data, and the BIM data platform is then used to store and control the collected cost data. The cost of post-earthquake building reconstruction can be controlled effectively by using the cost control system, and the financial ERP system can be applied to control each cost link to optimize costs. Experimental results obtained by using the proposed method reveal a small gap of approximately 1 000 RMB between the budget cost and the actual construction cost. After controlling all costs, 11.91% of the original budget cost is saved. The proposed method has a good cost control effect and can effectively reduce the costs of building reconstruction projects in earthquake-stricken areas
