How to use BIM technology for cost control in the production stage of precast buildings
At this stage, when the designer expresses the design intent of the component to the component manufacturer or adjusts the detailed structure of the component, the component production often fails to meet the design requirements due to the understanding deviation.
In the production stage, the use of BIM technology can also realize the linkage of precast components.
When the component is completed and installed on site, the error can be found, which leads to the secondary processing of the component, Increased component production costs.
The cost in the production stage accounts for a large proportion in the whole construction process of precast buildings, and cost optimization in the precast production stage is of great significance to the entire project.
(1) Under the traditional production mode, the information transmission is completed through two-dimensional drawings.
Through the three-dimensional model of precast components, the intention of designers is more clearly displayed, and the production efficiency of precast components is effectively improved.
This section puts forward feasible suggestions for the production stage of precast buildings by studying the production stage of precast buildings and exploring the application of BIM technology in the production stage of precast buildings.
(2) In the component production and design stage, BIM technology is used to parameterize the definition of each precast component, so that each component can be linked, and other related components will also change when the component is adjusted, so as to achieve the effect that each component can move the whole body.
In the production stage of precast buildings, by combining BIM technology with RFID (Radio Frequency Identification The accuracy of the installation process, the real-time feedback of the storage, quality and other information of the precast components has realized the linkage of the whole assembly process, thus ensuring the goal of zero inventory and zero defect of the precast components in the production stage.
In addition, when design changes occur, component manufacturers can directly conduct real-time viewing through 3D models, avoiding production errors caused by delayed information transmission, thus optimizing the cost in the production phase of precast buildings.
The BIM technology is applied to the assembly production stage.
