The application of BIM in the design stage

During the design phase, BIM can help architects and design teams better visualize and understand design solutions. Through BIM models, designers can simulate and analyze the effects, performance, and costs of different design options to make more informed decisions. In addition, BIM can integrate information from different design disciplines into a single platform, enabling cross-professional collaboration and conflict detection, thereby reducing the possibility of design errors and rework.

1. BIM visual modeling

Design and BIM modeling are parallel, through the analysis and discussion of drawings, according to the 2D design drawings, BIM technology is used to apply related software to create architectural, structural and mechanical and electrical professional models of the project. Through the establishment of the three-dimensional model, the scheme can have an intuitive performance effect and achieve "what you see is what you get".

2. Coordination of various specialties
Through the integration of resources of each specialty, BIM comprehensively sorts out the floor drawings of each specialty through three-dimensional modeling, guides each specialty, adjusts according to the problems of all parties reflected in the BIM model, carries out timely tuning work, realizes project information sharing, better meets engineering needs, and improves design quality.

3. Design optimization
After the BIM model is comprehensively adjusted and optimized for pipelines, the selected equipment is considered to be optimized and selected, focusing on the resistance check of water pumps and fans, and guiding equipment selection, routing optimization, valve optimization and connection optimization. Through the resistance check of the water system pipeline, the optimal selection of the water pump is recommended, and the pipeline components are optimized.

Through the resistance calculation of the air duct system, the return air duct is optimized to match the fan reasonably.

4. BIM deepening drawings
After BIM deepening, the two-dimensional deepening drawings can be directly output to each specialty, and the model corresponds to the drawings one by one, guiding the subsequent construction according to the model and the drawing.
