When utilizing BIM technology for pre-embedded structural components and reserved structural openings, the main considerations include:
- Industrial construction should be distinctive yet harmonious with the overall architectural style;
- During the planning phase, focus on investment cost control throughout the entire process;
- Maintain overall control of process flow, component costs, production cycles, and production coordination;
- During construction, closely manage the schedule, cost control, and coordination between upstream and downstream production;
- Cutting bricks is strictly prohibited for prefabricated components.
When using BIM models for design segmentation, all relevant application teams’ collaboration needs must be taken into account. Experienced designers should establish segmentation strategies early in the BIM model application to avoid isolated, single-user files and prevent reactive model splitting. Reusable “3D component drawings” can significantly enhance production efficiency. The goal is to produce pre-component processing drawings within the project production cycle, thereby shortening the project timeline and improving overall efficiency.
The comprehensive BIM process integrates design principles, and BIM prefabricated component models can be categorized as straight wall panels, L-shaped wall panels, interior wall panels, parapet walls, balcony panels, air conditioning panels, PCF panels, and stairs.
When conducting construction and detailed design of components, special attention should be given to:
- The design must consider the relationship between the tower crane’s rotation radius and the weight of prefabricated components, which can be simulated using BIM models;
- Balance construction efficiency with serialization and standardization;
- Coordinate and unify the production and construction plans;
- Exercise caution in designing complex components due to potentially low construction efficiency.
The detailed design of prefabricated components is based on a three-dimensional design model. This involves disassembling components, accurately calculating their volume and weight, guiding the calculation of prefabrication and assembly rates, and creating various prefabricated component models. The design deepens on the prefabricated component model by arranging steel bars and various embedded parts, directly generating the drawings required for component production, and precisely calculating the specifications, lengths, quantities, and models of steel bars and embedded parts.
