Detailed analysis of BIM deepening design!

Deepening design refers to the refinement, supplementation and improvement of the drawings on the basis of the blueprint provided by the owner's design unit in combination with the professional drawings and the construction site situation, so that they can meet the technical requirements of the design unit, meet the industry design specifications and construction specifications, and pass the drawing review. The deepened design drawings can directly guide the on-site construction to ensure that the final effect is beautiful and reasonable.

Traditional Deepening Design & BIM Deepening DesignIn traditional deepening design, due to the limitations of two-dimensional design software, small amount of information, poor visual ability, etc., even if designers have strong spatial imagination ability and professional knowledge, errors, omissions, collisions and other situations will inevitably occur in actual engineering. And in the process of deepening the downward flow of design drawings, it is often necessary to cooperate with the explanation, supplemented by hand-drawn explanation. Facts have proved that the use of 2D design software for detailed design is not only inefficient, but also difficult to ensure accuracy. The BIM model established by digital technology can not only present a virtual model consistent with reality, but also contain a building engineering information database that is consistent with the actual situation (geometric information, professional attributes and status information of building components, and state information of non-component objects), which effectively solves a variety of problems often encountered in the process of two-dimensional deepening and makes the design visual.

BIM Deepening Design Classification: BIM-based detailed design can be divided into design deepening and on-site deepening according to the process node, and professional deepening design and comprehensive deepening design according to the type of specialty.

1. Follow the process node1) Design deepening: The design deepening work is mainly to maintain the rationality of the design, and the work content generally includes collision detection, net height analysis, comprehensive layout of pipelines, etc. 2) On-site deepening: The main purpose of on-site deepening is to make the construction drawings after the deepening design be combined with the actual situation of the construction site, reduce the difficulty of construction, and ensure the smooth construction of the construction party. The on-site deepening content includes the refinement of construction drawings, construction material statistics, construction budget, etc. 2. According to the type of major1) Professional deepening design: Professional deepening design is generally carried out on the professional BIM model provided by the construction unit. The deepening content generally includes the detailed design of civil structure, steel structure, curtain wall, mechanical and electrical (HVAC, water supply and drainage, fire protection, strong electricity, weak electricity, etc.), fine decoration detailed design, landscape greening detailed design, etc.

2.Comprehensive deepening design: comprehensive deepening design is generally carried out on the overall model provided by the construction unit, and the comprehensive deepening design needs to integrate, coordinate, revise and check the preliminary results of the professional deepening design to form a comprehensive floor plan and comprehensive pipeline diagram, and the focus of the comprehensive deepening design is to maintain the coordination and consistency of the professional drawings.
