Deepening design involves supplementing and refining bidding or original construction drawings during project implementation to make them executable on-site. This process is complex, requiring coordination across multiple disciplines, adherence to technical and regulatory standards, and a thorough understanding of materials and equipment. Deepening design is particularly challenging in large, complex construction projects where numerous systems and intricate layouts can cause equipment pipelines to clash with each other or with structural elements. Such conflicts complicate construction, reduce interior net height, lead to rework or waste, and may even pose safety risks.
Moreover, the construction industry often suffers from a lack of cross-industry standards and specifications, breaking the data chain from design to manufacturing. This results in collaboration difficulties and inefficiencies that hinder the industry’s industrialization. For example, the curtain wall industry requires a higher degree of customization for panels compared to traditional manufacturing. This customization varies not only between projects but sometimes even among panels within a single project, demanding flexible and rapid on-demand production. Additionally, with new materials, technologies, and evolving architectural aesthetics, curtain walls are becoming larger and more complex. These factors complicate on-site installation and assembly research and development. Poor management of delivery sequences and installation processes, or confusion over panel placement, can cause construction delays and resource waste.
To prevent these issues, traditional construction processes coordinate pipeline layouts across disciplines through comprehensive two-dimensional pipeline designs during deepening design. This typically involves overlaying 2D pipeline layouts from various specialties, establishing relative positions based on certain principles, determining pipeline elevations, and creating sectional drawings for critical areas. However, traditional 2D comprehensive pipeline design has limitations, which is why adopting BIM technology for three-dimensional pipeline design has become the preferred solution for managing layout challenges in large, complex buildings.
Advantages of BIM Technology in Deepening Design:
In traditional deepening design processes, system parameter reviews rely on 2D plans, which often differ significantly from the actual installed systems, leading to inaccurate calculations. Oversized systems increase construction costs and waste energy, while undersized systems risk malfunction. For large, complex projects, BIM technology offers clear benefits. A BIM model is a fully dimensional, information-rich 3D representation of the entire building. This modeling process uncovers many hidden design issues and serves as a comprehensive “3D review” tool. Compared to traditional 2D deepening design, BIM technology’s advantages include:
1. 3D Visualization and Accurate Positioning
BIM’s 3D visualization presents a realistic preview of the completed project before construction begins, making the design intuitive and clear. Models are created to real scale, including details often omitted in traditional drawings—such as pipeline insulation layers—revealing latent problems that might otherwise go unnoticed. Unlike isolated 2D floor plans, BIM models provide real-time correlation between plans and 3D views, enabling direct comparison with actual objects.
2. Collision Detection and Optimized Layout
Traditional 2D drawings often fail to fully reflect potential collisions between systems, disciplines, or components, and designers may overlook some conflicts. BIM’s collision detection capabilities allow for early identification of clashes during comprehensive pipeline design. This facilitates timely coordination among designers, owners, and consultants, significantly reducing on-site pipeline conflicts and rework during deepening design. As a result, BIM minimizes construction change orders, improves site productivity, and reduces cost overruns and schedule delays caused by coordination issues.
3. Equipment Parameter Review and Calculation
During electromechanical system installation, pipeline routes may be adjusted due to coordinated design or finishing touches, altering lengths and bends and impacting original system parameters. BIM software automates complex calculations once the electromechanical model is created, updating results instantly when design changes occur. This provides accurate data for selecting equipment parameters.
Yingda BIM offers a unified collaborative deepening design platform that streamlines cooperation among different units and specialties. This platform enables parallel collaboration during deepening design, allowing construction teams to apply their on-site expertise and coordinate closely with design units. Together, they ensure timely, accurate communication of detailed construction drawings that meet on-site requirements. This collaboration reduces errors, losses, and rework during construction, accelerating project completion and lowering costs for owners.
