BIM Technology enables pre-construction assessments of building projects through construction simulation features, often referred to as a “rehearsal.” This process helps identify design flaws and construction challenges early on. While many issues can be detected during simulation, they are usually insufficient to fully guide construction operations or meet the actual needs of owners. Therefore, a secondary process called deepening design is necessary. Here, we will explore the benefits of BIM in deepening design.
Benefits of BIM in Deepening Design: 3D Visualization and Precise Positioning
Traditional 2D floor plans often require coordinating multiple drawings to understand the detailed location and structure of components, which can be unintuitive and time-consuming. This approach limits the visual range, increases workload, and reduces accuracy. By contrast, BIM technology allows the creation of a 3D visualization model based on BIM concepts, presenting the entire project clearly and intuitively to all stakeholders. Even owners without professional expertise can easily understand the visualized 3D model, greatly improving communication among all parties involved.
Moreover, the BIM model incorporates object-oriented and parametric concepts, integrating real data for every component within the building project. It highlights often overlooked elements in traditional drawings—such as insulation layers—enabling all parties to consider these hidden or difficult-to-detect issues during design. This helps address deep-seated risks before construction begins.
Benefits of BIM in Deepening Design II: Collision Detection and Efficient Layout
With traditional 2D drawings, even during deepening design, it is challenging to detect clashes between different disciplines. Designers must rely heavily on spatial imagination and experience, which can lead to oversight and errors. This often results in frequent design changes and increased costs. BIM’s collision detection feature automatically identifies conflicts both within and across disciplines during the design phase. It generates detailed inspection reports that allow project participants to communicate and coordinate efficiently, reducing design changes and construction rework. This not only enhances work efficiency but also lowers extra costs and shortens the construction timeline.
The Third Benefit of BIM in Deepening Design: Equipment Parameter Review and Calculation
In traditional 2D deepening design, equipment parameter reviews are primarily based on plan views. However, frequent changes in the initial design often lead to adjustments in the drawings, causing discrepancies between calculations and actual conditions, which can disrupt workflow. BIM technology overcomes this by enabling parameterized and editable models. Unlike static 2D drawings, BIM models maintain linked relationships among components. A simple mouse click allows the software to automatically calculate and generate reports. When the model is modified, calculations are updated accordingly, ensuring accurate equipment parameter reviews and supporting informed equipment selection.
These are some of the key benefits of BIM in deepening design. In reality, BIM offers far more advantages during construction. I encourage everyone to share their experiences and insights so we can learn and improve together.
