Traditionally, collision detection in design involved printing out drawings from various disciplines, stacking them to align grids and elevations, or manually inspecting common reference points. This approach is not only labor-intensive but also highly inefficient.
With the rise of computer technology, numerous software tools now assist in checking electronic drawings. However, these still require manual operation by users. While effective for conventional buildings, this method often leads to errors when applied to complex structures. BIM technology addresses this challenge by enabling three-dimensional information modeling and collision detection within 3D models, offering high accuracy. This advantage is especially evident in complex building models, where BIM’s three-dimensional simulation capabilities significantly improve collision detection.
Using the Revit platform, models for the three disciplines—structural, architectural, and mechanical—have been created. These building information models are shared on a common platform, linking building and mechanical models to facilitate collaboration based on the structural model. Once all models are integrated, collision checks are performed to identify and resolve conflicts or clashes.
When linking the structural model with building and mechanical models, it is crucial to select the “automatic – origin to origin” positioning option, as all discipline models in this office building share the same grid and elevation. Within the integrated model, collision checks can be initiated by clicking “Collision Check” under the “Collaboration” tab. This process allows for the detection of clashes between components such as structural columns, beams, and various pipelines.
