Questions Asked in BIM Modelling Interview
Q 1. Explain the difference between Level of Detail (LOD) 100, 200, 300, and 400 in BIM.
Levels of Detail (LOD) in BIM are a crucial way to define the level of geometric and informational completeness of a building element at different project stages. Think of it like building a LEGO castle: you start with a simple outline (LOD 100), then add more detail (LOD 200, 300), and finally, the intricate final details (LOD 400).
- LOD 100: This represents the schematic design phase. The model shows the overall size, shape, and location of elements. Think of it as a rough sketch—enough to understand the building’s massing and spatial relationships. Details like window types or specific materials are not included. Example: A simple rectangular box representing a building.
- LOD 200: In this stage, the model includes major building components, like walls, floors, and roofs, with basic dimensions and placement. Specific systems like HVAC or plumbing are not yet detailed. Think of it as the structure without any interior finishing. Example: Walls and floors are accurately positioned, with rough openings for doors and windows.
- LOD 300: This level includes more refined geometry and components. It incorporates detailed systems (MEP), specific materials, and precise openings. It’s like adding the interior walls, fixtures, and finishes to the LEGO castle. Example: Accurate representation of door and window types, specific material assignments, and placement of major MEP elements.
- LOD 400: This is the ‘as-built’ stage. The model shows the completed building with precise information and detailed components, including fabrication data and as-built information. Think of it as the fully finished, meticulously detailed LEGO castle. Example: The model includes precise dimensions, manufacturer-specific details for every component, and even the specific location of electrical outlets.
Understanding LODs is crucial for coordinating work across disciplines and efficiently managing the BIM project lifecycle.
Q 2. Describe your experience with clash detection and resolution in BIM projects.
