REVIT | Levels of Development in REVIT BIM |Building Information Modeling (BIM)
The different levels of development in REVIT BIM (LOD) in REVIT and BIM. LOD 100 - LOD 200 - LOD 300 - LOD 400 specifications.
LOD 100 BIM GUIDE
LOD 100: This represents the most basic level of development. At LOD 100, the model elements are represented in a very conceptual form. They might resemble generic placeholders to represent the approximate location, size, and shape of the building components. These placeholders provide a rough idea of the overall building footprint and layout.
LOD 100 BIM EXAMPLE
LOD 200 BIM GUIDE
LOD 200: At this level, the model elements become more defined. They start to resemble actual building components with approximate quantities, shapes, sizes, and locations. However, they lack specific detail and are still generic in nature. LOD 200 models are typically used for early design and conceptualization stages where more detailed information is not yet available.
LOD 200 BIM EXAMPLE
LOD 300 BIM GUIDE
LOD 300: This level represents a significant advancement in detail. At LOD 300, the model elements are developed to include accurate geometry, quantity, size, shape, location, and orientation. They may also include detailed information about how different elements interact with each other. LOD 300 models are commonly used for detailed design and coordination purposes, where precise information is required for accurate visualization and analysis.
LOD 300 BIM EXAMPLE
LOD 400 BIM GUIDE
LOD 400: LOD 400 represents an even higher level of development. At this stage, the model elements are not only geometrically accurate but also include specific information about fabrication, assembly, and construction details. LOD 400 models may include information about connections, tolerances, materials, and finishes, enabling contractors and fabricators to use the model for procurement, fabrication, and construction planning.
LOD 400 BIM EXAMPLE
LOD400 WITHOUT MEP.
