What does LOD stand for in the context of granularity?

In the context of granularity within Building Information Modeling (BIM), LOD stands for Level of Detail. This term is critical for communicating the amount of detail that is included within the model at various stages of a project. The concept of LOD provides a framework for understanding how detailed various components of a BIM model should be, allowing for better coordination among different stakeholders such as architects, engineers, and contractors.

Each level of detail corresponds to a specific phase of the project and helps in clarifying expectations for what information is to be conveyed in the model. For instance, earlier stages might focus on broader concepts and spatial relationships, while later stages would include more precise information such as materials and specific construction elements. Understanding LOD is essential for effective project planning and execution, ensuring that all team members have the appropriate level of detail needed for their tasks at any given time in the project lifecycle.
