The document outlines various types of Level of Development (LOD) in Building Information Modeling (BIM), including LOD 100 for concept design, LOD 200 for schematic design, LOD 300 for detailed design, LOD 400 for fabrication and assembly, and LOD 500 for as-built. It serves as a guide for understanding the progression of design stages in BIM. Additional information can be found on their website.
