Detaillierungsgrads

Detaillierungsgrads is a German term used to describe the level of detail, granularity, and fidelity of a model, document, or design. It encompasses geometry, attributes, and relationships, and indicates how much information is provided at a given stage. The concept helps communicate expectations about precision and completeness in a project.

In engineering, architecture, manufacturing, and software development, the Detaillierungsgrad is deliberately increased as a project progresses—from high-level concepts to detailed specifications and fabrication-ready data. It supports planning, cost estimation, coordination among stakeholders, and procurement. Clear management of the Detaillierungsgrad reduces rework and inconsistencies between disciplines.

In Building Information Modeling (BIM) and CAD work, the related idea is often described by levels of detail (LOD). Common practice uses stages such as LOD 100 through LOD 500 to describe the expected geometry, quantities, and non-graphical information. Examples include LOD 100 (symbolic massing), LOD 200 (approximate geometry and quantities), LOD 300 (precise geometry), LOD 350 (interfaces and connections), LOD 400 (fabrication-level drawings), and LOD 500 (as-built data). The exact definitions vary by organization and region, and many projects adopt customized scales.

Challenges include definition discrepancies across industries and projects, where the same term can mean different criteria. Success depends on clear definitions in project specifications and exchange formats, as well as robust information-management processes. Related concepts include Level of Detail and Level of Information as used in BIM and ISO 19650 standards.
