LOD (Levels of Detail) is reception in creating digital models with different levels of detail. For construction projects, LOD requires a lot of detail, with detailed visualization of premises, engineering systems, etc.
In construction projects, there are several basic levels of LOD:
LOD 100 - the minimum level of model development. Conditional object with basic identification detail.
LOD 200 - a conditional object with the minimum necessary for making informed economic decisions development of information.
LOD 300 - project model with specific and precise values of shape, position and main attributes.
LOD 400 - a high level of development with maximum detailed graphical representation and information in properties. It can be said,
, that it is LOD 300 + detail of nodal connections, together with data on manufacturing, cost and installation.
LOD 500 = LOD 400 + execution documentation and performance characteristics.
