What is LOD (level of development) in BIM?

Also called: LOD

Definition

LOD (level of development) describes how complete and reliable the geometry and information of a BIM element is at a given project stage, usually on a scale from LOD 100 to LOD 500. Agreeing LOD at each stage tells everyone what a model can be relied on for, such as early cost estimates or construction coordination.

Why does LOD (level of development) in BIM matter for architects, engineers and contractors in India?

Agreeing LOD at each stage tells everyone what a model can be relied on for, such as early cost estimates or construction coordination. It also prevents teams from over-modelling too early.

What is an example of LOD (level of development) in BIM?

At concept stage walls are modelled at LOD 200 for area checks; before tender they are developed to LOD 350 so services coordination is reliable.
