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.
