Level of Development (BIM – LOD):

BIM’s LOD defines how much and what type of information is included in the model. It is standardized as below to maintain harmony internationally.

LOD 100 – Conceptual Design

LOD 200 – Schematic Design

LOD 300 – Detailed Design

LOD 350 – Construction Documentation

LOD 400 – Fabrication & Assembly

LOD 500 – As-Built

LOD 100 – Conceptual Design

This model is developed to represent the information on basic level like Location, Orientation, Approximate Area, Height and Space allocation.

LOD 200 – Schematic Design

General models where elements are modeled with approximate quantities, shape, size and location.

LOD 300 – Detailed Design

Shop drawings and accurate modeling where elements are defined with specific assemblies, precise quantity, shape, size, and location.

LOD 350 – Construction Documentation

It has model details and elements that represent how building elements interface with various systems and other building elements with written definitions and graphics.

LOD 400 – Fabrication & Assembly

Model elements are modeled as specific assemblies, with complete fabrication, and detailing information in addition to precise quantity, shape, size and location. Even the CNC-Codes and Other Codes needed for machines are provided.

LOD 500 – As-Built

Elements are modeled as constructed assemblies for Maintenance and operations. In addition to actual and accurate in shape, size, location, and quantity. Example: Modelling done out of Laser Scan.
