Architectural Designing Modelling Detailing

Conceptual Design

• LOD 100 represents the initial stage of a BIM model.
• It includes basic massing and volume information.
• Typically used during the conceptual design phase to provide a rough idea of the building's shape and size.

Schematic Design

• LOD 200 builds upon LOD 100 by adding more detail to the BIM model.
• It includes approximate quantities, sizes, shapes, and locations of major building components.
• Used during the schematic design phase to refine the project's design.

Detailed Design

• LOD 300 is a highly detailed model used during the design development phase.
• It includes precise geometry and information about individual building components.
• Used for coordination and analysis, making it valuable for contractors and engineers.

Construction Documentation

• LOD 350 adds more information to LOD 300, primarily focusing on construction documentation.
• It includes specific assembly details, materials, and quantities.
• Used to generate accurate construction documents for contractors.

Fabrication & Assembly

• LOD 400 is crucial for fabrication and assembly of building components.
• It provides detailed information about each element, including fabrication, assembly, and installation instructions.
• Essential for off-site prefabrication and accurate construction.

As-Built

• LOD 500 represents the most comprehensive and accurate BIM model.
• It reflects the actual, as-built condition of the building.
• Used for facility management and maintenance, providing data for ongoing operations.
