Level of Development - LOD400

Level of Development - LOD400 is a classification within the BIM (Building Information Modeling) framework that defines the level of detail and reliability of a model's elements. At this stage, model elements are highly detailed and include precise fabrication, assembly, and installation information.

                              Applications

  • Fabrication & Prefabrication – The model includes manufacturer-specific components, ready for direct fabrication of structural, MEP, and architectural elements.
  • Construction Execution – Used for site installation, ensuring all elements fit precisely as designed.
  • Advanced Clash Detection & Coordination – Prevents conflicts between structural, MEP, and architectural systems before fabrication begins.
  • MEP & Structural Shop Drawings – Generates detailed shop drawings for ducts, pipes, steel, concrete reinforcements, and other prefabricated components.
  • Quantity Takeoffs & Procurement – Provides highly accurate material counts, reducing wastage and optimizing procurement.
  • 4D Scheduling & Construction Sequencing – Enhances project planning by linking model components to the construction timeline (BIM 4D).
  • Digital Twin for Quality Control – Enables precise verification of installed elements against the model using laser scanning and reality capture technologies.
