INTRO In Building Information Modeling (BIM), LOD stands for Level of Development. It is a framework used to define the level of detail and reliability of BIM elements throughout a project's lifecycle. LOD helps project stakeholders understand the degree of accuracy and the extent to which elements have been developed. Lod in bim 2
The 6 levels of detail in bim Lod in bim 3 LOD 100 LOD 200 LOD 300 LOD 400 LOD 500 LOD 600
LOD 100 - CONCEPTUAL Lod in bim 4 Basic Characteristics: Represents the overall design intent. Simplistic forms indicating building massing. Visualization: Often includes 2D drawings alongside 3D models. Collaboration: Initial discussions among stakeholders to align visions. Use Cases: Site selection and feasibility studies. High-level project budgeting and scheduling.
LOD 200 –APPROXIMATE GEOMETRY Lod in bim 5 Basic Characteristics: More refined shapes and sizes for major elements. Generic representations of systems (e.g., HVAC, plumbing). Visualization: 3D models start to represent approximate dimensions. Collaboration: Enhanced team interactions for design options. Use Cases: Design iterations and preliminary design reviews. Early coordination between different disciplines.
LOD 300 –PRECISE GEOMETRY Lod in bim 6 Basic Characteristics: - Detailed representations of architectural, structural, and MEP elements. - Includes actual materials and specifications.- Visualization: Models allow for realistic renderings and clash detection.- Collaboration: Increased detail fosters improved collaboration among disciplines. Use Cases: - Production of construction documents and shop drawings. - Quantity take-offs and more accurate cost estimates.
LOD 400 - FABRICATION Lod in bim 7 Basic Characteristics: Model reflects the built project with all changes documented. Incorporates any alterations made during construction. Visualization: Represents actual site conditions and configurations. Collaboration: Serves as a historical record for all stakeholders.- Use Cases: Post-construction documentation for maintenance. Assists in future renovations or expansions.
LOD 500- AS BUILT Lod in bim 8 Basic Characteristics: Model reflects the built project with all changes documented. Incorporates any alterations made during construction.- Visualization: Represents actual site conditions and configurations. Collaboration: Serves as a historical record for all stakeholders. Use Cases: Post-construction documentation for maintenance. Assists in future renovations or expansions. LOD 600- OPERATIONS Basic Characteristics: Integrates operational data and lifecycle information. Includes maintenance schedules, warranties, and contact information.- Visualization: Model used for facilities management systems. Collaboration: Supports ongoing collaboration with facility management teams. Use Cases: Streamlines operations, maintenance, and asset management. Facilitates performance monitoring and sustainability efforts.
SUMMARY Presentation Title 9 Benefits of LOD: Improves clarity and communication among project stakeholders. Helps in managing expectations and project outcomes. Transition between LODs: Each level builds on the previous one, enhancing detail and complexity Standards and Guidelines: Various organizations provide guidelines (e.g., AIA, buildingSMART ) to standardize LOD definitions. Impact on Project Delivery: Clear LOD definitions lead to more efficient project delivery and reduced errors.
