- In this module, we’ll move our design proposals from Conceptual Design (LOD 100) to Schematic Design (LOD 200).
- In upcoming modules, we’ll continue to develop our designs — moving into Detailed Design (LOD 300).
BIM Level of Development (LOD)
The Level of Development (LOD) specification is a framework that enables practitioners in the AEC Industry to specify and articulate, with a high level of clarity, the content and reliability of Building Information Models (BIMs) at various stages in the design and construction process.
The LOD Framework addresses various issues faced by AEC professionals by providing an industry-developed standard to describe the state of development of various systems within a BIM. This standard enables consistency in communication and execution by facilitating the detailed definition of BIM milestones and deliverables.
How Our Design Process Maps to LOD
Level of Development | Class Modulles | Software Tools | What’s Included in the Model |
LOD 100
Conceptual Design | Module 2
Conceptual Design with Forma Site Design | Forma Site Design | A conceptual model where parameters like area, height, volume, location and orientation are defined. |
L0D 200
Schematic Design | Module 3
Schematic Design with Forma Building Design | Forma Building Design | A general model where elements are modeled with approximate quantities, size, shape, location and orientation. |
LOD 300
Detailed Design | Modules 4
Modeling Building Elements
Shell & Core
Module 5
Modeling Building Elements
Interiors
Documentation and Publishing
Module 6
Structural Systems
Module 7
Mechanical Systems
Module 8
Power & Electrical Systems | Revit
Forma Board | Accurate modeling where elements are defined with specific assemblies, precise quantity, size, shape, location and orientation. |
LOD 350
Coordination | Module 9
3D Coordination | Revit
Forma Model Coordination | More detail and elements that represent building elements interface with various building systems and other elements with clear graphics and written definitions. |
LOD 400
Fabrication
| Not covered in this class | Model elements are modeled as specific assemblies, with complete fabrication, assembly and detailed information in addition to precise quantity, size, shape, location and orientation. | |
LOD 500
As-Built | Not covered in this class | Elements are modeled as constructed assemblies for operations and maintenance. In addition to actual and accurate in size, shape, location, quantity and orientation. |
