My next series of Blogs are going to be about BIM Level of Development as outlined by the AIA. Even though it's American standards (some of us are not from the States) they have done a lot of research on this subject so it's defiantly worth taking a look and modifying it to your specific needs.
The reason I'll discuss this subject is that as we use Revit more and more we at risk of Over Modeling our model. Over modeling will reduce your efficiency of your workflow as well as the efficiency of your model. We work hard to make Revit work for us but we are in danger of getting sucked into the Void of Over Modeling.... Du Du Du Daaaa! (dramatic sound effects !!)
Here is a brief explanation of Level of Development (LOD):
Level of Development: Levels of Development (LOD) describe the level of completeness to which a Model Element is developed.
How much we model at each stage is broken down into 5 basic levels.
LOD 100 - Conceptual Design, creating mass models for the concept stage. Volumes, height, location and orientation. Basic building analysis etc.
LOD 200 - Schematic Design/Design Development. developing the general assemblies, etc. A basis for the working drawings.
LOD 300 - Working Drawings, construction documentation, building analysis etc.
LOD 400 - typically not achieved by the Designer or Architect as this level of detail is typically required by fabricators. for example manufacturers of RTU's would detail their components at this level for fabrication.
LOD 500 - As Built Model. the final level of detail that represents the true building. Ideally used for building operations and maintenance.
Model Elements: Model Elements represent building component, system or assemblies within a building or building site.
Model Element Author: The party responsible for developing the content of the specific model. to the Level of Detail required by the particular phase of the project.
Model User: this refers to any authorized individual or company who may use the model. for example some one doing a quantity take off, scheduling, analysis?
I'll go over how each of these LOD's can be used in my next Blog.
