What is Level of Development (LOD)?
Learn which LOD each BIMIT setting is modeled to, what that includes and excludes, and why field verification still applies.
Knowing the Level of Development (LOD) that BIMIT delivers helps you set the right expectations for your project. BIMIT comes in three settings, each built to its own LOD, from LOD100 at BIMIT 100 to LOD300 at BIMIT 300. None of them is a substitute for construction-grade documentation or field verification.
LOD by setting
Each BIMIT setting is designed to achieve the Level of Development (LOD) in its name, as defined by the BIM Forum and BIM International: BIMIT 100 is built to LOD100, BIMIT 200 to LOD200 and BIMIT 300 to LOD300. How each setting draws its elements, and what each one is built for, is covered in "Choosing a setting".
- Element accuracy. How closely elements are placed and sized against the scan depends on the setting, and is covered in Accuracy and Level of Development.
- No materials or specifications. The model does not include material information or construction details, and it does not claim construction-grade accuracy.
Not a guide for construction
Whichever setting you order, BIMIT gives you a visual representation of the building, but it should not be used as a definitive guide for construction.
Because point cloud registration from devices like the Matterport Pro2 or Leica BLK360 has inherent accuracy limits, BIMIT should not be treated as construction-grade.
Field verification still applies
BIMIT does not replace the industry-standard practice of field verification. Licensed design, engineering, and construction professionals should always verify in the field, regardless of model accuracy.
BIMIT is a valuable tool in the design and planning phases — understanding its scope and limitations is key to using it well.
