Understanding Levels of Development (LOD) in Scan-to-BIM

In the world of architecture, engineering, and construction, precise measurements are essential for reducing errors, optimizing workflows, and ensuring project success. This is where scan-to-BIM technology comes into play—leveraging 3D scans to create highly accurate digital representations of physical spaces. However, not all projects require the same degree of detail. The industry uses a standardized system known as Levels of Development (LOD) to communicate the precision and amount of information included in a Building Information Modeling (BIM) model.

The concept of LOD in scan-to-BIM is derived from guidelines established by organizations like the American Institute of Architects (AIA) LOD Specification and the BIMForum LOD Specification. These standards help project stakeholders align their expectations for detail, cost, and timelines.

Selecting the appropriate LOD for your scan-to-BIM project is essential to balancing accuracy, time, and budget. For instance, smaller renovation projects might only require LOD 200 or 300, while new builds or complex commercial structures may benefit from the detailed precision of LOD 400 or 500. By leveraging 3D scanning technology, firms can efficiently produce accurate models tailored to their project’s specific needs.

At TechServ, we use the Matterport PRO3 camera to produce 2D and 3D models at LOD 200 with an impressive 0.2% accuracy, providing reliable data that is highly useful for design, planning, and renovation projects.
