Why Level of Development (LOD) Matters in BIM Projects
Level of Development (LOD) is a key part of Building Information Modeling (BIM) that defines how detailed and reliable a model should be at each stage of a project. Understanding LOD helps architects, engineers, contractors, and owners communicate clearly, reduce misunderstandings, and improve project coordination. This article explains the different LOD levels, why they matter, and how using the right LOD supports accurate planning, clash detection, cost estimation, construction, and facility management while minimizing rework and project risks.
