We are back on track! One more post of BIM Tree Chimpanzee series and one more workflow for our blog readers and followers.
Today, I would like to discuss BIM development by going through BIM stages. Hopefully most of BIM users are familiar with LOD notion, but for those who are not – I will shortly introduce this term. As one of the most contributing organizations in BIM development, buildingSMART international provides such description of LOD: “The Level of Development (LOD) Specification is a reference 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”. LOD is divided into 6 stages that comply with the standard: LOD 100 – Concept (or Pre-Design), LOD 200 – Design Development (or Schematic Design), LOD 300 – Documentation (or Design Development), LOD 350 – Construction Documentation, LOD 400 – Construction Stage and the last one – LOD 500 – As-Built model.
