Download LOD 2018 Specification draft

This summer, the BIMForum released the 2018 Public Comment draft of its Level of Development (LOD) Specification. The previous version was introduced way back in 2016 and is also available for download from the BIMForum website.
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.
This year’s update includes:
  • Part I – Added content (Escalators)
  • Part II – Attribute tabs have been modified
