BIMForum has released the Public Comment Draft of its 2024 Level of Development Specification (you can find it here www.bimforum.org/lod). The public comment period will close Monday, 09th December 2024 – after that they will resolve the comments and publish the Official 2024 version on or about 20th December 2024. This is an essential step in the yearly update of the Specification – please post thoughtful comments to here.
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.
The LOD Specification defines and illustrates characteristics of model elements of different building systems at different Levels of Development. This clear articulation allows model authors to define what their models can be relied on for, and allows downstream users to clearly understand the usability and the limitations of models they are receiving.
The intent of this Specification is to help explain the LOD framework and standardize its use so that it becomes more useful as a communication tool. It does not prescribe what Levels of Development are to be reached at what point in a project but leaves the specification of the model progression to the user of this document.
