By BIMForum on November 03, 2015

Washington, DC, November 3, 2015 —  The BIMForum today announced the publication of the 2015 version of the Level of Development (LOD) Specification for Building Information Models. Anyone may download the specification for free here.

The LOD Specification is a reference standard that enables practitioners in the AEC industry to specify and articulate with a high level of clarity the content and reliability of BIM data at various stages in the design and construction process. It defines and illustrates characteristics of model elements from different building systems at different levels of development.

What’s new in the 2015 version:

•          More graphic illustrations for various building systems

•           The geometric specifications are now known as “Part A”

•           A new document, called “Part B,” begins to address development of non-geometric information

BIMForum is a not-for-profit organization whose mission is to facilitate and accelerate the adoption of building information modeling (BIM) in the AEC industry. Co-sponsored by the Associated General Contractors of America (AGC) and the American Institute of Architects (AIA), BIMForum seeks to lead by example and synchronize with counterparts in all sectors of the industry to jointly develop best practice for virtual design and construction.
