Fabrication and Level-Of-Development: When to Draw the Line(and Where to Model It) was one of the 12 classes I attended at Autodesk University 2015.

Will Ikerd, PE highlighted four new BIM Level-Of-Development (LOD) topics from the team authoring the BIMFORUM LOD Specifications:

• New 2015 LOD Spec Available for download. (see below)
• New LOD 350 Specification
• Definition of when to specify and recommended use of LOD 350
• New Course Certification Program: Certificate of Detailing in BIM (CD-BIM)

--- Taking the Mystery Out of BIM | CM-BIM Classes ---

This presentation will provide an in-depth discussion of fabrication and Level Of Development (LOD) from the 2015 Associated General Contractors (AGC) Building Information Modeling (BIM) Forum LOD Specification.

It will address model elements at the different stages in a building lifecycle: design, construction, and ownership. The framework of the discussion will consider the LOD Specification that defines models on a scale of 100 to 500 with a particular focus of LOD 350, which the speaker originally authored and introduced to the LOD Specification committee.

The content will discuss how architects, mechanical engineers, construction managers, subcontractors, and fabricators use structural element models. This will demonstrate how you can use the newly issued LOD Specification to define team expectations of what should be modeled. We will show practical examples of model detail issues, along with effective approaches to resolve the challenges using the LOD Specification as an early BIM planning tool.
