The presentation will provide an in-depth discussion of fabrication and the 2016 AGC BIM Forum Level of Development (LOD) Specification featuring one of the specifications’ authors. 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 fabrication focus will provide practical examples of LOD from 300 to 350 to 400 for structural steel, concrete, cold-formed metal, enclosures, and MEP (mechanical, electrical, and plumbing). We will discuss how architects, mechanical engineers, construction managers, subcontractors, and fabricators use structural element models. This will demonstrate how to use LOD to define team expectations of what should be modeled. We will show practical examples of model detail issues, along with effective approaches to resolving the challenges using the LOD Specification as an early Building Information Modeling (BIM) planning tool. This session features Navisworks Manage, Navisworks Manage, and Revit. AIA Approved
