In the UniFormat examples, what does the code B30 correspond to?

• A. Roofing
• B. Exterior Doors
• C. Field Orders
• D. Supplemental Instructions

Answer: (A)

In UniFormat, each element is identified by a code that combines a broad category (represented by a letter) with a specific item (represented by a number). The code B30 is assigned to Roofing in the standard examples, so this label groups roofing-related components—like roof coverings, insulation, flashing, and related assemblies—under one code. This systematic labeling helps organize project content so roof systems have a single, consistent place in estimates, drawings, and specifications. Exterior Doors would be classified under a different code within the relevant category, since it’s a distinct building element. Field Orders and Supplemental Instructions are administrative/document items rather than physical building elements, so they don’t map to a construction element code like B30.
