In the TYPE 1 designation 332, what does the digit 2 denote?

• A. Exterior curtain wall
• B. Void spaces
• C. Floor construction
• D. Columns, girders, and beams

Answer: (C)

In this TYPE 1 designation system, each digit points to a different building system, and the last digit identifies the floor construction. So in 332, the final 2 signals the floor construction—the floor slabs and their supporting members. This labeling helps you quickly locate details about the floor system on drawings, separate from exterior curtain walls, void spaces, or the columns and girders/beams, which would be indicated by other digits in the same scheme.
