In the TYPE 1 designation 332, what does the second digit 3 denote?

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

Answer: (B)

In this coding system, each digit in a Type 1 designation points to a different building element, guiding how fire safety and construction details are organized. The second digit is the one that identifies the structural frame—columns, girders, and beams. That’s why the middle digit being 3 signals that category. Other features like floor construction, exterior curtain walls, and void spaces are represented by other digits in the designation, not the second one. So the second digit denotes the structural frame components, making it the best interpretation for that position.
