In platform framing, when is framing typically completed?

• A. All floors at once
• B. One floor at a time
• C. During the foundation stage
• D. After the walls are erected

Answer: (B)

Platform framing is built floor by floor. Each story is started on its own deck or platform, and the wall framing for that level is erected on that platform. Once that level’s walls are in place, the next floor platform is installed and the process repeats up the height. This stepwise approach means the overall framing is completed one floor at a time, not all at once. Framing happens after the foundation stage, and it isn’t finished only after all the walls for the entire building are up, since work proceeds level by level.
