During the pre-installation review, the field issue is that the project condition shows that frame must remain stable during erection. Which steel erection control is the best match?
Correct Answer
C) Use temporary bracing until frame stability
temporary bracing until frame stability best matches the stated condition. The other choices are real construction options in the same family, but they fit different field conditions.
Why This Is the Correct Answer
temporary bracing until frame stability best matches the stated condition. The other choices are real construction options in the same family, but they fit different field conditions.
Why the Other Options Are Wrong
Option A: Use remove bracing after first beam
Use remove bracing after first beam addresses a neighboring field issue, but not the condition or method control required for steel erection sequence.
Option B: Use load deck before frame is plumbed
Use load deck before frame is plumbed addresses a neighboring field issue, but not the condition or method control required for steel erection sequence.
Option D: Use release crane before stability is achieved
Use release crane before stability is achieved addresses a neighboring field issue, but not the condition or method control required for steel erection sequence.
