During the pre-installation review, the field issue is that the work should be released only if the team addresses that deep formed concrete must be consolidated inside the form. Which concrete tool is the best match?
Correct Answer
D) Coordinate internal concrete vibrator
internal concrete vibrator 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
internal concrete vibrator 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: Coordinate vibrating screed
Coordinate vibrating screed addresses a neighboring field issue, but not the condition or method control required for concrete tool selection.
Option B: Coordinate power trowel
Coordinate power trowel addresses a neighboring field issue, but not the condition or method control required for concrete tool selection.
Option C: Equipment choice: Coordinate external form vibrator
Equipment choice: Coordinate external form vibrator addresses a neighboring field issue, but not the condition or method control required for concrete tool selection.

Reference Hint
Open-book path: tab Principles and Practices of Commercial Construction, 10th Edition to Concrete tools; internal vibrators for consolidation; verify the construction method, material selection, equipment choice, or work sequence that fits the field condition.
