Which method involves completely assembling the tower lying on the ground and then lifting as one unit onto its footers or anchors?

• A. Piece by piece method
• B. Section Method
• C. Completely assembled lying on the ground and then lifted as one unit onto its footers or anchors
• D. All of the above

Answer: (C)

The concept tested is tower erection by choosing how the entire structure is brought into position. The best answer describes assembling the entire tower on the ground and then lifting it as a single unit onto its footers or anchors. This method minimizes on-site, at-height assembly by having all components connected before the lift, provided you have a crane with enough capacity and solid ground to support the lift. It’s different from building the tower piece by piece at height or lifting larger sections progressively; those approaches require multiple lifts and more rigging near or at the structure. Therefore, lifting the fully pre-assembled tower in one go is the correct description.
