In lattice tower construction, which method involves assembling sections on the ground and then hoisting them into place?

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

Answer: (B)

The main idea here is prefabrication and how sections are raised during lattice tower erection. The method that fits the description—assembling sections on the ground and then hoisting them into place—is the Section Method. Building sections on the ground lets you preassemble and check alignment before lifting, which speeds up the erection process and improves safety. In contrast, the piece-by-piece approach involves assembling and tying together members at height, not preassembled sections on the ground, and lifting a completely assembled tower in one piece is typically impractical due to weight and crane limits. So the described approach is the Section Method.
