In a large, heavy lattice tower project on rough ground, which assembly method is appropriate?

• A. Piece by piece method: tower built from the ground up one piece at a time
• B. Section Method: sections assembled on the ground, then hoisted
• C. Completely assembled lying on the ground and lifted as one unit
• D. All of the above

Answer: (A)

Building a large, heavy lattice tower on rough ground is best done piece by piece, starting from the foundation and adding segments upward. This approach keeps loads smaller and more controllable, reduces the need for a perfectly level, strong surface for a single lift, and lets you use smaller cranes or winches with temporary bracing to maintain plumb as you go. Lifting large sections or the entire tower as a single unit demands much more stable ground and a very high lifting capacity, which isn’t practical on rough terrain. Assembling sections on the ground and then hoisting them also presents challenges on uneven ground and requires substantial space and equipment. So the piece-by-piece method is the most appropriate choice here.
