If tiebacks cannot be rigged straight back, what is a viable option?

• A. Install a second tieback in the opposite direction
• B. Move parapet
• C. Use a longer tieback
• D. Ignore tiebacks

Answer: (A)

When tiebacks can’t be rigged straight back, the practical approach is to install a second tieback in the opposite direction to create a stable, triangulated support. Tiebacks counter earth pressures and keep the sheeting from moving; if the direct-back path isn’t feasible, adding a second tieback in the opposite direction forms a triangular load path that distributes forces and maintains stabilization. This keeps the wall oriented and reduces bending or movement that could occur if you tried to force a straight-back arrangement. Moving the parapet is a larger modification that isn’t a typical solution to tieback geometry. Using a longer tieback doesn’t address the obstruction to back-anchoring and can still fail to achieve the proper load path. Ignoring tiebacks is unsafe and unacceptable.
