If tiebacks are angled, what must be installed?

• A. A swivel anchor
• B. No additional tieback
• C. A third tieback in same direction
• D. A second tieback opposite direction

Answer: (D)

Angled tiebacks create a horizontal component of pull that can shift or rotate the supported structure if only one is used. Installing a second tieback in the opposite direction provides a braced, two-point restraint that balances those horizontal forces. This makes the system stable, shares the load, and reduces the risk of anchor movement or failure. A swivel anchor alone wouldn’t address the imbalance; a third tieback in the same direction would compound the unbalanced load; and no additional tieback leaves the setup unstable.
