Which item is NOT listed as a structural anchor point for tiebacks?

• A. Bulkheads
• B. Columns
• C. Water tanks
• D. Skylights

Answer: (D)

Tiebacks need solid, load‑bearing anchors that can transfer lateral forces into a stable structure. Bulkheads, columns, and heavy structures like water tanks are designed to handle these loads and provide reliable anchorage for tiebacks. Skylights, on the other hand, are openings in the roof and are not built to carry or transfer such loads; using one as an anchor would compromise structural integrity and could lead to failure or leaks. For that reason, skylights are not listed as structural anchor points for tiebacks.
