Not marking anchor points before drilling overhead

Mark anchor points clearly before drilling overhead, then verify the marks against the approved detail.

Stop if

• Can you verify these anchor marks before I drill overhead?

Watch out

• Do not drill overhead anchors from memory or vague marks.

Check

• Confirm hanger line/control point.
• Mark all anchor locations.
• Check spacing/detail before drilling.
• Look for no-drill zones/embedded utilities.
• Ask before drilling if any mark is questionable.
