Verify before making a permanent change: hole for takeoff cut too large.
High-risk starter answer - stop before cutting, drilling, coring, sleeving, enlarging, patching, or relocating any opening. An oversized or wrong opening needs a repair plan, not a quick patch nobody approved.
Ask when the cut affects structure, roof, rated wall, damper/access, grease/industrial duct, equipment, or another trade.
Watch out
Do not cut because the duct does not fit.
Check
Confirm the exact location from approved drawings and field marks.
Check what is above, below, behind, or inside the cut.
Verify whether the wall/deck/roof/shaft/beam is structural, rated, waterproofed, post-tensioned, or shared with other trades.
Photograph the opening and ask who owns the repair/detail before covering it.
Steps
Confirm what you are cutting/drilling/fabricating.
Check latest drawing/shop detail.
Look for hidden utilities, structure, rated assemblies, roof membrane, or equipment parts.
Focus on the actual issue: hole for takeoff cut too large.
Photograph or mark the condition if someone else needs to approve it.
