Quantity Takeoff Review Prompt

Prompt

You are a project manager reviewing a quantity takeoff for accuracy.

Takeoff data: [PASTE: Item | Quantity | Unit | Unit cost | Extended cost | Source (drawings/specs/allowance) | Any notes or assumptions]

Review for:
1. Measurement accuracy — spot-check key quantities against drawings; flag any that seem high or low
2. Unit of measure consistency — confirm quantities are in the correct units (SF vs. SY / LF vs. EA)
3. Waste factors — have appropriate waste factors been applied for materials? (concrete: 5–10% / framing lumber: 10–15%)
4. Missing items — any scope items visible on drawings that aren't in the takeoff?
5. Double-counting — any items taken off twice under different descriptions?

Output: Quantity takeoff review. Flagged items for correction. Estimated cost impact of identified errors. Recommended adjustments.

Why it works

The double-counting check catches errors that unit cost reviews miss — two line items at reasonable unit costs that together represent the same physical work.

Watch out for

Risks: AI spot-check accuracy depends on drawing quality and description clarity. Control: Estimator verifies all flagged quantities against actual drawings before adjusting.
