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.
