Preliminary Concrete and Rebar Takeoff Checklist

Before relying on preliminary quantities, verify that your units and geometry are consistent and that the scope matches the estimate.

1. Confirm every length, width, depth, and diameter unit.
2. Check element counts and whether dimensions overlap.
3. Separate geometric volume from procurement allowances.
4. Check whether openings or voids should be deducted.
5. Confirm bar counts, nominal diameters, and straight lengths.
6. Account separately for laps, bends, hooks, cutting loss, and waste.
7. Recalculate representative rows independently.
8. Obtain qualified review for final construction or safety-critical use.
