| Section | Qty | Unit |
|---|---|---|
| Concrete | 7.56 | m³ |

Start by matching every line item to drawings, specs, and a measurement rule. For slabs, measure plan area and verify thickness zones. For masonry, measure gross wall area, then deduct openings and movement joints. For finishes, separate floors, walls, and ceilings so coverage assumptions stay realistic. Record units consistently (m³, m², pcs, kg) to avoid conversion drift during pricing.
Waste is not the same as contingency. Waste covers cutting, spillage, laps, damage, and ordering constraints. Typical ranges are 3–8% for concrete placement variation, 5–10% for blocks depending on breakage, 5–12% for tiles due to cuts and pattern, and 5–15% for paint based on surface profile. Keep contingency separate for design changes and site unknowns.
Unit rates should reflect delivered cost, not catalogue prices. For concrete, include pumping, admixtures, or testing if billed per cubic meter. For masonry, blocks may be per piece while mortar is treated as an allowance per square meter. For paint, confirm coverage per liter per coat, then multiply by coats and add waste. For steel, pricing by kilogram works best when bar schedules are incomplete.
A good takeoff becomes a procurement checklist. Compare calculated quantities with supplier pack sizes: tile boxes, paint cans, rebar stock lengths, and block pallets. Round in the direction that reduces site shortages, then note why the rounding occurred. Exporting CSV helps build a rate analysis sheet, while PDF snapshots support approvals, client variations, and audit trails when quantities are revised. Add a revision date and estimator initials to every exported report.
Run quick checks before ordering: confirm dimensions against scale bars, verify deductions are not double-counted, and review extreme outputs that suggest a unit mistake. Compare concrete volume against truck counts, blocks against wall elevation logic, and paint liters against past projects of similar area. When results align with engineering judgement, you can lock quantities and track consumption weekly.
It is a structured list of measured quantities from drawings and specs, mapped to units like m³, m², pcs, and kg. It supports pricing, procurement, and progress tracking by comparing planned quantities to actual consumption.
Use project history, handling conditions, and finish complexity. Start with 5% for general materials, increase for cutting-heavy finishes, and reduce for pre-cut or factory-controlled items. Keep waste separate from contingency for scope changes.
It is a common site approximation derived from steel density and bar diameter in millimeters. Multiply kg/m by total length to estimate weight quickly when detailed bar schedules are not available.
Yes. Subtract doors, windows, and large penetrations from wall or ceiling areas before applying coverage. For small items, it is often faster to keep a standard deduction rule and treat minor differences as waste.
Cross-check with a second method: truck counts for concrete, blocks per course and elevation, tile boxes per room, and paint liters from past projects. Large deviations usually indicate unit errors, missed deductions, or wrong coverage assumptions.
They include the latest calculated items, units, quantities, unit rates, and amounts, plus a total cost line. Use CSV for rate analysis and procurement sheets, and PDF for approvals, sharing, and record keeping.
