Concrete Volume Spreadsheet
Civil Geo Tools

Purpose
Use this worksheet to turn field dimensions into order quantities with waste, unit conversion, and a clear record of what was included. It is written for quick checks on slabs, pads, grade beams, continuous footings, and simple rectangular placements.

Inputs To Record
[ ] Plan dimensions, thickness, thickened edges, steps, and turndowns
[ ] Openings, blockouts, construction joints, and deducted areas
[ ] Specified units, density if weight is needed, and assumed waste percentage
[ ] Concrete strength, exposure class, slump, air, and delivery constraints where known

Calculation Checks
[ ] Convert every dimension to one unit system before multiplying
[ ] Calculate base volume, added volume, deductions, and waste separately
[ ] Round order quantity practically, but keep the calculation record unrounded
[ ] Compare against drawings, field measurements, and supplier minimum order requirements

Engineering notes
- Concrete takeoff is not a structural design check.
- For irregular geometry, break the placement into simple shapes and keep a sketch with the worksheet.
- Do not hide waste factor inside the dimensions; show it as a separate line item.
