Introduction

Concrete is one of the highest cost components in a project. A missing quantity, wrong thickness, or incomplete scope can result in thousands of dollars lost. A proper concrete estimate is not just “cubic yards” — it is a structured breakdown of every element involved in the work.

Here is what a professional concrete takeoff must include.

---

1) Structural & Flatwork Quantities

A complete concrete estimate should break down all structural elements separately:

• Slabs on grade & elevated slabs
• Footings & foundation walls
• Beams, columns & shear walls
• Retaining walls & tilt-up panels
• Sidewalks, curbs & exterior flatwork

Each listed with correct dimensions and waste factors.

2) Reinforcement (Rebar & Mesh)

Concrete without steel is incomplete estimating.
You must include:

• Bar sizes and lengths
• Spacing & lap lengths
• Mesh rolls or sheets
• Couplers, chairs & ties

Rebar alone can change project cost drastically if miscalculated.

3) Formwork, Shoring & Accessories

Most contractors lose money because they ignore formwork.
Proper estimating includes:

• Formwork surface areas
• Shoring/bracing requirements
• Hardware, ties & rentals
• Labor assembly time

Formwork is often more expensive than the concrete itself.

4) Labor, Production & Pour Planning

Concrete cost isn’t only material — labor and production play a key role.

• Crew size and placement rate

• Pour sequence & pump access

• Weather or curing considerations

Ignoring logistics = inaccurate costs.

---

5) Hauling, Waste & Contingencies

Concrete estimating must include realistic allowances for:

• Overbreak or excavation waste
• Delivery & pumping charges
• Site constraints & delays
• Contingency for unknowns

Professional estimates include risk — not just numbers.

Conclusion

A proper concrete estimate is detailed, traceable and justified. When done correctly, it protects your profit, avoids disputes and helps you submit competitive bids with confidence.

Skipping any part of this list is how contractors lose money.
