How to Use This Template
- 1
Calculate concrete volume in cubic yards: (length × width × thickness in feet) / 27. For a 20×20 ft patio at 4 inches thick, that’s (20 × 20 × 0.333) / 27 = 4.9 cubic yards. Always order 5–10% more than calculated to account for uneven subgrade, spillage, and form irregularities. Running short during a pour is the most expensive mistake in concrete work.
- 2
Specify the concrete mix for the application. Residential flatwork typically uses 3,000–4,000 PSI with a 4–5 inch slump. Footings and structural work may require 4,000+ PSI. List any admixtures: fiber mesh for crack resistance, air entrainment for freeze-thaw climates, accelerator for cold weather, or retarder for large pours in hot weather.
- 3
Itemize reinforcement and formwork separately. Rebar (#3 or #4 on 18–24 inch centers) costs \$0.50–\$1.50 per linear foot. Wire mesh (6×6 W2.9×W2.9) costs \$0.15–\$0.25 per sq ft. Forms using 2×4 or 2×6 lumber cost \$2–\$5 per linear foot. Stakes, form oil, and snap ties for walls are easily forgotten but add up.
- 4
Break finishing into its own section with clear options. Broom finish is standard (no extra cost). Trowel finish adds \$0.50–\$1 per sq ft. Exposed aggregate adds \$2–\$4 per sq ft. Stamped concrete with color adds \$8–\$18 per sq ft. Presenting options lets clients choose their budget level and often leads to upsells on decorative finishes.
Frequently Asked Questions
How do I calculate cubic yards of concrete for an estimate?
Multiply length × width × thickness (all in feet) and divide by 27. For 4-inch thick slabs, use 0.333 ft for thickness. A 10×10 ft slab at 4 inches = (10 × 10 × 0.333) / 27 = 1.23 cubic yards. Always add 5–10% overage. Ready-mix trucks deliver in full yards, so round up. Short loads (under 3–4 yards) usually incur a surcharge of \$30–\$60 per yard.
What PSI concrete should I specify for different projects?
Sidewalks and patios: 3,000 PSI. Driveways: 3,500–4,000 PSI. Garage floors: 3,500–4,000 PSI. Footings and foundations: 3,500–4,000 PSI (check local code). Structural columns and walls: 4,000+ PSI. Always specify PSI on your estimate — it affects the ready-mix price (\$120–\$180 per cubic yard) and shows the client you’re engineering the job correctly.
How do I price concrete work per square foot?
Basic concrete flatwork (4-inch slab, gravel base, broom finish) runs \$6–\$12 per sq ft installed. This includes grading, forms, gravel, concrete, finishing, and curing. Stamped or decorative concrete runs \$12–\$25 per sq ft. Structural work (walls, footings) is priced by the cubic yard or linear foot rather than square footage.
What site prep should I include in a concrete estimate?
Always include excavation (removing topsoil to proper depth), grading for slope/drainage, a 4–6 inch compacted gravel base, and a vapor barrier for slabs adjacent to structures. List each item separately. Excavation runs \$1–\$3 per sq ft, gravel base \$1–\$2 per sq ft. Don’t forget haul-off of excavated material — it’s often \$200–\$500 per truck load.
