Concrete Estimating Guide
Concrete work estimating for foundations, driveways, patios, and flatwork projects.
Overview
Concrete estimating is based on cubic yards of material, square footage of formwork, and linear feet of reinforcement. A complete estimate covers excavation, gravel base, formwork, rebar or mesh, concrete delivery, placement and finishing, and curing. Ready-mix concrete prices fluctuate seasonally, and pump truck or boom costs can add significantly when direct pour from the chute is not feasible.
Common Projects
- →Residential driveway (plain or stamped)
- →Patio slab pour
- →Foundation and footings
- →Sidewalks and walkways
- →Retaining walls
- →Garage floor slab
Pricing Factors
- ✓Volume in cubic yards (length x width x depth)
- ✓Concrete mix design and PSI rating
- ✓Finish type (broom, stamped, exposed aggregate, polished)
- ✓Rebar or wire mesh reinforcement requirements
- ✓Pump truck needs based on pour accessibility
- ✓Excavation and gravel base preparation
Materials List
- •Ready-mix concrete (various PSI ratings)
- •Rebar (#3, #4, #5) and tie wire
- •Welded wire mesh (6x6 W1.4)
- •Lumber for formwork (2x4, 2x6, stakes)
- •Gravel or crushed stone base material
- •Expansion joint material and fiber mesh
- •Curing compound or plastic sheeting
- •Form release oil
Estimating Tips
- ★Always order 5-10% more concrete than your calculated volume — short loads are extremely costly in time and quality.
- ★Include pump truck costs ($800-$1,500 minimum) whenever the truck cannot back up to within chute distance of the pour.
- ★Price stamped and decorative concrete at 2-3x the cost of standard broom finish to account for the specialized labor and materials.
- ★Factor in weather contingencies — concrete pours may need to be rescheduled for rain or extreme temperatures.
- ★Include saw-cutting control joints in your estimate at 10-12 foot intervals for slabs.

Common questions about concrete estimating
Multiply length (feet) x width (feet) x thickness (feet), then divide by 27 to convert cubic feet to cubic yards. For example, a 20x20 foot patio at 4 inches thick: 20 x 20 x 0.333 = 133.2 cubic feet / 27 = 4.93 cubic yards. Order 5.5 yards to account for waste.
Fully installed concrete (including base prep, forms, rebar, pour, and finish) typically costs $250-$400 per cubic yard for standard flatwork. Stamped or decorative concrete runs $400-$700 per cubic yard. These prices vary significantly by region and project accessibility.
For a crew of 4 workers, typical production rates are 600-1,000 square feet of flatwork per day for standard broom-finish slabs including forming, pouring, and finishing. Stamped or decorative concrete cuts production in half. Factor in half a day for base prep and forming, and always schedule the pour for morning to allow adequate cure time before nightfall temperatures drop.
