Key Findings
- Unit price is only one line. Delivery, short-load minimums, fuel, environmental fees, standby time, and pump or buggy charges can become the deciding cost.
- Under-ordering is not a bargain when it causes a second delivery, cold joint, emergency bagged fill, or crew downtime.
- Mix requirements should be quoted explicitly. Strength, air entrainment, slump, aggregate size, fibers, accelerators, retarders, and color can all change the order.
The Price Problem
Homeowners often ask for the cost of concrete as though the answer were a commodity price. A ready-mix quote is more specific than that. The supplier prices a load with a plant location, delivery window, truck schedule, order size, requested mix, site access, and local fee structure. A six-yard driveway pour near the plant and a two-yard patio pour across town can have a similar yard price and a very different delivered total.
The most common surprise is the short-load fee. Ready-mix trucks have capacity, fuel, washout, driver time, dispatch time, and opportunity cost whether the order fills the drum or not. Orders below a supplier minimum often carry a fee that makes the effective cost per yard higher. That does not mean small orders are wrong. It means buyers should compare the finished delivered total, not the base yard price alone.
Cost Drivers to Separate Before Comparing Quotes
| Line item | Why it changes | Buyer check |
|---|---|---|
| Base yard price | Plant market, cementitious content, aggregate, strength class, admixtures, and seasonal demand. | Ask what mix assumptions are included, not only dollars per yard. |
| Short-load fee | Order size falls below the supplier's minimum efficient delivery quantity. | Compare the fee against adding useful yardage or combining pours. |
| Access or placement fee | Truck cannot reach the forms, needs a pump, needs buggy travel, or risks site delay. | Measure chute reach, path width, overhead clearance, slope, and washout location. |
| Standby or waiting time | Forms, crew, inspection, pump, or site traffic are not ready when the truck arrives. | Confirm the included unload window and per-minute or per-hour charge. |
| Tax and local fees | Jurisdiction and invoice structure determine whether tax applies to material only or other lines. | Ask whether the quote is before tax, after tax, or partially taxed. |
Waste Is a Cost Control, Not a Guessing Game
Waste allowance is often framed as extra concrete, but it is really a risk allowance for measurement error, uneven excavation, forms that move, overbreak, surface irregularities, and small placement losses. A disciplined five to ten percent allowance may prevent a far more expensive second delivery. Excessive waste is also a problem: too much leftover concrete creates disposal, washout, and site cleanup issues.
The useful number is not "as little as possible." It is the smallest order that still protects the pour from realistic field variation. Footings with rough trench walls, thickened edges, steps, piers, and hand-shaped forms deserve more review than a simple rectangle. Slabs with multiple thicknesses should not be collapsed into one average depth unless the measurement method is clear.
Method Note
This report treats ready-mix pricing as a buyer comparison problem rather than a national price survey. It uses common invoice categories, delivery assumptions, and concrete-ordering practices described in producer education, contractor estimating guides, and ACI/PCA concrete construction references. Prices are intentionally not published because they vary by market and date.
Questions to Ask Before Ordering
- What cubic-yard quantity is being quoted after waste, and what is the minimum-load threshold?
- Is the quoted mix air-entrained, fiber-reinforced, accelerated, retarded, or otherwise modified?
- How long is included for unloading before standby fees begin?
- Can the truck chute reach the forms, or does the site need a pump, buggy, or wheelbarrow plan?
- Which quote lines are taxable, and is the total shown before or after tax?
- What happens if the site is not ready because inspection, forming, reinforcement, or pump setup is late?
Practical Implication
A clean quote comparison starts with the same quantity, same mix, same delivery window, same access assumption, and same tax treatment. If those lines are not aligned, the lowest yard price may not be the lowest delivered cost.
