Notes
- Where the number comes from. The national price for a poured concrete slab is $6.50 per ft² of slab — poured slab pricing published for 2026, $4–$11 per ft² for a 4-inch slab on grade. Labor is about 50% of that. Cement Masons and Concrete Finishers near Tri-Cities, WA average $81,900 a year against a U.S. mean of $60,050 — a factor of 1.364 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for cement masons and concrete finishers near Tri-Cities, WA, so this is the Washington state average, SOC 47-2051.
- This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Tri-Cities, WA, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
- Short pour season. 95 freezing days a year in Tri-Cities. ACI 306 cold-weather protection — blankets, heated water, or waiting — is a real line item here, not boilerplate.
- What is in the price: excavation to grade, a compacted gravel base, forms, wire mesh or fibre, the concrete itself, placing, screeding, a broom or trowel finish, and labor.
- What is not: thickened edges for a load-bearing wall, a vapour barrier under a heated slab, rebar mats where an engineer calls for them, saw-cut control joints past the standard spacing, and any grading or drainage work around the pour. These are the lines that turn a $7,683 quote into a $9,603 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

Ask about each of them before you sign. On a job this size they are the difference between $7,683 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $4,728 – $13,001, that is not automatically wrong — but it is the question worth asking out loud.
