What is behind the Boise number
We price the labor side from BLS wage data for 4 trades: cement masons and concrete finishers at 50%, construction laborers at 30%, operating engineers and other construction equipment operators at 10%, carpenters at 10%. Weighted together, Boise wages are 0.98 times the national level. Labor makes up about 42% of the midpoint estimate (42% at national prices).
Materials are scaled with BEA's regional price parity for goods. Boise is at 96.2 against 100 for the US, so a materials line of $2,000 nationally becomes $1,900 here (midpoint, 400 sq ft). Permits follow the all-items index of 98.4: $50 to $390.
Optional extras in Boise
Add-ons start from national price ranges and are scaled by 0.97 for Boise, which is the average of the area's wage index (0.98) and goods price index (0.96). The estimator above can add them to your total.

Who does the work: Boise trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 4 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Boise the blend is 0.98.
Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $26.95 an hour, in line with the US median of $27.41. The middle half of them earn between $23.13 and $29.50 an hour. About 1,110 work in the metro. That is 28.3 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 30%) the local median is $22.84 an hour, which is in line with the national $22.66. The middle half of them earn between $19.98 and $25.18 an hour. BLS counts 4,700 of them working in the area, 120.0 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $29.29 an hour, in line with the US median of $28.78. The middle half of them earn between $25.58 and $31.56 an hour. About 1,730 work in the metro. That is 44.2 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
Carpenters (47-2031), 10% of the weighting: a median of $24.45 an hour, 16% below the US median of $29.12. The middle half of them earn between $21.63 and $30.30 an hour. About 4,080 work in the metro. That is 104.1 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (cement masons and concrete finishers) from the median to the 75th percentile wage adds about $75 to the midpoint estimate; the 25th percentile takes off about $110. That is a swing of roughly 3.0% to 2.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Boise City has 391,790 jobs in total (BLS, May 2025), ranking 67th by size among the 300 metros on this site.

Concrete slab: what moves the price in Boise
Truck and pump access
If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.
Small-job minimums
Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.
Finish
A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.

The best months for concrete slab in Boise
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Boise Air Terminal (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For pouring concrete, the comfortable months in Boise are May through June and September through October: 4 of 12. Outside them, January, February, March, April, November and December have an average overnight low of 40°F or below, and July and August have an average daytime high of 90°F or more.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Heat matters for concrete as well. With average highs of 90°F or more in July and August, crews often start early, wet the base and plan for faster set times.
Boise gets about 12 inches of precipitation in a normal year, including roughly 18 inches of snow. The wettest months are January, May and December (1.5 inches in December). Inside the workable window, June and September are the driest, at 0.8 and 0.4 inches. The station averages about 55 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
