Why Davenport prices look the way they do
Labor is 45% of the midpoint bill here, against 42% nationally. The mix of trades behind this job is cement masons and concrete finishers (50%), construction laborers (30%), operating engineers and other construction equipment operators (10%), carpenters (10%). We weight each trade's local median wage by that share and compare it with the national median. In Davenport the blended ratio comes out at 1.09.
Materials are scaled with BEA's regional price parity for goods. Davenport is at 94.2 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 89.1: $45 to $360.
The best months for concrete slab in Davenport
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Davenport (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 Davenport are May through October: 6 of 12. Outside them, January, February, March, April, November and December have an average overnight low of 40°F or below.
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.
Davenport gets about 36 inches of precipitation in a normal year. The wettest months are May, June and July (4.8 inches in May). Inside the workable window, September and October are the driest, at 3.5 and 2.7 inches. The station averages about 13 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.

Who does the work: Davenport 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 Davenport the blend is 1.09.
Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $29.17 an hour, 6% above the US median of $27.41. The middle half of them earn between $23.04 and $33.92 an hour. About 220 work in the metro. That is 12.2 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 30%) the local median is $26.14 an hour, which is 15% above the national $22.66. The middle half of them earn between $21.74 and $33.98 an hour. BLS counts 1,320 of them working in the area, 73.2 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $31.18 an hour, 8% above the US median of $28.78. The middle half of them earn between $25.71 and $40.96 an hour. About 570 work in the metro. That is 31.6 per 10,000 jobs, compared with 30.7 nationally, so the supply of crews looks typical.
Carpenters (47-2031), 10% of the weighting: a median of $29.06 an hour, in line with the US median of $29.12. The middle half of them earn between $23.15 and $35.60 an hour. About 670 work in the metro. That is 37.1 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (cement masons and concrete finishers) from the median to the 75th percentile wage adds about $140 to the midpoint estimate; the 25th percentile takes off about $180. That is a swing of roughly 4.7% to 3.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Davenport-Moline-Rock Island has 180,450 jobs in total (BLS, May 2025), ranking 128th by size among the 300 metros on this site.

Why two Davenport quotes can differ
Finish
A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.
Thickness and mix
A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).
Base and reinforcement
A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.
