What local crews earn in Decatur
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 Decatur the blend is 0.86.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $28.81 an hour, 6% below the US median of $30.67. The middle half of them earn between $23.04 and $35.82 an hour. About 210 work in the metro. That is 34.3 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 40%) the local median is $18.11 an hour, which is 20% below the national $22.66. The middle half of them earn between $15.52 and $23.05 an hour. BLS counts 690 of them working in the area, 112.7 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), 20% of the weighting: a median of $23.79 an hour, 17% below the US median of $28.78. The middle half of them earn between $21.70 and $28.46 an hour. About 290 work in the metro. That is 47.4 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $330 to the midpoint estimate; the 25th percentile takes off about $270. That is a swing of roughly 4.3% to 5.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Decatur has 61,240 jobs in total (BLS, May 2025), ranking 283rd by size among the 300 metros on this site.

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Decatur Pryor Fld (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Decatur are February through June and September through December: 9 of 12. Outside them, January has an average overnight low at or below freezing (32°F), and July and August have an average daytime high of 90°F or more.
In January the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 62 days a year with a low at or below 32°F at this station.
