What plumbers, pipefitters and steamfitters and the other trades earn in Illinois
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.47 for Illinois.
For plumbers, pipefitters and steamfitters (47-2152, weighted 40%) the local median is $48.05 an hour, which is 57% above the national $30.67. The middle half of them earn between $34.65 and $57.72 an hour. BLS counts 16,750 of them working in the state, 27.5 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Construction laborers (47-2061), 40% of the weighting: a median of $29.18 an hour, 29% above the US median of $22.66. The middle half of them earn between $22.14 and $45.79 an hour. About 35,940 work in the state. That is 58.9 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
For operating engineers and other construction equipment operators (47-2073, weighted 20%) the local median is $46.99 an hour, which is 63% above the national $28.78. The middle half of them earn between $33.28 and $52.56 an hour. BLS counts 12,290 of them working in the state, 20.2 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.
A crew paid at the 75th percentile for plumbers, pipefitters and steamfitters ($57.72 an hour) would add about $460 to the statewide midpoint; one at the 25th percentile ($34.65) would take off about $640. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 6,098,130 jobs across Illinois (May 2025), which is 3.9% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

Illinois seasons and sprinkler system
Season matters for sprinkler system. For each Illinois metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for digging and ground work.
Chicago has the longest comfortable season of the metros we cover in Illinois at 8 months (April through November); Bloomington has the shortest at 7 (April through October). Rainfall runs from 34 inches a year in Chicago to 40 inches in Springfield.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
