Who does the work: Sioux Falls trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 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 Sioux Falls the blend is 0.85.
Carpenters (47-2031), 80% of the weighting: a median of $23.75 an hour, 18% below the US median of $29.12. The middle half of them earn between $22.22 and $29.38 an hour. About 1,640 work in the metro. That is 91.8 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $22.53 an hour, which is in line with the national $22.66. The middle half of them earn between $18.79 and $23.83 an hour. BLS counts 700 of them working in the area, 39.2 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,650 to the midpoint estimate; the 25th percentile takes off about $450. That is a swing of roughly 2.8% to 10.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Sioux Falls has 178,590 jobs in total (BLS, May 2025), ranking 130th by size among the 300 metros on this site.
