What local crews earn in Columbia
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 Columbia the blend is 0.82.
Carpenters (47-2031), 80% of the weighting: a median of $23.11 an hour, 21% below the US median of $29.12. The middle half of them earn between $20.13 and $28.49 an hour. About 880 work in the metro. That is 22.3 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $20.49 an hour, which is 10% below the national $22.66. The middle half of them earn between $17.50 and $23.15 an hour. BLS counts 2,610 of them working in the area, 66.2 for every 10,000 jobs (US: 70.5), so the local bench is about average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $730 to the midpoint estimate; the 25th percentile takes off about $410. That is a swing of roughly 4.0% to 7.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Columbia has 394,200 jobs in total (BLS, May 2025), ranking 65th by size among the 300 metros on this site.
