What local crews earn in Kennewick
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 Kennewick the blend is 1.34.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $46.70 an hour, 52% above the US median of $30.67. The middle half of them earn between $29.15 and $61.16 an hour. About 840 work in the metro. That is 64.9 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 40%) the local median is $26.32 an hour, which is 16% above the national $22.66. The middle half of them earn between $21.79 and $33.92 an hour. BLS counts 1,110 of them working in the area, 85.7 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 $38.39 an hour, 33% above the US median of $28.78. The middle half of them earn between $33.53 and $48.81 an hour. About 460 work in the metro. That is 35.5 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 $690 to the midpoint estimate; the 25th percentile takes off about $830. That is a swing of roughly 9.9% to 8.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
