What local crews earn in Riverside
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 Riverside the blend is 1.17.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $30.73 an hour, in line with the US median of $30.67. The middle half of them earn between $25.57 and $39.06 an hour. About 4,510 work in the metro. That is 26.3 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 $28.61 an hour, which is 26% above the national $22.66. The middle half of them earn between $22.57 and $37.37 an hour. BLS counts 12,120 of them working in the area, 70.6 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $37.85 an hour, 32% above the US median of $28.78. The middle half of them earn between $29.90 and $57.29 an hour. About 4,740 work in the metro. That is 27.6 per 10,000 jobs, compared with 30.7 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $400 to the midpoint estimate; the 25th percentile takes off about $240. That is a swing of roughly 3.2% to 5.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
