Where the Boulder price comes from
Labor is 54% of the midpoint bill here, against 52% nationally. The mix of trades behind this job is plumbers, pipefitters and steamfitters (40%), construction laborers (40%), operating engineers and other construction equipment operators (20%). We weight each trade's local median wage by that share and compare it with the national median. In Boulder the blended ratio comes out at 1.05.
Materials are scaled with BEA's regional price parity for goods. Boulder is at 96.1 against 100 for the US, so a materials line of $3,350 nationally becomes $3,250 here (midpoint, 4,000 sq ft of lawn). Permits follow the all-items index of 105.2: $0 to $0.
Who does the work: Boulder trade wages
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 Boulder the blend is 1.05.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $31.20 an hour, in line with the US median of $30.67. The middle half of them earn between $28.30 and $38.49 an hour. About 420 work in the metro. That is 21.8 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 40%) the local median is $23.07 an hour, which is in line with the national $22.66. The middle half of them earn between $19.64 and $28.23 an hour. BLS counts 540 of them working in the area, 28.1 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $34.16 an hour, 19% above the US median of $28.78. The middle half of them earn between $29.51 and $38.37 an hour. About 190 work in the metro. That is 9.9 per 10,000 jobs, compared with 30.7 nationally, so expect fewer 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 $350 to the midpoint estimate; the 25th percentile takes off about $140. That is a swing of roughly 2.0% to 4.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Boulder has 192,390 jobs in total (BLS, May 2025), ranking 119th by size among the 300 metros on this site.
