What local crews earn in Pittsburgh
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 Pittsburgh the blend is 1.03.
Carpenters (47-2031), 50% of the weighting: a median of $29.41 an hour, in line with the US median of $29.12. The middle half of them earn between $23.40 and $38.14 an hour. About 5,920 work in the metro. That is 53.1 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $30.44 an hour, 11% above the US median of $27.41. The middle half of them earn between $28.32 and $30.95 an hour. About 1,500 work in the metro. That is 13.5 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $33.34 an hour, which is 10% above the national $30.38. The middle half of them earn between $27.39 and $47.62 an hour. BLS counts 5,210 of them working in the area, 46.7 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $33.70 an hour, 10% above the US median of $30.67. The middle half of them earn between $28.74 and $40.80 an hour. About 2,910 work in the metro. That is 26.1 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $29.14 an hour, which is in line with the national $28.33. The middle half of them earn between $23.33 and $35.13 an hour. BLS counts 380 of them working in the area, 3.4 for every 10,000 jobs (US: 5.3), so the local bench is thinner than average.
Roofers (47-2181), 10% of the weighting: a median of $25.17 an hour, 6% below the US median of $26.65. The middle half of them earn between $22.82 and $29.62 an hour. About 770 work in the metro. That is 6.9 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $5,750 to the midpoint estimate; the 25th percentile takes off about $3,950. That is a swing of roughly 6.7% to 9.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Pittsburgh has 1,114,490 jobs in total (BLS, May 2025), ranking 29th by size among the 300 metros on this site.
