Who does the work: New Haven trade wages
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 New Haven the blend is 1.12.
Carpenters (47-2031), 80% of the weighting: a median of $31.61 an hour, 9% above the US median of $29.12. The middle half of them earn between $28.64 and $40.18 an hour. About 730 work in the metro. That is 25.9 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 $29.02 an hour, which is 28% above the national $22.66. The middle half of them earn between $23.36 and $35.51 an hour. BLS counts 1,220 of them working in the area, 43.4 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,150 to the midpoint estimate; the 25th percentile takes off about $400. That is a swing of roughly 3.4% to 9.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
New Haven has 281,410 jobs in total (BLS, May 2025), ranking 91st by size among the 300 metros on this site.
