What local crews earn in Norwich
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 Norwich the blend is 0.99.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $22.84 an hour, which is 3% below the national $23.62. The middle half of them earn between $18.49 and $24.34 an hour. BLS counts 60 of them working in the area, 4.7 for every 10,000 jobs (US: 2.9), so the local bench is deeper than average.
For construction laborers (47-2061, weighted 20%) the local median is $24.95 an hour, which is 10% above the national $22.66. The middle half of them earn between $22.01 and $32.96 an hour. BLS counts 390 of them working in the area, 30.8 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $45 to the midpoint estimate; the 25th percentile takes off about $130. That is a swing of roughly 5.4% to 1.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
