What local crews earn in Blacksburg
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 Blacksburg the blend is 0.91.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Blacksburg metro, so we used the Virginia statewide median: $21.54 an hour against $23.62 for the US. The middle half of them earn between $19.66 and $25.34 an hour.
For construction laborers (47-2061, weighted 20%) the local median is $20.03 an hour, which is 12% below the national $22.66. The middle half of them earn between $17.47 and $22.13 an hour.
A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $120 to the midpoint estimate; the 25th percentile takes off about $55. That is a swing of roughly 2.4% to 4.9% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
