Why Birmingham prices look the way they do
We price the labor side from BLS wage data for 2 trades: insulation workers, floor, ceiling and wall at 80%, construction laborers at 20%. Weighted together, Birmingham wages are 0.96 times the national level. Labor makes up about 36% of the midpoint estimate (36% at national prices). BLS does not publish this trade for the metro, so we used the Alabama statewide median.
Materials are scaled with BEA's regional price parity for goods. Birmingham is at 96.4 against 100 for the US, so a materials line of $1,600 nationally becomes $1,550 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 91.6: $0 to $0.
Data note: 80% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Birmingham. The wage table below marks each row.
What local crews earn in Birmingham
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 Birmingham the blend is 0.96.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Birmingham metro, so we used the Alabama statewide median: $23.43 an hour against $23.62 for the US. The middle half of them earn between $20.35 and $27.14 an hour.
For construction laborers (47-2061, weighted 20%) the local median is $18.45 an hour, which is 19% below the national $22.66. The middle half of them earn between $15.51 and $22.60 an hour. BLS counts 4,780 of them working in the area, 91.9 for every 10,000 jobs (US: 70.5), so the local bench is deeper 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 $110 to the midpoint estimate; the 25th percentile takes off about $95. That is a swing of roughly 3.9% to 4.7% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Birmingham has 520,290 jobs in total (BLS, May 2025), ranking 50th by size among the 300 metros on this site.
