What is behind the Lafayette number
The wage side of the estimate leans on glaziers, who do 50% of the hours on a typical job. Their local median is $22.67 an hour. Add the other trades involved and the blended wage index for Lafayette is 0.81 (US = 1.00), which puts labor at 25% of the total. BLS does not publish this trade for the metro, so we used the Louisiana statewide median.
Materials are scaled with BEA's regional price parity for goods. Lafayette is at 93.7 against 100 for the US, so a materials line of $7,100 nationally becomes $6,650 here (midpoint, 10 windows). Permits follow the all-items index of 87.2: $0 to $0.
Data note: 50% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Lafayette. The wage table below marks each row.

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Lafayette Rgnl Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.

What local crews earn in Lafayette
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 Lafayette the blend is 0.81.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Lafayette metro, so we used the Louisiana statewide median: $22.67 an hour against $27.44 for the US. The middle half of them earn between $18.73 and $28.47 an hour.
Carpenters (47-2031), 40% of the weighting: a median of $22.81 an hour, 22% below the US median of $29.12. The middle half of them earn between $18.55 and $27.69 an hour. About 580 work in the metro. That is 32.3 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For general maintenance and repair workers (49-9071, weighted 10%) the local median is $19.68 an hour, which is 17% below the national $23.84. The middle half of them earn between $16.12 and $23.30 an hour. BLS counts 2,100 of them working in the area, 116.9 for every 10,000 jobs (US: 98.4), so the local bench is deeper than average.
A quick sensitivity check: moving the lead trade (glaziers) from the median to the 75th percentile wage adds about $280 to the midpoint estimate; the 25th percentile takes off about $190. That is a swing of roughly 2.2% to 3.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Lafayette has 179,570 jobs in total (BLS, May 2025), ranking 129th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

| Glaziers (47-2121) | 50% | $18.73 | $22.67 | $28.47 | $27.44 | 0.83 | state |
