What is behind the Rapid City number
The wage side of the estimate leans on brickmasons and blockmasons, who do 50% of the hours on a typical job. Their local median is $29.03 an hour. Add the other trades involved and the blended wage index for Rapid City is 0.98 (US = 1.00), which puts labor at 47% of the total. BLS does not publish this trade for the metro, so we used the South Dakota statewide median.
Materials are scaled with BEA's regional price parity for goods. Rapid City is at 95.5 against 100 for the US, so a materials line of $5,300 nationally becomes $5,050 here (midpoint, 200 sq ft of wall face). Permits follow the all-items index of 89.2: $45 to $400.
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 Rapid City. The wage table below marks each row.
Why two Rapid City quotes can differ
Permit
Permits cost $50-$450 depending on location and wall size.
Height
Walls over 4 feet need engineering, deeper excavation and more skilled labor; many cities require permits over 3-4 feet (HomeGuide).
Material
Block, poured concrete and natural stone are priced differently; concrete and stone walls run higher than the segmental block default.

Who does the work: Rapid City trade wages
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 Rapid City the blend is 0.98.
Brickmasons and blockmasons (47-2021) carry 50% of the labor weighting. BLS does not publish this trade for the Rapid City metro, so we used the South Dakota statewide median: $29.03 an hour against $29.87 for the US. The middle half of them earn between $22.65 and $31.77 an hour.
For construction laborers (47-2061, weighted 30%) the local median is $21.94 an hour, which is 3% below the national $22.66. The middle half of them earn between $19.14 and $22.91 an hour. BLS counts 410 of them working in the area, 55.5 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $29.16 an hour, in line with the US median of $28.78. The middle half of them earn between $25.29 and $30.59 an hour. About 410 work in the metro. That is 55.5 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (brickmasons and blockmasons) from the median to the 75th percentile wage adds about $220 to the midpoint estimate; the 25th percentile takes off about $500. That is a swing of roughly 5.1% to 2.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Rapid City has 73,820 jobs in total (BLS, May 2025), ranking 249th by size among the 300 metros on this site.
