Why Bismarck prices look the way they do
We price the labor side from BLS wage data for 3 trades: construction laborers at 50%, operating engineers and other construction equipment operators at 30%, pipelayers at 20%. Weighted together, Bismarck wages are 1.03 times the national level. Labor makes up about 54% of the midpoint estimate (52% at national prices).
Materials are scaled with BEA's regional price parity for goods. Bismarck is at 95.7 against 100 for the US, so a materials line of $650 nationally becomes $620 here (midpoint, 60 linear ft). Permits follow the all-items index of 91.0: $0 to $0.
Data note: 20% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Bismarck. The wage table below marks each row.

What local crews earn in Bismarck
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 Bismarck the blend is 1.03.
For construction laborers (47-2061, weighted 50%) the local median is $23.93 an hour, which is 6% above the national $22.66. The middle half of them earn between $21.87 and $29.41 an hour. BLS counts 620 of them working in the area, 87.0 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 30% of the weighting: a median of $29.88 an hour, 4% above the US median of $28.78. The middle half of them earn between $25.67 and $35.15 an hour. About 580 work in the metro. That is 81.4 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
Pipelayers (47-2151) carry 20% of the labor weighting. BLS does not publish this trade for the Bismarck metro, so we used the North Dakota statewide median: $22.99 an hour against $23.56 for the US. The middle half of them earn between $22.88 and $23.62 an hour.
A quick sensitivity check: moving the lead trade (construction laborers) from the median to the 75th percentile wage adds about $85 to the midpoint estimate; the 25th percentile takes off about $30. That is a swing of roughly 2.4% to 6.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Bismarck has 71,270 jobs in total (BLS, May 2025), ranking 258th by size among the 300 metros on this site.
