Insulator (Heat & Frost / Asbestos Worker) prevailing wage, Richland County group, North Dakota (6 counties)
DOL sets the same insulator rates, row for row, in 6 counties: Dickey, Emmons, Grant, Ransom, Richland and Sargent. Every figure on this page applies in each of them.
$18.85an hour, base wage + fringe benefits (our sum)
$16.68 base wage + $2.17 fringe benefits · SUND2012-025
On federally funded or assisted building construction in each of these 6 counties, an insulator must be paid at least $18.85 an hour: a $16.68 base wage plus $2.17 in fringe benefits, under wage determination ND20260036 (modification 2). DOL prints no total, so $18.85 is our sum of the two.
Wage determination ND20260036, modification 2, published May 18, 2026, for building construction; rate identifier SUND2012-025 (August 18, 2014). Checked against sam.gov on October 25, 2026.
Davis-Bacon is the only prevailing wage here (federally funded or assisted work). North Dakota has no state prevailing wage law (DOL state table).
Base wage and fringe benefits: $16.68 + $2.17
The base wage is the taxable hourly wage. DOL prints the fringe benefits as one hourly figure, not itemized; it can go to health, pension, vacation and training plans, or be paid as cash where the state allows.
| Base wage (taxable) | $16.68 |
| Fringe benefits (one figure, not itemized) | $2.17 |
| Base + fringe benefits (our sum; DOL prints no total) | $18.85 |
When does this rate change?
- A contract keeps the wage determination in its bid documents. Modifications published before bid opening apply to it, though one published less than 10 days before can be left out if the agency finds there isn't time to tell bidders (29 CFR 1.6(c)).
- DOL changes a WD by publishing a numbered modification on SAM.gov. This page reads the modification named in the Source line; the North Dakota change log lists what each one changed.
