Insulator (Heat & Frost / Asbestos Worker) prevailing wage, Davison County group, South Dakota (10 counties)
DOL sets the same insulator rates, row for row, in 10 counties: Bon Homme, Clay, Davison, Douglas, Hanson, Hutchinson, Lake, Miner, Moody and Sanborn. Every figure on this page applies in each of them.
$89.37an hour, base wage + fringe benefits (our sum)
$55.34 base wage + $34.03 fringe benefits · ASBE0034-007
On federally funded or assisted building construction in each of these 10 counties, an insulator must be paid at least $89.37 an hour: a $55.34 base wage plus $34.03 in fringe benefits, under wage determination SD20260023 (modification 2). DOL prints no total, so $89.37 is our sum of the two.
Wage determination SD20260023, modification 2, published May 18, 2026, for building construction; rate identifier ASBE0034-007 (June 9, 2025). Checked against sam.gov on October 25, 2026.
Davis-Bacon is the only prevailing wage here (federally funded or assisted work). South Dakota has no state prevailing wage law (DOL state table).
Base wage and fringe benefits: $55.34 + $34.03
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) | $55.34 |
| Fringe benefits (one figure, not itemized) | $34.03 |
| Base + fringe benefits (our sum; DOL prints no total) | $89.37 |
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 South Dakota change log lists what each one changed.
