Insulator (Heat & Frost / Asbestos Worker) prevailing wage, Norfolk County group, Massachusetts (3 counties)
DOL sets the same insulator rates, row for row, in 3 counties: Barnstable, Bristol and Norfolk. Every figure on this page applies in each of them.
$92.08an hour, base wage + fringe benefits (our sum)
$55.45 base wage + $36.63 fringe benefits · ASBE0006-010
On federally funded or assisted building construction in each of these 3 counties, an insulator must be paid at least $92.08 an hour: a $55.45 base wage plus $36.63 in fringe benefits, under wage determination MA20260001 (modification 1). DOL prints no total, so $92.08 is our sum of the two.
Wage determination MA20260001, modification 1, published May 18, 2026, for building construction; rate identifier ASBE0006-010 (September 1, 2024). Checked against sam.gov on October 25, 2026.
Massachusetts also sets its own rates; on jobs covered by both, pay the higher. The Department of Labor Standards issues them per project, by wage request number, and they must be re-requested after 90 days (M.G.L. c. 149 ss. 26-27), so there is no county schedule to show here.
DOL lists 2 insulator rates for each of these counties, from $92.08 to $92.08 an hour. See all of them.
Base wage and fringe benefits: $55.45 + $36.63
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) | $55.45 |
| Fringe benefits (one figure, not itemized) | $36.63 |
| Base + fringe benefits (our sum; DOL prints no total) | $92.08 |
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 Massachusetts change log lists what each one changed.
