Questions about Indiana insulator pay

What is the insulator prevailing wage in Marion County?

$65.88 an hour: a $40.20 base wage plus $25.68 in fringe benefits, under wage determination IN20260002, modification 2. Overtime and every insulator classification in Marion County.

Does insulator prevailing wage include fringe benefits?

Yes. In Marion County the $65.88 total is a $40.20 base wage plus $25.68 in fringe benefits, about 39% of the total. The employer owes the full amount for every hour worked.

Does insulator prevailing wage pay overtime in Indiana?

Davis-Bacon rates are straight time. On contracts over $100,000, the Contract Work Hours and Safety Standards Act requires 1½ times the basic rate for hours over 40 in a workweek (40 U.S.C. 3702). The fringe is owed for every hour at its straight-time amount.

Do apprentice insulators get this rate?

Davis-Bacon determinations list journeyworker rates. Apprentices in a program registered with DOL or a recognized state agency can be paid the program's percentage of the rate, within its ratio; anyone else gets the full rate (29 CFR 5.5(a)(4)).

Why do some counties have the same insulator rate?

DOL often publishes the same insulator rates for several counties. Across Indiana, the 92 counties with an insulator rate fall into 18 distinct sets of rates, and 16 of those sets are shared by more than one county; the largest covers 19 counties (the Marion County group).
