Questions about Iowa insulator pay

What is the insulator prevailing wage in Polk County?

$22.18 an hour: a $18.17 base wage plus $4.01 in fringe benefits, under wage determination IA20260071, modification 1. Overtime and every insulator classification in Polk County.

Does insulator prevailing wage include fringe benefits?

Yes. In Polk County the $22.18 total is a $18.17 base wage plus $4.01 in fringe benefits, about 18% of the total. The employer owes the full amount for every hour worked.

Does insulator prevailing wage pay overtime in Iowa?

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 Iowa, the 99 counties with an insulator rate fall into 52 distinct sets of rates, and 8 of those sets are shared by more than one county; the largest covers 19 counties (the Plymouth County group).
