Questions about Colorado insulator pay

What is the insulator prevailing wage in El Paso County?

$53.80 an hour: a $36.98 base wage plus $16.82 in fringe benefits, under wage determination CO20260022, modification 1. Overtime and every insulator classification in El Paso County.

Does insulator prevailing wage include fringe benefits?

Yes. In El Paso County the $53.80 total is a $36.98 base wage plus $16.82 in fringe benefits, about 31% of the total. The employer owes the full amount for every hour worked.

Does insulator prevailing wage pay overtime in Colorado?

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 Colorado, the 65 counties with an insulator rate fall into 19 distinct sets of rates, and 3 of those sets are shared by more than one county; the largest covers 42 counties (the Garfield County group).
