How much do millwrights earn on prevailing wage jobs in South Carolina?
Every row below is one wage determination line: a millwright classification, in one county, for one construction type, under one funding source. The rate that applies to your project is the row whose county, construction type and funding source all match it — a Highway rate does not apply to a Building project in the same county, and a state determination does not substitute for a federal one.

What is the prevailing wage for a millwright in South Carolina?
Across the 9 federal-funded determination records WageFinder lists for millwrights in South Carolina, total prevailing wage runs from $55.14 to $55.14 per hour, median $55.14. There is no single statewide figure: each county's determination sets its own rate, and the same county can carry different rates for Building, Highway, Heavy and Residential work.
Does the millwright rate include benefits?
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate.

The rest list no separate fringe, meaning the base rate is the whole obligation. Fringe can be paid as bona fide benefit plan contributions, as cash added to the paycheck, or as a mix of both.
