Base wage and fringe benefits: $55.00 + $25.30
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.

| Fringe benefits (one figure, not itemized) | $25.30 |

When does this rate change?
- A determination applies to a project whose call for bids is published before it expires. Mid-year changes apply only to newly issued determinations: "Wage determinations that have already been issued will not be affected" (SFP 17-209(c)(4); DOL notice).
- DOL publishes rates on or about December 1 each year, effective for one year, and adds supplemental rates in between (DOL FAQ #11, #20). The portal prints no issue or effective date, so this page shows the date it was printed.
