One rate, fringe benefits included: $76.68
DLS publishes a single hourly figure that already includes fringe benefits. A contractor can pay it all as wages, or pay part as contributions to bona fide benefit plans for the worker, as long as the two add up to at least $76.68. DLS doesn't publish a base and fringe split, so this page doesn't invent one.
When does this rate change?
- The rates attached to the call for bids "shall remain in effect for the duration of that particular contract" (RSMo 290.250). Where a rate comes from a union agreement, DLS may issue replacement pages for its yearly raise.
- DLS files the initial Annual Wage Order by March 10; objections are due in 30 days and the final order by July 1 (RSMo 290.262). AWO 33 was filed March 10, 2026 and became final May 29, 2026.

Davis-Bacon operating engineer rate in St. Clair County
Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. When a contract requires both the state rate and the Davis-Bacon rate, paying the higher of the two meets both. The contract documents say which apply.
We don't put a federal figure next to DLS's here, because the federal determinations split this trade into groups that don't line up with DLS's. The federal rows for this trade are below; match the classification to the work.
