Federal Davis-Bacon is not the only rule that applies here. Applies to public works projects valued over $75,000, built by or on behalf of state and local public bodies. That runs on top of, not instead of, the federal WH-347 whenever the project also has federal money in it.

What this means for your paperwork
Whenever a Missouri project has federal money in it, the WH-347 side of it still has to happen on top of the state paperwork. Certified Payroll only handles the federal side: it checks the rate against the live SAM.gov wage determination and fills out the WH-347 with its Statement of Compliance. It does not file Missouri's own state form, so budget for that as a separate step if this project needs it.
Frequently asked
Does Missouri have its own prevailing wage law?+
Yes. Missouri Revised Statutes §§ 290.210-290.340 set the state's own prevailing wage requirement.
Does Certified Payroll file Missouri's state certified payroll form?+
No. Certified Payroll files the federal WH-347 under Davis-Bacon, not Missouri's own state form. The moment a Missouri project is also federally funded, it checks the rate and fills out the WH-347 automatically. The state form is still a separate filing.
