What is the Davis-Bacon prevailing wage for a ironworker in Missouri?

There is no single figure. Active federal determinations for Missouri publish 72 ironworker classification rates ranging from $20.90 to $44.27 per hour before fringe benefits. The rate that applies depends on the county, the type of construction and the wage determination incorporated into the contract.

How many counties in Missouri have a published ironworker rate?

115 of the counties covered by active federal determinations list at least one ironworker classification.

Do these rates apply to state-funded projects?

No. These are federal Davis-Bacon rates, which apply to federally funded or assisted construction. Missouri may set its own prevailing wage rates for state and locally funded work; the state law summary is on the Missouri prevailing wage page.

This site indexes them and links every determination to its official document - the determination incorporated into a contract governs.

This page collects every classification in Missouri's active federal determinations that is a form of ironworker work (structural steel erection and reinforcing steel) and shows the rate published for it.
