Davis-Bacon is the only prevailing wage here (federally funded or assisted work). Idaho repealed its law in 1985 (DOL state table).

This base is below $13.65, the Executive Order 13658 minimum. Contracts that order covers must pay at least that (see the WD's note).

Base wage and fringe benefits: $11.25 + $0.00

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.

When does this rate change?

A contract keeps the wage determination in its bid documents. Modifications published before bid opening apply to it, though one published less than 10 days before can be left out if the agency finds there isn't time to tell bidders (29 CFR 1.6(c)).
DOL changes a WD by publishing a numbered modification on SAM.gov. This page reads the modification named in the Source line; the Idaho change log lists what each one changed.
