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 Iowa change log lists what each one changed.
