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)). Checked against sam.gov on October 25, 2026.
Davis-Bacon is the only prevailing wage here (federally funded or assisted work). South Carolina has no state prevailing wage law (DOL state table).
