The Department of Labor modifies these determinations on SAM.gov in weekly batches through the year; the latest South Carolina modification we hold is dated October 22, 2026. 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).
