Data Sources
DOL Wage and Hour Division
The primary source for all Davis-Bacon and SCA wage determinations. The Wage and Hour Division publishes active WDs and historical revisions through the Wage Determinations OnLine (WDOL) system.
SAM.gov Wage Determinations
Active Davis-Bacon and Service Contract Act wage determinations are retrieved from the public SAM.gov wage-determination service that powers the SAM.gov website. Each determination's full document — trade classifications, base rates, and fringe amounts — is parsed and stored for fast county- and trade-level lookup.
Geographic Coverage
County and state pages are built directly from the locations named in the wage determinations themselves, covering all 50 states plus the District of Columbia and U.S. territories (Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands).
Derived from DOL wage-determination coverage areas.
Data Currency
Wage determinations are updated when DOL publishes new revisions, typically annually. Always verify the current revision with the DOL WDOL system or your contracting agency before relying on rates for payroll or bidding purposes.
