**About these rates**  
WagePilot mirrors Davis-Bacon general wage determinations from SAM.gov, the official source, and re-checks each one daily. The wage determination incorporated in your contract governs, including its modification number, footnotes and any conformed classifications. WagePilot reviews payroll; it does not file, certify or give legal advice.
