How to read a Davis-Bacon wage determination
A wage determination is not a national rate sheet. It is a location- and construction-type-specific schedule that becomes useful only when it is matched to the contract and the work actually performed.
Start at the cover sheet before searching for a trade. The decision number, modification, covered counties, and construction type tell you whether the document belongs to the job in front of you.
Read the cover sheet first
Confirm the state and every county where covered work will occur. Then confirm whether the document covers building, residential, highway, heavy, or more than one construction type. A familiar trade name on the wrong document does not make the rate applicable.
Record the general decision number and modification exactly as shown. For payroll work, compare those identifiers with the wage determination incorporated into the contract—not simply the newest search result available today.
- Decision and modification number
- State, county, or other geographic area
- Construction type
- Publication and superseded-decision information
Read the rate row as a package
Each classification row pairs a basic hourly rate with a fringe-benefit amount. The prevailing wage obligation is the combination of those components, subject to the rules for cash wages and bona fide benefit credits.
Identifiers and footnotes can change how a row should be interpreted. Keep the identifier, effective date, notes, and footnotes with the rate instead of copying only the dollar figures into an estimate.
Treat classification as a work question
The right row follows the work performed and area practice, not a worker’s internal title. If the needed work is not represented, do not borrow a similar-sounding classification. Route a possible missing classification through the contracting officer and conformance process.
