Under the DBRA legislation, you must pay no less than the prevailing wages and benefit rates that are listed on the Davis-Bacon wage decision.  It should be for the lowest specialized trader that is most similar to your trade.  For example, if you are a plumbing contractor and cannot find it listed on the wage decision, you will need to find a different specialized trade (like carpentry) and cannot pay less than the prevailing wage for that trade.  When you receive the special determination, you must correct your payroll if you paid lower than what was decided upon.
