On federal and federally assisted projects, the Davis-Bacon Act applies this to construction contracts above $2,000, with rates published as wage determinations and certified payrolls submitted weekly to prove compliance. Many states — California among them — have their own prevailing-wage laws (“Little Davis-Bacon” statutes) that apply to state-funded work, sometimes with stricter rules.
A wage determination lists a required base hourly rate plus a fringe benefit amount for each labor classification, and the fringe can be paid as bona fide benefits or added to the cash wage. Workers must be classified by the work they actually perform, and time split across classifications has to be tracked — apprentices count only within registered programs and approved ratios, a common audit pitfall. Misclassifying workers or underpaying fringes can mean back wages, penalties, and even debarment. Because the applicable wage determination is part of the bid documents, Nonlinear surfaces the prevailing-wage requirement during Spec Takeoff and can support the payroll and compliance reporting that keeps a project audit-ready.
