New Jersey's Prevailing Wage Act covers public works construction contracts. Municipal government contracts have a higher threshold that is adjusted periodically. Rates vary by county and trade classification.
New Jersey has an active prevailing wage law (New Jersey Prevailing Wage Act (N.J.S.A. 34:11-56.25 et seq.)). Administered by New Jersey Department of Labor and Workforce Development. Certified payroll is required. Federal Davis-Bacon applies to all federal projects.
If you are bidding public construction in New Jersey, the Prevailing Wage Act (N.J.S.A. 34:11-56.25 et seq.) drives your labor line items, and the trigger threshold depends on who owns the project. For municipal government contracts the threshold sits around $20,125 (it is adjusted periodically), but for every other public entity, utilities, school boards, and authorities, coverage kicks in at just $2,000. That low ceiling means almost any meaningful public job outside of a small town contract is a prevailing-wage job. Price your estimate to the Commissioner of Labor's determinations rather than your shop's standard rates, because New Jersey ties rates to local collective bargaining agreements that vary by county and trade classification.
Build certified payroll into your overhead from day one. The New Jersey Department of Labor and Workforce Development requires weekly certified payrolls, and underpayment exposes you to back wages plus interest, civil penalties, and debarment from public work. Willful violations can carry criminal exposure. Correctly classifying each worker is the single biggest pitfall: paying a laborer rate for work that falls under a higher mechanic classification is the most common audit finding and the fastest way to lose a bid's profit to a back-wage claim.
When a project carries federal money, Davis-Bacon also applies, and you must pay the higher of the two rate schedules trade by trade. Estimators should pull both determinations during the bid phase so the labor burden is right before the number is submitted. Underbidding the labor rate is rarely recoverable through a change order, so confirm county-specific rates, fringe obligations, and overtime rules before you commit a price.
The federal Davis-Bacon Act applies to all federally funded or federally assisted construction contracts over $2,000 in New Jersey. This includes projects funded by federal agencies, FHWA highway projects, HUD housing, and projects receiving federal grants.
Contractors face payment of back wages plus interest, debarment from public contracts, and civil penalties. Criminal penalties may apply for willful violations.
