Prevailing Wage

In Plain English

Government-mandated minimum wages contractors must pay on public construction projects, set to match local market rates.

Definition

Prevailing wage laws require contractors on public works projects to pay workers at least the wage rates and fringe benefits that prevail in the local area for each trade classification. Federal prevailing wages are set under the Davis-Bacon Act; most states have their own prevailing wage laws. Compliance requires certified payroll reporting and proper worker classification.

Why It Matters in Bidding

Prevailing wage requirements can swing a public-works bid by 20 to 40 percent versus private-sector labor rates, so estimators must apply the correct trade classifications and fringe rates during takeoff or risk a non-compliant, money-losing job. Misclassifying a worker or omitting fringe benefits invites back-pay liability, withheld progress payments, and debarment from future public bidding.

Example

Before bidding a municipal school renovation, an estimator pulls the applicable Davis-Bacon wage determination and loads each trade's base rate plus fringe into the labor portion of the takeoff so the number reflects certified-payroll obligations.

Frequently Asked Questions

It raises labor cost line items because base rates and fringe benefits are mandated minimums, often above your standard pay scale. Estimators must price every trade hour at the published determination rate, then carry the burden into payroll taxes and insurance, which can materially increase the total compared to private work.
Certified payroll is the weekly report documenting each worker's hours, classification, and wages paid, signed under penalty of perjury. Build the administrative cost of preparing it into general conditions. Failure to submit accurate reports can trigger withheld payments, penalties, and damage your ability to win future public awards.
Yes. Every subcontractor and lower-tier sub performing covered work on the project must pay prevailing rates and submit certified payroll. As the prime, you remain responsible for their compliance, so confirm subs have priced prevailing wage into their quotes before relying on those numbers in your bid.
