Prevailing Wage Rate (Federal)

A prevailing wage rate (in the federal contracting context) is the minimum hourly compensation, including a base wage rate and a cash equivalent of fringe benefits, that contractors must pay covered workers on federal contracts subject to the Davis-Bacon Act or Service Contract Labor Standards, set by the Department of Labor to reflect what workers in that classification typically earn in the local labor market.

What is a Prevailing Wage Rate?

The prevailing wage rate concept is anchored in the principle that federal government contracting should not undermine local wage standards by creating demand for below-market labor. Rather than allowing contractors to pay whatever rate the labor market clears at in a competitive sense, the law establishes a floor: the prevailing rate for the type of work in the community where the work is performed.

For Davis-Bacon construction work, the prevailing wage is determined by DOL wage surveys of construction workers in each county or metropolitan area, broken down by craft (carpenter, electrician, plumber, ironworker, laborer) and construction type (residential, building, highway, heavy). The prevailing rate for a classification is set at the rate paid to a majority of workers in that classification, per the 2023 rule update, or the weighted average rate if no single rate is paid to a majority.

For SCLS service work, the prevailing rate reflects survey data and collective bargaining agreement rates for service occupations in the locality. The 2023 SCLS regulations indexed many SCLS occupational rates to the Federal minimum wage as a floor, ensuring WD rates are always at least equal to the applicable federal minimum.

The prevailing wage rate is expressed as two components: a basic hourly rate (cash wages) and a fringe benefit rate (cash equivalent of benefits including health insurance, retirement, vacation, and other non-cash compensation). The total of these two components represents the contractor's minimum total compensation obligation per covered worker-hour. Contractors who provide genuine fringe benefits (health insurance, retirement plans, paid leave) can count the value of those benefits toward the fringe component, reducing the cash wage obligation needed to reach the required total.

Why Prevailing Wage Rates Matter for Government Contractors

Prevailing wage compliance is a binary pass/fail proposition with serious consequences for failure. Contractors cannot negotiate below prevailing wage rates, cannot use geographic differentials within the same county to pay less in suburban locations, and cannot offset one classification's shortfall with a surplus in another. Building accurate prevailing wage costs into proposals, using the actual WD rates for the specific work location and labor classifications, not general market survey data, is the only compliant approach to pricing covered federal contracts.

Example

A facilities services contractor proposes a $5.2M housekeeping services contract for a federal medical center in Pittsburgh, PA. The applicable SCLS WD lists Janitors/Cleaners at a basic rate of $18.73/hr with fringe of $5.05/hr (total obligation: $23.78/hr). The contractor's commercial Pittsburgh housekeeping rate is $16.50/hr base with $2.80/hr benefits (total: $19.30/hr), $4.48/hr below the WD requirement. For 60 covered workers averaging 1,920 hours per year, the WD compliance premium is $4.48/hr × 60 workers × 1,920 hours = $515,712 annually in additional labor cost above commercial market rates. This premium must be priced into the proposal, it is not optional.

Frequently Asked Questions

Can a contractor use a "bona fide fringe benefit plan" to reduce the cash wage it pays?

Yes. FAR 52.222-26 and 29 CFR Part 4 allow contractors to count the actual cost of "bona fide" fringe benefits (health insurance, retirement contributions, vacation accrual, holidays, and other qualifying benefits) toward the WD fringe benefit requirement. If the contractor's benefit package costs $6.50/hr per covered employee and the WD fringe requirement is $5.05/hr, the contractor has met the fringe obligation with its existing benefits and need not pay any cash fringe. If the benefit package costs only $3.25/hr, the contractor must pay the $1.80/hr shortfall in cash wages to reach the required $5.05/hr total fringe obligation.

What is "annualization" of vacation and holiday benefits under SCLS?

DOL requires that the cost of paid vacation and holidays be annualized when determining whether a benefit plan meets the WD fringe requirement. If a contractor provides 10 days of vacation and 10 federal holidays, the total value (20 days × daily wage rate / 52 weeks) is included in the benefit package calculation. Contractors sometimes undercount vacation and holiday benefits by valuing them at cost (the actual days accrued) rather than their DOL-required annualized value. Proper annualization typically increases the calculated value of PTO benefits.

Does the prevailing wage rate apply to overtime hours?

The prevailing wage rate is the minimum straight-time hourly rate. Overtime (hours above 40 per week) must be paid at the Fair Labor Standards Act rate of 1.5 times the regular rate, where the "regular rate" includes all wages and may be higher than the WD minimum if the contractor pays above the WD rate. Contractors with covered employees who regularly work overtime must account for the premium overtime cost in their proposals, factoring both the WD minimum and the FLSA overtime premium requirement.

Are prevailing wage rates the same as minimum wage requirements?

No. Federal, state, and local minimum wage laws establish the lowest wage that may be legally paid to any worker. Prevailing wage rates are a separate and typically higher requirement for covered workers on specific federal contracts. In most cases, the Davis-Bacon or SCLS prevailing wage rate in a given market will exceed the applicable minimum wage significantly, prevailing wages reflect skilled and semi-skilled craft work, not entry-level employment. Contractors must comply with both: pay no less than the minimum wage required by law and no less than the prevailing wage rate for covered work.
