Prevailing wage requirements apply to most public construction work and significantly impact labor cost calculations. Understanding these requirements is essential for accurate bidding and legal compliance.
What Is Prevailing Wage
Definition

Wage Determination Interpretation
Understanding the Schedule
- Basic hourly rate

Calculating Labor Costs
Components
What's Included
- Base hourly wage
- Fringe benefits (health, pension, etc.)
- Overtime premiums
- Employer taxes on wages
Fringe Benefits
Options
- Pay as cash to worker
- Provide bona fide benefits
- Combination of both
Bona Fide Benefits
- Health insurance
- Pension contributions
- Vacation pay
- Apprenticeship training
Overtime
Federal Standard
- Time and a half after 40 hours/week
- Some states more restrictive
- Daily overtime in some jurisdictions
- Saturday/Sunday premiums vary
Calculation Overtime rate = Base rate × 1.5 + Fringe benefits (Fringes typically not multiplied)
Example Calculation
Electrician, 45-hour week
Prevailing Wage:
Base: $52.15
Fringe: $28.50
Total: $80.65
Weekly Cost:
Regular (40 hrs): 40 × $80.65 = $3,226.00
Overtime (5 hrs): 5 × ($52.15 × 1.5 + $28.50)
= 5 × $106.73 = $533.65
Weekly Total: $3,759.65

Conclusion
Prevailing wage compliance is non-negotiable on public work. Violations result in back pay, penalties, and potential debarment—consequences that far exceed any savings from non-compliance.
Build accurate prevailing wage costs into your bids. Implement robust payroll and recordkeeping systems. Monitor subcontractor compliance. When in doubt about classifications or rates, err on the side of compliance.
The contractors who succeed on public work treat prevailing wage as a standard business requirement, not an obstacle. Proper systems make compliance manageable and protect your company from costly violations.
