Davis-Bacon Act Compliance: Complete Guide for Construction Contractors 2025

The Davis-Bacon Act affects virtually every federal construction contract. Understanding and maintaining compliance is essential for contractors working on public projects. Non-compliance can result in severe penalties including contract termination, debarment, and criminal prosecution.

What Is the Davis-Bacon Act?

The Davis-Bacon Act of 1931 requires contractors and subcontractors on federal construction contracts exceeding $2,000 to pay workers no less than the locally prevailing wages and fringe benefits.

Key Requirements

| Requirement | Description | |-------------|-------------| | Prevailing wages | Pay at least DOL-determined wage rates | | Fringe benefits | Pay required benefits or cash equivalent | | Certified payroll | Submit weekly certified payroll reports | | Posting | Display wage determinations at job site | | Records | Maintain payroll records for 3 years |

Covered Projects

Davis-Bacon applies to:

  • Federal building construction
  • Federal repair and renovation
  • Federally assisted projects (depending on program)
  • Public works on federal land

Threshold: Contracts exceeding $2,000 in value

Understanding Prevailing Wages

Prevailing wages are determined by the Department of Labor based on local area surveys.

Wage Determination Components

1. Basic Hourly Rate The minimum hourly wage for each classification.

2. Fringe Benefits Required contributions for:

  • Health insurance
  • Pension/retirement
  • Vacation/holiday pay
  • Training funds
  • Other bona fide benefits

3. Total Prevailing Wage Basic rate + fringe benefits = total compensation required

Finding Wage Determinations

Wage determinations are available at:

  • SAM.gov (System for Award Management)
  • Contract documents
  • Contracting officer

Types of Wage Determinations:

  • General (Area) - Most common, by county/locality
  • Project - For specific projects
  • Residential - For residential construction

Reading Wage Determinations

Example wage determination entry:

Classification: Carpenter
Basic Rate: $45.32
Fringe Benefits: $22.15
Total: $67.47

Worker Classification

Proper classification is critical for compliance.

Common Classifications

| Trade | Typical Classifications | |-------|------------------------| | Carpenters | Carpenter, Form Carpenter, Millwright | | Laborers | Common Laborer, Skilled Laborer | | Operating Engineers | Crane Operator, Loader Operator | | Electricians | Journeyman, Apprentice | | Ironworkers | Structural, Reinforcing, Ornamental |

Classification Challenges

Multiple Classifications: Workers performing multiple classifications should be:

  • Paid highest applicable rate for all hours, OR
  • Tracked by hours in each classification and paid accordingly

Helpers vs. Journeymen:

  • Helpers may only perform clearly defined helper duties
  • Cannot replace journeymen for classified work
  • Must be allowed by wage determination

Apprentices:

  • Must be registered in approved program
  • Ratios must comply with program requirements
  • Pay reduced rate per approved schedule

Requesting Additional Classifications

If needed classification not on wage determination:

  1. Submit SF-1444 to contracting officer
  2. DOL reviews and approves/denies
  3. Approved classifications added to project

Certified Payroll Requirements

Certified payrolls are the primary compliance documentation.

Submission Requirements

Frequency: Weekly (within 7 days after pay period)

Required Information:

  • Employee name, address, SSN (last 4)
  • Work classification
  • Hours worked each day
  • Total hours
  • Rate of pay

  • Fringe benefit payment method

Form WH-347

The standard certified payroll form includes:

  • Payroll number and week ending date

  • Employee pay details
  • Compliance certification

Certification Statement: The contractor certifies that:

  • Payroll is correct and complete
  • Classifications are accurate
  • Workers are paid required rates

Fringe Benefit Compliance

Fringe benefits require careful tracking and documentation.

Payment Options

Option 1: Bona Fide Benefit Plans

Bona Fide Benefit Requirements

Benefits must be:

Fringe Benefit Credits

Employer contributions may be credited toward fringe requirements if:
