South Carolina's Public Works Regulations

Unlike some states, South Carolina does not have a specific prevailing wage law. However, public works projects in the state are subject to federal regulations if federal funding is involved.

Federal Law: The Davis-Bacon and Related Acts apply to federally funded or federally assisted construction projects in South Carolina, including federal-aid highway construction administered by the South Carolina Department of Transportation.
State Law: There is no "Little Davis-Bacon Act" or state-specific prevailing wage law in South Carolina.

The Davis-Bacon Act applies to public works projects when federal contract value reaches $2,000. Contractors and subcontractors on covered projects must adhere to the prevailing wage rates for the job classifications in the local area where the project is performed, including funds passed through state agencies or local public entities.

Definition of "Public Works" in South Carolina

In South Carolina, "public works" refers to the construction, repair, or maintenance of public infrastructure or government-owned facilities funded wholly or partly by public funds. Public works can include:

  • Roads, highways, and bridges, often delivered through SCDOT
  • Government buildings, schools, and libraries
  • Water and sewage systems
  • Parks and recreational facilities
  • Federally assisted energy projects, including solar, wind, broadband, and EV charging stations

Public works projects in South Carolina are subject to prevailing wage requirements only when federal funding triggers Davis-Bacon coverage at the $2,000 threshold.

Prevailing Wage Determinations: Federal (Davis-Bacon) Requirements

Since South Carolina has no state-specific prevailing wage laws, the U.S. Department of Labor sets prevailing wages for federally funded projects under the Davis-Bacon Act. Key points include:

  • Wage rates are based on surveys of wages paid to similar workers in the local area and include both a basic hourly wage and fringe benefits.
  • Different rates apply for various worker classifications such as laborers, carpenters, and electricians.
  • Wage determinations are published on SAM.gov by county and construction type, and contractors apply the determination in effect ten days before bid opening.

Components of Wage Determinations

Federal wage determinations for South Carolina consist of:

  • Basic Hourly Rate: The minimum hourly wage paid to workers in a specific job classification, excluding fringe benefits. South Carolina counties carry different rates because Davis-Bacon surveys are county-specific.
  • Fringe Benefits: Health insurance, retirement, paid leave, or other benefits paid on top of the basic rate.
  • Total Hourly Rate: The sum of the basic hourly rate and fringe benefits. For example, if the basic rate is $20 and fringe is $5, the total hourly rate is $25. Workers must receive the full $25 in cash wages if the contractor does not provide fringe benefits, or a combination of basic wage and bona fide benefits totaling $25 per hour worked.

  • Back Wages owed to underpaid workers, with prime contractors liable for unpaid wages owed by their subcontractors

  • Criminal Exposure for willful falsification of certified payroll under federal false statement statutes
  • Debarment for up to three years from future federally funded contracts

  • Withholding of Contract Payments by the contracting agency, including cross-withholding from any other federal contract held by the same contractor

  • Liquidated Damages of per worker per day for overtime violations under the Contract Work Hours and Safety Standards Act 

Unique Aspects of South Carolina's Public Works System

Unique Aspects of South Carolina's Public Works System

  • Federal-Only Coverage: South Carolina relies solely on federal Davis-Bacon for prevailing wage requirements. State and locally funded projects carry no separate wage floor.
  • SCDOT Federal-Aid Administration: SCDOT incorporates Davis-Bacon obligations into its 2025 Standard Specifications for Highway Construction and requires federal-aid contractors to file annual Form FHWA-1391 workforce composition reports each July.
  • HUD CDBG Program: Davis-Bacon coverage extends to HUD Community Development Block Grant projects administered through the South Carolina Department of Commerce, which often fund local infrastructure and housing work.
  • Environmental Overlays: Public works projects in ecologically sensitive areas of South Carolina, including the Lowcountry, may carry environmental review requirements that affect project timelines and contracting.
