Prevailing Wage Requirements in Pennsylvania: Government Contract Rules

The Davis-Bacon Act, 40 U.S.C. § 3141 et seq., requires prevailing wage payments on all federal construction projects and federally-assisted construction projects exceeding $2,000. The U.S. Department of Labor (DOL) establishes prevailing wage rates for each county and trade classification, published in the Federal Register and maintained in the Wage Determination database.

Under Davis-Bacon, contractors and subcontractors must pay workers no less than the prevailing wage rate, which includes base hourly wages plus fringe benefits such as health insurance, pension contributions, and vacation pay. The law covers laborers, mechanics, and workers in apprenticeable trades. Employers are required to submit weekly payroll certifications and maintain detailed records of wages paid.

Enforcement occurs through the DOL Wage and Hour Division. Violations can result in withholding of contract payments, civil penalties, debarment from future federal contracts, and back wage liability. Workers may file complaints with the DOL, and the agency conducts audits and investigations. Class action lawsuits are also available to workers for wage theft.

The Pennsylvania Prevailing Wage Act, 43 P.S. § 165-1 et seq., establishes a separate state-level prevailing wage requirement that mirrors but does not exceed the federal Davis-Bacon framework. Pennsylvania law applies to all public works construction projects, including projects funded by the Commonwealth, municipalities, school districts, and other public entities, when the project cost exceeds $25,000. This threshold is higher than the federal $2,000 Davis-Bacon threshold, meaning some smaller federal projects trigger Davis-Bacon but not Pennsylvania state law.

The Pennsylvania Department of Labor & Industry establishes and maintains prevailing wage rates for each county in the state. These rates are typically aligned with or derived from union scale wages and include base wages plus fringe benefits. Prevailing wage rates in Pennsylvania vary substantially by county and trade—rates in urban counties like Philadelphia and Allegheny are generally higher than in rural counties.

Pennsylvania law covers contractors, subcontractors, and workers on public works projects. The definition of "public works" includes construction, reconstruction, alteration, maintenance, or repair of publicly-owned buildings, roads, bridges, and infrastructure. Unlike federal Davis-Bacon, Pennsylvania law does not extend to all federally-funded projects; it applies only to projects where Pennsylvania public funds are involved or where the state exercises regulatory authority.

Key differences: Pennsylvania's $25,000 threshold means smaller projects may not trigger state prevailing wage requirements, though federal projects must still comply with Davis-Bacon. Pennsylvania rates are county-specific and updated by the state labor department, not the federal government. Pennsylvania law includes strong debarment provisions—contractors who violate prevailing wage are barred from public contracts for extended periods.

Remedies under Pennsylvania law include wage restitution, civil penalties of up to 10% of the contract price, debarment from future public contracts, and attorney's fees for workers or worker representatives. The state labor department investigates complaints and audits contractor payroll records.

Prevailing wage does not apply to private construction projects, even if large or high-value. If a project is entirely privately funded with no public entity involvement, prevailing wage requirements do not trigger, even if the work is substantial. Projects costing under $25,000 are exempt under Pennsylvania state law, though federal Davis-Bacon still applies if federal funds are involved.

Employers are not required to pay prevailing wage to certain categories of workers: apprentices enrolled in registered apprenticeship programs may be paid at a reduced apprentice rate (typically 50% of prevailing wage, increasing by 10% each half-year); trainees and interns in structured programs may be exempt; workers in supervisory or administrative roles not directly performing labor may not be covered, though the definition of "covered worker" is broad and disputed in litigation.

Common employer defenses include: the project does not meet the cost threshold or public entity requirement; the worker is not engaged in "public works" as defined (e.g., they are security personnel rather than construction workers); the worker is an independent contractor not subject to prevailing wage; or the worker was paid at least the prevailing rate even if records are incomplete. However, misclassification as independent contractor is not a successful defense if the worker is economically dependent on the contractor.

Union agreements do not override prevailing wage; prevailing wage is a floor, not a ceiling. If a collective bargaining agreement specifies a higher wage, the higher rate applies. Conversely, if an agreement specifies a lower rate, it is void as to prevailing wage projects. Prevailing wage is a non-waivable right—workers cannot agree to accept less.

Step 1: Document all wages, hours, and fringe benefits. Workers and unions should maintain payroll records, timesheets, pay stubs, and records of fringe benefit deductions or payments. Photograph identification badges showing job title and dates worked. Keep records of any communications with contractors about wage rates or payment. Retain copies of the project contract and the prevailing wage determination issued by the Department of Labor & Industry (available on the state website). If paid cash or by check with missing deductions, document the amount and date. These records are critical because the burden of proof initially rests with the complaint filer, though once a violation is shown, the contractor must prove they paid the correct rate.

Step 2: File an internal complaint with the contractor or project owner. Many prevailing wage violations occur due to administrative error or misunderstanding, and an internal complaint may resolve the issue quickly. Submit a written complaint to the contractor's payroll or human resources department and the project owner (the public entity), specifying the job classification, dates worked, hours claimed as unpaid, and the prevailing wage rate that should have been paid. Request a written response and documentation of wage calculations. If the contractor refuses or ignores the complaint, document this refusal and proceed to Step 3. Internal resolution is not required by law, but demonstrates good faith and may result in faster payment.

Step 3: File a formal complaint with the Pennsylvania Department of Labor & Industry, Prevailing Wage Unit. The Department can be reached at (717) 783-6447 or online at www.dli.pa.gov. File in writing with: (1) your name, address, and phone number; (2) the contractor's name and address; (3) the public project name, location, and public entity (e.g., school district, municipality); (4) dates of work and hours worked per day; (5) your job classification; (6) the prevailing wage rate that applied (cite the Department's prevailing wage determination); (7) wages actually paid; (8) the calculation of wages owed; (9) copies of pay stubs, timesheets, or other wage records. The complaint must be filed within a reasonable time; while no strict statute of limitations exists in the statute, federal courts have recognized a six-year period for contract-related wage claims, and the Department typically accepts complaints for work performed within the past 2-3 years. Include any union representative contact information if applicable.

Step 4: Expect the Department of Labor & Industry to investigate. The Department will contact the contractor and project owner, request their payroll records, cross-reference timesheets, and audit wage calculations. This process typically takes 30-90 days depending on complexity and contractor responsiveness. The Department may interview workers and other employees. If the Department finds a violation, it will issue a determination letter calculating back wages, fringe benefits owed, and penalties (typically 10% of the underpaid amount). The contractor is ordered to remit payment. If the contractor refuses, the Department may withhold future contract bids or pursue debarment. The worker may request an administrative appeal within 15 days of the determination letter if they disagree with the calculation.

Step 5: Consult an employment attorney if the Department's investigation is slow, the contractor refuses to pay, or the wage underpayment is substantial (over $5,000). An attorney specializing in prevailing wage or construction employment law can: file a civil action in state court for wage restitution plus attorney's fees and costs; represent the worker in an administrative appeal; negotiate a settlement with the contractor; and file a class action if multiple workers were underpaid. Pennsylvania law allows recovery of reasonable attorney's fees for prevailing wage claims, making legal action economically viable even for individual workers. Some unions and workers' organizations provide legal assistance at no cost to members.
