Common contracting fraud schemes

Federal contractors must meet precise specifications — from highway materials testing to cybersecurity certifications on defense systems. Fraud includes substituting substandard materials, falsifying test results, inflating labor hours, cross-charging costs between contracts, and misrepresenting small-business or veteran-owned status.

Why insiders matter

Auditors rarely see what happens on a job site or in a manufacturing line. Quality assurance staff, project managers, and subcontractors often hold the key facts. False Claims Act cases in construction and defense have returned hundreds of millions to the Treasury.

3

Materiality and certification

Many contracts require periodic certifications of compliance. Submitting a claim for payment while knowingly failing to meet contract requirements can be false under the FCA. The government does not need to prove every penny was lost — material false statements tied to payment requests are enough for enforcement to begin.

Next steps for whistleblowers

If you have firsthand knowledge of fraud on a federal contract, preserve evidence lawfully and speak with qui tam counsel. First-to-file and public disclosure rules apply, so delay can cost you the ability to bring a case.

Key takeaways

  • Contract requirements, certifications and payment claims should be compared together.
  • False testing, cost allocation and eligibility certifications can raise FCA concerns.
  • A contract dispute or performance defect alone does not establish fraud.
