About the OIG Hotline

The Architect of the Capitol, Office of Inspector General (OIG) is responsible for the prevention and detection of fraud, waste and/or abuse (FW&A) in AOC programs, and/or involving AOC personnel.

The purpose of the AOC's OIG Hotline is to receive complaints of fraud, waste, or abuse in AOC programs and operations including mismanagement or violations of law, rules or regulations by AOC employees, contractors or program participants. Examples of FW&A violations include:

  • Contract fraud, including contract mischarging by the contractor
  • Kick-backs and bid rotation by competing contractors
  • Contractors failing to pay full wages to employees
  • Bribery and acceptance of gratuities by government employees
  • Significant mismanagement and waste of funds
  • Conflicts of interest
  • Travel fraud
  • Gross abuse of employee time and attendance reporting
  • Abuse of authority
  • Theft or abuse of government property, including private (unofficial) use of government computers
  • Computer crime
Minor incidents, such as, irregular time and attendance abuse, or one-time misuse of government property should be reported to management. Personnel matters involving requests for individual relief should be handled through the appropriate grievance process with AOC management.
