Product Service Code (PSC) R424 encompasses professional expert witness services across various specialized domains. These services involve providing specialized, high-level professional testimony, analysis, and consultation for government agencies during legal proceedings, investigations, and administrative hearings. Expert witnesses typically offer in-depth technical, scientific, medical, economic, psychological, or forensic expertise to support complex government litigation and decision-making processes.
Federal contract awards under PSC R424 demonstrate a diverse range of expert witness services, predominantly from small businesses and sole proprietorships. Most contracts range from $4,000 to $250,000, with performance periods typically spanning one to five years. Frequent awardees include medical professionals providing vaccine injury compensation program case reviews, forensic scientists offering DNA analysis testimony, and specialized consultants supporting the U.S. Attorney's Offices and various federal agencies like the Department of Health and Human Services, Internal Revenue Service, and Department of Justice. Contracts are predominantly time and materials or firm fixed-price, with no set-aside designation being most common, though total small business set-asides are also prevalent.
Recent federal contract opportunities under PSC R424 include the Social Security Administration's solicitation for Vocational Expert Consulting Services, seeking professionals to provide expert witness testimony for disability determinations, and the Department of Veterans Affairs' intent to sole-source certification review hearings. The Federal Bureau of Investigation has also posted a request for information for research contractor support, specifically seeking expert psychological services to support counterintelligence investigations. These opportunities emphasize the need for highly specialized professionals who can provide sophisticated, nuanced expertise across various government contexts.
