Dariel D. Mayfield

Dariel D. Mayfield serves as a key procurement professional within the Federal Bureau of Investigation’s Office of Science and Technology, supporting the modernization of forensic science and digital intelligence capabilities. Responsible for managing complex acquisitions aligned with the FBI’s mission to enhance evidence analysis and secure communications, Mayfield oversees contracts for advanced analytical instrumentation, laboratory equipment, and specialized technical services. Their work directly enables the agency’s strategic priorities in forensic laboratory modernization, cyber-enabled investigations, and the integrity of digital evidence systems, ensuring that procurement decisions align with federal standards and operational exigencies. Mayfield maintains primary contracting relationships with VISTA OUTDOOR SALES LLC and SOUTHERN POLICE EQUIPMENT COMPANY, INC., both of which supply mission-critical forensic and field equipment. These partnerships reflect a focus on durable, compliant, and technologically advanced hardware tailored to law enforcement and forensic science applications. While these two vendors dominate the portfolio, Mayfield also engages a broader network of specialized suppliers to support niche technical requirements, demonstrating a balanced approach between established vendors and responsive niche providers. A significant portion of Mayfield’s acquisitions—28.6%—are structured as Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate commitment to fostering small business innovation within the forensic and technical services sector. While the majority of procurements remain open competition, the consistent use of small business set-asides underscores a strategic effort to diversify the supplier base and promote socioeconomic inclusion in high-technology federal contracting. The procurement portfolio is concentrated in NAICS 332710 (Machine Shops) for precision forensic equipment manufacturing, complemented by significant activity in 541990 (Other Professional, Scientific, and Technical Services) and 611430 (Professional Training), indicating a strong demand for custom instrumentation, technical support services, and workforce development. Mayfield’s expertise spans the integration of advanced analytical tools, secure data handling systems, and specialized training programs essential to maintaining the FBI’s forensic and digital investigative edge.
