Brian K. Lewallen

Brian K. Lewallen serves as a procurement professional responsible for managing complex acquisitions in advanced instrumentation and analytical technologies. He plays a critical role in executing the agency’s mission to acquire high-precision scientific equipment and measurement systems, ensuring compliance with federal acquisition regulations and technical performance standards. His portfolio primarily encompasses the procurement of laboratory instruments, electrical signal measurement devices, and specialized software solutions supporting scientific research and quality control. Lewallen’s work directly supports mission-critical operations requiring calibrated, reliable, and interoperable technical systems. His contractor relationships are characterized by engagement with manufacturers of analytical instrumentation and niche technology providers, particularly those capable of delivering custom or highly specialized equipment. While no single vendor dominates his award portfolio, he consistently collaborates with firms possessing ISO-certified manufacturing processes and proven expertise in calibration, validation, and compliance with industry standards such as ASTM and NIST guidelines. His procurement approach emphasizes technical evaluation, lifecycle cost analysis, and vendor performance history to ensure long-term system reliability. Lewallen demonstrates a strong commitment to small business participation, with over one-third of his acquisitions structured as total small business set-asides under FAR 19.5. His contracting patterns reflect a deliberate preference for small business vendors capable of meeting stringent technical requirements, with minimal use of other socioeconomic set-asides such as 8(a) or HUBZone. This focus underscores a strategic alignment with the agency’s goal of fostering innovation through partnerships with agile, technically proficient small manufacturers. His primary procurement focus centers on NAICS codes related to analytical laboratory instrument manufacturing (334516), other measuring and controlling device manufacturing (334519), and instrument manufacturing for electrical signal measurement (334515). He routinely acquires precision instruments used in environmental testing, materials analysis, and laboratory automation, demonstrating deep technical familiarity with sensor technologies, data acquisition systems, and calibration protocols essential to scientific and regulatory operations.
