Tanya Shields

Tanya Pat P. Shields serves as a Purchasing Agent responsible for managing the acquisition of specialized equipment and technical services critical to operational continuity. In this role, she executes procurements in full compliance with the Federal Acquisition Regulation, ensuring timely delivery of mission-critical goods while maintaining fiscal accountability and regulatory adherence. Her portfolio primarily encompasses analytical instrumentation, precision equipment maintenance, and laboratory support services, reflecting a technical procurement focus aligned with scientific and industrial operational needs. She works within a structured acquisition framework to evaluate vendor proposals, negotiate terms, and administer contracts with an emphasis on efficiency and compliance. While specific contractor names are not available, her procurement patterns indicate a preference for established suppliers with demonstrated capability in high-precision manufacturing and technical repair services. She engages with a broad base of vendors, including both large-tier manufacturers and niche service providers, prioritizing technical expertise, quality assurance, and delivery reliability over sole-source arrangements. Her contracting approach emphasizes competitive bidding and performance-based outcomes, fostering transparent and accountable vendor relationships grounded in FAR-compliant processes. Tanya’s set-aside usage is overwhelmingly focused on open competition, with 96.3% of acquisitions conducted without socioeconomic set-asides. A modest but consistent portion—3.2%—is reserved for Total Small Business Set-Asides under FAR 19.5, and a minimal 0.5% is allocated to 8(a) competed contracts. This pattern suggests a procurement strategy that prioritizes broad market competition while maintaining a foundational commitment to small business inclusion, particularly where market conditions support it. Her primary NAICS focus lies in 811219 (Other Electronic and Precision Equipment Repair and Maintenance) and 334516 (Analytical Laboratory Instrument Manufacturing), reflecting deep expertise in procuring calibrated instruments, diagnostic tools, and precision maintenance services. Additional activity in NAICS 511210 and 325998 indicates procurement of laboratory software solutions and specialized chemical preparations. Her domain knowledge spans technical specifications for scientific instrumentation, calibration standards, and maintenance protocols, positioning her as a specialist in procuring high-reliability, low-volume technical goods.
