Darin S Barnes

Darin S. Barnes serves as a Contract Negotiator responsible for facilitating the execution of complex procurement actions across a diverse range of technical and specialty trade services. In this role, he ensures compliance with federal acquisition regulations while balancing mission needs with fiscal responsibility and socioeconomic objectives. His procurement portfolio centers on negotiated contracts requiring detailed technical evaluation and risk mitigation, particularly in construction, industrial maintenance, and specialized manufacturing sectors. Barnes plays a critical role in advancing the agency’s acquisition strategy by structuring solicitations that promote competition, ensure contractor performance, and uphold contractual integrity. While specific contractor names are not available, Barnes maintains consistent engagement with a broad spectrum of vendors, including small businesses, specialty trade contractors, and manufacturers of industrial equipment. His negotiation patterns reflect a preference for performance-based contracting and clear statement of work definitions, fostering transparent, results-driven vendor relationships. He routinely works with firms capable of delivering high-complexity, low-volume goods and services requiring precise technical specifications and quality assurance protocols. Barnes demonstrates a strong commitment to small business participation, with nearly 14% of his contracting activity directed toward small business set-asides under FAR 19.5, including a notable 1.7% allocated to 8(a) competed contracts. The overwhelming majority of his awards—86.2%—are conducted without set-aside, indicating a primary focus on full and open competition, yet he consistently prioritizes socioeconomic goals where appropriate, aligning with federal mandates to expand opportunities for disadvantaged businesses. His primary procurement focus lies in NAICS 238160 (Roofing Contractors) and 238990 (All Other Specialty Trade Contractors), reflecting extensive involvement in facility maintenance and infrastructure support. He also actively procures specialized industrial components under NAICS 336413 and 335311, demonstrating expertise in aerospace parts and power transformer manufacturing. His technical domain knowledge extends to commercial and industrial machinery repair under NAICS 811310, underscoring a nuanced understanding of maintenance-intensive, mission-critical supply chains.
