Dayon T Santos

Dayon Tre Santos serves as a key procurement professional within the W071 Endist Portland office of the U.S. Army Corps of Engineers, supporting the Department of the Army’s mission to sustain critical civil infrastructure across the Pacific Northwest. Responsible for managing complex acquisitions in heavy civil engineering and facility maintenance, Santos oversees contracts for navigational infrastructure, hydropower system upgrades, and environmental compliance projects. Their work ensures operational readiness of federal waterways and defense-related facilities through strategic sourcing of construction, engineering, and specialized technical services, aligning acquisitions with federal regulations and mission-critical timelines. Santos maintains longstanding relationships with leading contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, AECOM B&V PORTLAND AE JV, CORNFORTH-GANNETT FLEMING, STANTEC CONSULTING SERVICES INC., and TETRA TECH, INC. These partnerships reflect a preference for firms with proven expertise in heavy civil construction, water resources engineering, and environmental remediation. The contracting approach emphasizes performance-based outcomes, technical rigor, and sustained collaboration with vendors capable of delivering multi-year, mission-critical infrastructure solutions under stringent regulatory frameworks. While the majority of acquisitions—88.9%—are conducted without set-asides, Santos consistently allocates 11.1% of contracting opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to small business participation. This pattern supports broader Army goals of economic inclusivity while maintaining technical capacity, with no current use of 8(a), HUBZone, or SDVOSB set-asides, indicating a focus on broad-based small business eligibility rather than targeted socioeconomic programs. The procurement portfolio is heavily concentrated in NAICS 236220 (Commercial and Institutional Building Construction) and 237990 (Other Heavy and Civil Engineering Construction), reflecting core work in structural, hydraulic, and geotechnical infrastructure. Additional activity includes procurement of construction machinery, janitorial services, and equipment leasing, underscoring a holistic approach to facility sustainment and operational support across federal defense and water resource assets.
