Harron Elloso

Harron Elloso serves as a Contract Specialist within the W071 Endist Portland office under the Department of the Army, where he plays a pivotal role in executing complex procurement actions that sustain critical civil infrastructure across the Pacific Northwest. His responsibilities encompass the full lifecycle management of contracts for heavy civil engineering, environmental compliance, and facility maintenance services essential to federal waterways, hydropower systems, and flood control infrastructure. Elloso specializes in acquiring technical services and construction solutions under FAR Part 36, ensuring alignment with Army Corps of Engineers standards and federal environmental regulations. His acquisitions directly support operational readiness and long-term resilience of defense-related water infrastructure. Elloso maintains consistent working relationships with leading contractors in the civil engineering and technical services sectors, 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 large-scale infrastructure projects, environmental remediation, and hydrological engineering. His contracting approach emphasizes performance-based outcomes, rigorous technical evaluation, and long-term vendor reliability, fostering collaborative, mission-driven relationships grounded in compliance and accountability. Elloso demonstrates a strong commitment to small business participation, with 42.9% of his acquisitions structured as Total Small Business Set-Asides under FAR 19.5. While the majority of his portfolio remains open to all competitors, he actively prioritizes opportunities for small businesses with relevant technical capabilities in civil construction and engineering services, ensuring equitable access without compromising mission requirements. His socioeconomic contracting patterns reflect a balanced approach—supporting small business growth while maintaining the technical rigor needed for critical federal infrastructure. His procurement focus is heavily concentrated in NAICS 237990 (Other Heavy and Civil Engineering Construction), complemented by significant activity in electrical, concrete, and plumbing contractors. He routinely procures services related to dam and levee maintenance, channel stabilization, surveying, and hydraulic system upgrades, demonstrating deep domain expertise in federal water resource infrastructure and its operational sustainment.
