Harold Williamson

Harold Nmi Williamson serves as a key procurement lead within the W075 Endist Sacramento office under the Department of the Army, overseeing the acquisition of engineering, surveying, and architectural services critical to sustaining and modernizing military infrastructure across the Western United States. Responsible for managing the full lifecycle of contract actions—from requirements development to award and administration—he ensures alignment with Army installation readiness goals, environmental compliance standards, and facility lifecycle management priorities. His portfolio primarily supports civil works, construction oversight, and land asset stewardship through technical service contracts that enable mission-critical infrastructure resilience. Williamson maintains consistent working relationships with a core group of established contractors, including Mckenzie Construction & Site Development LLC, DMZ Builders, Far West Contractors Corp, and Aleut Construction LLC, all of which possess proven expertise in military facility support and western regional construction environments. These partnerships reflect a preference for vendors with demonstrated capability in complex site development, environmental remediation, and installation-scale engineering services. His contracting patterns emphasize reliability, past performance, and regional familiarity, fostering long-term vendor collaboration while maintaining competitive acquisition practices. A strong advocate for small business participation, Williamson consistently allocates over 43% of his acquisitions as total small business set-asides under FAR 19.5, reflecting a deliberate commitment to socioeconomic contracting goals. While no other specific set-aside categories dominate, his portfolio actively supports small business growth through transparent solicitation practices and targeted outreach to qualified firms. His technical focus centers on NAICS 541330 (Engineering Services), which accounts for over 80% of his acquisitions, supplemented by architectural and surveying services under NAICS 541310 and 541370. He procures professional services related to geotechnical analysis, land surveying, infrastructure design, and environmental planning—domains requiring certified professionals and adherence to Army Corps of Engineers standards and federal construction codes.
