Mary Seiner

Mary Seiner serves as the primary contracting professional for the U.S. Army Engineer District Walla Walla, overseeing the acquisition of critical civil and military infrastructure support services and specialized equipment. She manages a diverse portfolio of contracts aligned with the district’s mission to maintain water resource systems, flood control structures, navigation channels, and hydropower facilities across the Pacific Northwest. Her procurement activities focus on engineering support, facility maintenance, and technical equipment procurement, ensuring operational readiness and regulatory compliance for federal infrastructure assets. Seiner’s work directly enables the district’s ability to deliver safe, resilient, and mission-critical public works. She maintains strong, recurring relationships with a core group of experienced contractors including JR MERIT, INC., NORTHBANK CIVIL AND MARINE, INC., NORTH WIND GENERAL CONTRACTORS LLC, KNIGHT CONST. & SUPPLY, INC., and TRANSCO INDUSTRIES, INC. These partnerships reflect a preference for vendors with proven expertise in marine construction, structural metal fabrication, crane and hoist systems, and inland waterway logistics. Seiner consistently engages these firms for complex, technical procurements requiring specialized labor, equipment, and regulatory knowledge, fostering long-term collaboration grounded in performance reliability and technical proficiency. Seiner demonstrates a balanced approach to socioeconomic contracting, with nearly half of her acquisitions structured as total small business set-asides under FAR 19.5, while a significant portion remains open to all competitors. She also actively utilizes 8(a) competed set-asides, reflecting a deliberate commitment to expanding opportunities for disadvantaged small businesses without compromising mission needs. Her contracting patterns align with Army directives to promote equitable access while maintaining competitive rigor and technical quality. Her primary procurement focus centers on NAICS 561720 (janitorial and sanitation services for federal installations), 332312 (fabricated structural metal), 333923 (overhead crane systems), 335313 (switchgear and switchboard apparatus), and 483211 (inland water freight transportation). These categories underscore her technical expertise in procuring specialized industrial equipment, structural components, and logistics support essential to the operation and maintenance of hydropower and navigation infrastructure.
