Marie Sandgathe

Marie Sandgathe serves as a key procurement lead within the W071 Endist Seattle office of the Department of the Army, overseeing the acquisition of heavy civil engineering and installation infrastructure projects critical to military readiness across the Pacific Northwest. Her work centers on the planning, solicitation, and management of construction, facility modernization, and environmental remediation contracts that sustain and enhance Army installations. She routinely handles complex, multi-year contracts requiring coordination with engineering disciplines, environmental regulators, and federal construction standards, ensuring compliance with DoD and Army Corps of Engineers protocols. Sandgathe maintains long-standing relationships with a core group of experienced contractors, including RDC JPA Architecture, FinCantieri Marine Repair LLC, Walsh Federal LLC, Absher Construction Co., and Big River Construction Inc. These partnerships reflect a preference for vendors with proven expertise in marine infrastructure, heavy construction, and federal facility rehabilitation. Her contracting patterns emphasize reliability, technical capability, and past performance over socioeconomic set-asides, fostering stable, performance-driven collaborations with contractors who consistently deliver mission-critical infrastructure under demanding operational conditions. Her procurement strategy reflects a 100% non-set-aside approach, indicating a focus on full and open competition rather than socioeconomic programs such as 8(a), HUBZone, or SDVOSB. This pattern underscores a mission-first orientation, prioritizing technical proficiency and capacity to execute large-scale civil works over socioeconomic preferences, even as it limits opportunities for small business participation under targeted programs. The agency’s procurement portfolio is anchored in heavy civil engineering, marine construction, and environmental restoration, with NAICS codes typically falling under 236 (Construction of Buildings), 237 (Heavy and Civil Engineering Construction), and 541330 (Engineering Services). Sandgathe’s expertise lies in managing complex projects involving coastal defense, hydraulic structures, dredging, and installation resilience, requiring deep familiarity with federal construction codes, environmental compliance, and military installation standards.
