Samantha Johanson

Samantha Johanson serves as the primary contracting lead for the W07V Endist Rock Island, a division of the U.S. Army Corps of Engineers under the Department of the Army. She oversees the acquisition of civil infrastructure projects critical to national water resource management, including flood control systems, navigation locks, dams, and riverine maintenance operations. Her role centers on executing full lifecycle procurement activities—from market research and solicitation development to contract award and administration—ensuring alignment with federal engineering standards and mission-critical readiness goals. Johanson specializes in complex, large-scale construction and engineering services requiring interdisciplinary coordination and strict compliance with federal construction codes and environmental regulations. She maintains consistent, long-term relationships with key contractors including J.F. Brennan Company, Inc., Sealevel Construction Inc., Johnpac, LLC, Kiewit Infrastructure West Co., and Ellicott Dredge Technologies, LLC. These partnerships reflect a preference for established firms with proven expertise in heavy civil works, dredging, and hydraulic infrastructure. Johanson’s contracting approach emphasizes performance-based outcomes, technical compliance, and contractor reliability, fostering collaborative, risk-managed engagements that support multi-year project pipelines. Her procurement strategy prioritizes open competition, with 62.2% of awards issued without set-asides, yet she actively supports small business participation through Total Small Business Set-Asides (32.4%) and 8(a) competed awards (5.4%). This balanced approach ensures market competitiveness while fulfilling statutory obligations to promote socioeconomic inclusion in federal infrastructure contracting. Johanson’s primary procurement focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction), reflecting her domain expertise in large-scale earthworks, structural concrete, and water resource systems. She also procures engineering services (541330), landscaping for environmental mitigation (561730), and specialized equipment such as dredging machinery and analytical instrumentation (334516). Her technical acumen spans hydraulic modeling, geotechnical construction, and environmental compliance, making her a key steward of resilient public infrastructure across the Upper Mississippi River basin.
