Mary K. Thomsen

Mary K. Thomsen serves as a Contract Specialist within the W071 Endist Omaha office under the Department of the Army, where she plays a pivotal role in executing mission-critical acquisitions to sustain and modernize military infrastructure. She manages a diverse portfolio of contracts spanning engineering services, technical support, and heavy civil construction, ensuring alignment with the Army’s strategic priorities in nuclear deterrence, base readiness, and utility corridor development. Her work directly supports the delivery of hardened facilities and operational environments essential to national defense, employing full and open competition alongside targeted small business set-asides to meet statutory and mission-driven objectives. Thomsen maintains consistent working relationships with a core group of established contractors including JOHN BOWMAN, INC., PAF ELECTRICAL, INC., HENDRICKSON TRANSPORTATION LLC, PERINI MANAGEMENT SERVICES, INC., and WASHINGTON EQUIPMENT MANUFACTURING COMPANY, INC. These partnerships reflect a preference for vendors with proven expertise in military-grade construction, electrical systems integration, and transportation logistics. Her contracting approach emphasizes performance-based outcomes, rigorous compliance with FAR provisions, and long-term vendor reliability to ensure mission continuity across high-stakes defense installations. Her procurement patterns demonstrate a balanced commitment to socioeconomic goals, with nearly one-third of her awards designated as Total Small Business Set-Asides under FAR 19.5, and additional participation from 8(a) and Women-Owned Small Businesses. While the majority of her acquisitions remain open to all competitors, her deliberate use of set-asides underscores a strategic effort to broaden vendor diversity and strengthen the defense industrial base through inclusive contracting practices. Thomsen’s technical focus centers on NAICS 541990 (Professional, Scientific, and Technical Services) and 541330 (Engineering Services), with significant activity in 237990 (Other Heavy and Civil Engineering Construction). She routinely procures specialized services such as site engineering, facility modernization, utility system upgrades, and custom software development for defense infrastructure management, reflecting deep domain expertise in military construction and operational support systems.
