Mary Spiess

Mary E. Spiess serves as a Contract Specialist at the W4GG Hq US Army Tacom, where she plays a pivotal role in executing the lifecycle acquisition and sustainment of ground combat and support vehicle systems. Responsible for the full spectrum of contracting activities—from solicitation and evaluation to award and administration—she ensures compliance with federal acquisition regulations while advancing the agency’s mission to maintain technological superiority in armored and tactical wheeled platforms. Her portfolio primarily consists of engineering services contracts supporting vehicle modernization, survivability enhancements, and integrated logistics solutions for Department of Defense ground systems. Spiess maintains consistent procurement relationships with a core group of specialized contractors, including Schutt Industries of Clintonville, Wis., Inc., ONTIC ENGINEERING & MANUFACTURING, INC, A&M AEROSTRUCTURES, INC., and BOWHEAD AVIONICS MANUFACTURING, LLC. These partnerships reflect a focus on high-precision engineering, avionics integration, and advanced manufacturing capabilities critical to vehicle systems sustainment. Her working relationships are characterized by technical rigor, long-term collaboration, and a preference for vendors with proven expertise in military-grade engineering and systems integration. Notably, Spiess’s contracting activity is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic emphasis on technical capability over socioeconomic preferences, aligning with the high-stakes, mission-critical nature of TACOM’s vehicle modernization programs. While small business participation is not formally prioritized in her portfolio, all procurements remain compliant with FAR requirements and are evaluated solely on technical merit and performance history. Her procurement focus is exclusively under NAICS 541330 (Engineering Services), underscoring deep specialization in technical engineering support for armored vehicle systems. She consistently acquires services related to mechanical design, survivability analysis, powertrain integration, and digital engineering solutions—domain expertise critical to sustaining the Army’s fleet of tactical platforms under evolving battlefield demands.
