Mark C. Wirtz

Mark C. Wirtz serves as a key procurement lead within the Department of the Army’s 0409 Aq Hq Contract office, overseeing the acquisition of critical infrastructure support services for U.S. Army garrisons and overseas installations, particularly in Europe. His responsibilities include managing complex contracts for facility maintenance, specialized construction, and logistics equipment servicing to ensure operational readiness and installation resilience. He handles a diverse portfolio of acquisitions spanning commercial and industrial equipment repair, transportation services, and mission-critical infrastructure support, ensuring compliance with federal procurement regulations and alignment with Army sustainment priorities. Wirtz maintains consistent working relationships with a select group of international and domestic contractors, including ING. LUDWIG FREITAG ELEKTRO-GMBH & CO. KG, BFRENCH CONSULTING LLC, APC AG, FREUND LANDMASCHINEN GMBH & CO. KG, and BB GOVERNMENT SERVICES GMBH. These partnerships reflect a focus on specialized European-based vendors with expertise in industrial maintenance, electrical systems, and vehicle logistics support. His contracting approach emphasizes technical proficiency, reliability, and proven performance in austere or deployed environments, often favoring long-term vendor relationships built on demonstrated capability rather than competitive bidding alone. Wirtz’s procurement activity shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This indicates a strategic preference for selecting the most qualified vendors based on technical merit and operational suitability, regardless of business size or certification status. While small business participation is not formally prioritized, his contracting decisions remain fully compliant with FAR requirements and reflect a mission-driven focus on capability over socioeconomic criteria. His primary procurement focus centers on NAICS 811310 for commercial and industrial machinery repair, NAICS 485510 for charter bus services, and NAICS 532111 for passenger car rental—all critical to sustaining garrison mobility and equipment readiness. He also procures specialized equipment under NAICS 333244 and 333111, demonstrating deep domain expertise in military logistics infrastructure, vehicle fleets, and industrial maintenance systems essential to overseas operational continuity.
