John Mack

John E. Mack serves as a key procurement professional within Naval Facilities Engineering Systems Command Southeast (NAVFACSE) under contract code N69450, supporting the Department of the Navy’s mission to deliver resilient, mission-critical infrastructure across the Southeastern U.S. and overseas operational areas. He manages the acquisition lifecycle for complex construction and utilities projects, primarily overseeing commercial and institutional building construction, water and sewer infrastructure, and base operations support systems. His work directly enables naval readiness by ensuring timely delivery of facilities that meet stringent military standards for durability, safety, and operational continuity. Mack maintains consistent working relationships with a core group of experienced federal contractors, including BL Harbert International LLC, Walsh Federal LLC, Sauer Construction, LLC, McKenzie Construction & Site Development LLC, and Kira Aviation Services LLC. These partnerships reflect a preference for firms with proven track records in large-scale, mission-sensitive construction and infrastructure modernization. His procurement approach emphasizes performance-based contracting, integrated project delivery, and rigorous compliance with federal construction codes and Navy-specific engineering requirements. Mack’s contracting activity reflects a 100% non-set-aside profile, indicating a strategic focus on full and open competition rather than socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. While small business participation is not formally prioritized in his portfolio, the nature of the work often attracts qualified small and mid-sized firms through open solicitations and subcontracting opportunities under prime contracts. His primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), accounting for 75% of activity, followed by water and sewer infrastructure (237110) and water supply systems (221310). He specializes in acquiring turnkey construction services, utility upgrades, and facility modernization projects requiring coordination with environmental, electrical, and structural engineering disciplines, demonstrating deep expertise in defense infrastructure acquisition.
