John Warner

John Warner serves as Supervisory Contract Specialist within the DSC Contracting Services Division of the National Park Service, overseeing the full lifecycle of construction and infrastructure procurement for America’s national parks. He manages complex acquisitions for the rehabilitation of historic structures, modernization of visitor facilities, and upgrades to critical utility systems in ecologically sensitive and remote locations. His portfolio centers on capital improvement projects requiring precise compliance with federal preservation standards, environmental regulations, and federal construction codes. Warner ensures that contracting actions align with the agency’s mission to sustain the nation’s cultural and natural heritage through resilient, long-term infrastructure investments. He maintains enduring relationships with leading engineering and construction firms including AECOM Technical Services, Inc., Vanasse Hangen Brustlin, Inc., Johnson, Mirmiran & Thompson, Inc., HDR Engineering Inc., and McKenzie Construction & Site Development LLC. These partnerships reflect a preference for firms with proven expertise in historic preservation, civil engineering, and site-specific construction in protected environments. Warner’s approach emphasizes performance-based contracting, rigorous technical evaluations, and collaborative pre-solicitation engagement to ensure contractor readiness and project success. Warner’s procurement activity is exclusively conducted under full and open competition, with no set-asides designated for 8(a), HUBZone, SDVOSB, or other socioeconomic programs. While small business participation is not formally structured through set-asides, he encourages subcontracting opportunities through prime contractor obligations and performance-based incentives, maintaining compliance with FAR Part 19 while prioritizing technical capability and mission alignment. His primary procurement focus lies in NAICS 238140 (Masonry Contractors), 238160 (Roofing Contractors), and 236220 (Commercial and Institutional Building Construction), reflecting deep specialization in masonry restoration, waterproofing and roofing systems, and adaptive reuse of historic buildings. He routinely procures services involving structural stabilization, asbestos abatement, historic material replication, and energy-efficient retrofits—all tailored to the unique constraints of National Park Service sites.
