Katharina O'Reilly

Katharina O’Reilly serves as a key procurement professional within Ner Services Mabo (43000), a division of the National Park Service responsible for maintaining the physical integrity of federally protected lands and historic sites. She manages a diverse portfolio of construction, environmental, and facility support contracts, ensuring operational readiness through timely acquisition of infrastructure repair services, climate-resilient upgrades, and heritage preservation solutions. Her work directly supports the agency’s mission to sustain visitor facilities while complying with federal environmental and historic preservation standards, requiring deep familiarity with technical specifications for public works and adaptive reuse projects. She maintains active relationships with a stable cohort of contractors including CLASSIC SITE SOLUTIONS INC, CCI CONSTRUCTION AND ENERGY SERVICES, LLC, and REAGENT WORLD, INC., specializing in plumbing, HVAC, and environmental compliance services. Her contracting patterns reflect a preference for established vendors with proven experience in federal park infrastructure, often engaging firms with demonstrated expertise in historic masonry, stormwater management, and energy-efficient retrofitting. These partnerships are characterized by repeat engagements and performance-based contract structures that prioritize long-term reliability over short-term cost savings. O’Reilly exhibits a balanced approach to socioeconomic contracting, with approximately half of her acquisitions set aside for small businesses under FAR 19.5, and the remainder open to all competitors. This reflects a deliberate strategy to foster small business participation without compromising technical rigor or project timelines. Her contracting practices consistently align with the National Park Service’s goals of inclusive economic opportunity and workforce development in rural and underserved communities. Her primary procurement focus lies in NAICS 238220 (plumbing, heating, and air-conditioning), 212311 (dimension stone mining and quarrying), and 337212 (custom architectural woodwork), indicating deep specialization in materials and systems critical to historic preservation and sustainable infrastructure. She routinely procures custom millwork, natural stone finishes, septic system upgrades, and administrative support services essential to park operations, demonstrating technical fluency in both traditional craftsmanship and modern environmental compliance standards.
