Sue Mayo

Sue Mayo serves as the primary procurement lead for the National Park Service’s Pwr Olym MABO (140P83), overseeing mission-critical infrastructure acquisitions across remote and environmentally sensitive park sites. Her role centers on ensuring the timely delivery of resilient transportation, utility, and facility systems that support public safety, environmental stewardship, and visitor access. She manages a diverse portfolio of construction and specialized equipment contracts, with a focus on projects requiring technical precision in harsh or isolated conditions. Mayo’s acquisitions align with the agency’s strategic imperatives to modernize aging infrastructure while adhering to federal sustainability and resilience standards. Mayo maintains a consistent working relationship with 504 STRONG ENTERPRISES LLC, a key vendor providing specialized construction and maintenance services tailored to National Park Service needs. Her contracting patterns reflect a preference for long-term, performance-based partnerships with firms experienced in remote-site logistics, heavy civil construction, and mission-critical equipment integration. She prioritizes vendors with demonstrated expertise in navigating complex environmental regulations and coordinating with federal land management teams. Her procurement strategy reflects a strong commitment to socioeconomic diversity, with over half of her acquisitions structured as total small business set-asides under FAR 19.5. An additional 6.3% are reserved for service-disabled veteran-owned small businesses, demonstrating targeted support for veteran entrepreneurs. While nearly half of her contracts are open to all competitors, her consistent use of small business set-asides underscores a deliberate effort to expand opportunities for underserved contractors within the federal infrastructure sector. Mayo’s primary technical focus lies in NAICS 237310 (Highway, Street, and Bridge Construction), 333120 (Construction Machinery Manufacturing), and 333914 (Pumping Equipment Manufacturing), reflecting her domain expertise in civil infrastructure and mechanical systems. She routinely procures heavy-duty equipment, water and wastewater systems, and specialized machinery designed for rugged park environments, ensuring operational continuity in areas with limited access and extreme weather exposure. Her work bridges engineering requirements with practical field implementation, supporting the NPS’s mission to preserve natural resources through durable, sustainable infrastructure.
