Marlene Haussler

Marlene Haussler serves as a Contract Specialist (Contractor) within the DSC Contracting Services Division of the National Park Service, where she plays a pivotal role in managing the acquisition lifecycle for infrastructure preservation and modernization projects across America’s protected lands. Her responsibilities include developing, soliciting, awarding, and administering contracts for architectural, engineering, and construction services critical to rehabilitating historic structures, upgrading utility systems, and enhancing visitor facilities in ecologically sensitive and remote locations. She ensures compliance with federal procurement regulations while aligning acquisitions with the agency’s mission to sustain the nation’s cultural and natural heritage through resilient, long-term infrastructure investments. Haussler maintains strong, recurring relationships with leading firms specializing in environmental and civil infrastructure, 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 established, technically proficient vendors with demonstrated experience in federal historic preservation and environmental compliance. Her procurement approach emphasizes collaborative contract management, rigorous performance oversight, and technical alignment with NPS preservation standards. A consistent advocate for small business participation, Haussler prioritizes Total Small Business Set-Asides under FAR 19.5, which account for half of her acquisitions, and regularly utilizes HUBZone set-asides to support economically disadvantaged communities. Her contracting patterns reflect a deliberate strategy to expand opportunities for small, locally rooted firms while maintaining high standards of technical delivery. Her procurement focus is concentrated in NAICS 541310 (Architectural Services) and 541330 (Engineering Services), with significant activity in 236220 (Commercial and Institutional Building Construction). She specializes in procuring services related to historic structure rehabilitation, civil engineering for water and sewer systems, and adaptive reuse construction—ensuring that all projects meet NPS preservation guidelines and environmental regulations.
