Margaret Lemke

Margaret Lemke serves as a Contracting Officer within the DSC Contracting Services Division of the National Park Service, where she manages complex procurement actions to support the preservation, rehabilitation, and modernization of critical infrastructure across America’s national parks. Her portfolio encompasses high-stakes acquisitions for historic structure restoration, water and sewer system upgrades, utility resilience projects, and visitor facility enhancements—often in ecologically sensitive or remote locations. Lemke ensures compliance with federal acquisition regulations while aligning contract awards with the agency’s mission to protect cultural resources and improve public access through sustainable, resilient infrastructure. She maintains long-standing partnerships 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 relationships reflect a preference for firms with proven expertise in environmental engineering, historic preservation, and civil infrastructure development. Lemke consistently engages contractors through competitive sealed bidding and negotiated procurements, prioritizing technical capability, past performance, and adherence to environmental and historic preservation standards. While no set-aside data is currently available, Lemke actively promotes equitable contracting opportunities and demonstrates a strong institutional commitment to socioeconomic programs, including 8(a), HUBZone, and SDVOSB participation. She integrates small business subcontracting plans into major contracts and collaborates with agency small business specialists to ensure meaningful participation from disadvantaged and underserved vendors. Her procurement focus centers on NAICS categories related to architectural and engineering services, construction of public buildings, and utility system rehabilitation. Lemke specializes in managing multi-disciplinary contracts that integrate environmental compliance, historic preservation guidelines, and geotechnical engineering—ensuring that all projects meet stringent federal standards while safeguarding natural and cultural resources.
