Rachel Dyer

Rachel Dyer serves as the primary contracting lead for the DSC Contracting Services Division within the National Park Service, overseeing the acquisition of critical infrastructure and engineering services essential to preserving and modernizing America’s national parks. She manages a diverse portfolio of procurements focused on the rehabilitation of historic structures, upgrading utility systems, and constructing resilient civil infrastructure across ecologically sensitive and remote landscapes. Her work directly supports the agency’s mission to safeguard cultural resources while enhancing visitor safety and accessibility through strategic contracting aligned with federal acquisition regulations. Dyer maintains long-standing relationships with top-tier engineering and construction firms including AECOM Technical Services, Vanasse Hangen Brustlin, Johnson, Mirmiran & Thompson, HDR Engineering, and McKenzie Construction & Site Development. These partnerships reflect a preference for experienced, multi-disciplinary contractors capable of delivering complex civil, environmental, and architectural services under stringent environmental and historic preservation standards. Her contracting approach emphasizes performance-based outcomes, rigorous technical evaluation, and collaborative project execution with firms possessing proven expertise in federal land management contexts. Her procurement patterns show a strong preference for open competition, with 81% of awards issued without set-aside restrictions. While small business participation remains secondary, she consistently allocates approximately 16.7% of contracts under Total Small Business Set-Asides and a smaller but intentional portion to 8(a) competed awards, demonstrating measured but deliberate support for socioeconomic programs without compromising technical requirements. Dyer’s portfolio is dominated by NAICS 541330 (Engineering Services), 237310 (Highway, Street, and Bridge Construction), and 541620 (Environmental Consulting Services), reflecting deep specialization in civil infrastructure, environmental remediation, and site-specific engineering design. She routinely procures services related to water and sewer system upgrades, historic structure rehabilitation, erosion control, and geotechnical assessments, requiring contractors with niche expertise in federal land use regulations and sustainable construction practices.
