Sarah A. Langston

Sarah A. Langston serves as a Contract Specialist within the USDA Forest Service-spoc Software, where she manages the acquisition of critical civil engineering, environmental remediation, and land management support services essential to national forest stewardship. Her role encompasses the full lifecycle of procurement—from market research and solicitation development to contract award and administration—ensuring compliance with federal regulations and alignment with the agency’s mission to enhance infrastructure resilience and ecological restoration. She routinely handles complex, performance-based contracts for heavy civil construction, forestry support activities, and professional technical services, often coordinating with field engineers and environmental specialists to define technical requirements and performance metrics. Langston maintains a consistent working relationship with McKenzie Construction & Site Development LLC, a key vendor delivering site development and infrastructure services aligned with forest road and bridge maintenance objectives. Her procurement patterns reflect collaborative, long-term vendor partnerships grounded in proven performance and compliance with environmental and safety standards. She prioritizes vendors with demonstrated expertise in hazardous tree removal, reforestation site preparation, and erosion control, fostering reliable supply chains for mission-critical field operations. Her contracting approach reflects a strong emphasis on small business participation, with over 25% of awards designated as Total Small Business Set-Asides under FAR 19.5 and a notable 3.7% allocated to HUBZone firms. While the majority of acquisitions remain open to all competitors, Langston actively structures solicitations to maximize opportunities for small, disadvantaged, and community-based contractors capable of delivering localized, sustainable solutions. Her primary procurement focus centers on NAICS codes 237310 (Highway, Street, and Bridge Construction), 237990 (Other Heavy and Civil Engineering Construction), and 115310 (Support Activities for Forestry), with additional emphasis on 541990 for specialized technical services. She specializes in acquiring services related to forest infrastructure maintenance, ecological restoration, and environmental compliance, demonstrating deep domain expertise in the intersection of civil engineering and natural resource management.
