Cassidy Bigham

Cassidy Bigham serves as a primary contracting professional within Navfacsyscom Southeast, responsible for managing the acquisition of mission-critical infrastructure projects across the Southeastern U.S. and overseas operational areas. In this role, Bigham executes full lifecycle procurement actions for complex civil engineering and construction contracts aligned with the Department of the Navy’s readiness objectives. Their work centers on the planning, design, and construction of military facilities, utilities systems, and base operations infrastructure, ensuring compliance with federal acquisition regulations and mission-driven delivery standards. Bigham routinely handles large-scale, competitively bid contracts under the Other Heavy and Civil Engineering Construction NAICS code, coordinating with design teams, project managers, and field engineers to align contractual requirements with operational needs. Bigham maintains consistent working relationships with a core group of experienced federal construction contractors, including BL Harbert International LLC, Walsh Federal LLC, Sauer Construction, LLC, McKenzie Construction & Site Development LLC, and Kira Aviation Services LLC. These partnerships reflect a preference for firms with proven track records in heavy civil works, military construction, and aviation support infrastructure. The contracting approach emphasizes performance-based outcomes, rigorous quality control, and adherence to safety and environmental compliance standards, fostering long-term vendor collaboration grounded in reliability and technical proficiency. Bigham’s procurement portfolio reflects a 100% non-set-aside strategy, with no reliance on 8(a), HUBZone, SDVOSB, or other socioeconomic set-asides. All acquisitions are conducted under full and open competition, prioritizing technical capability, past performance, and cost-effectiveness over socioeconomic classifications. This approach underscores a mission-first procurement philosophy focused on delivering resilient infrastructure through the most qualified industry partners. The primary technical domain is NAICS 237990—Other Heavy and Civil Engineering Construction—encompassing large-scale earthwork, roadways, airfields, water and wastewater systems, and other civil infrastructure essential to naval installations. Bigham’s expertise lies in procuring turnkey construction solutions requiring advanced engineering, geotechnical analysis, and compliance with military construction standards.
