Sina C. Sullivan serves as a Contract Specialist with the W076 Endist Tulsa under the Department of the Army, responsible for managing the full lifecycle of construction and engineering acquisitions to support military infrastructure modernization. Her role centers on ensuring compliance with federal procurement regulations while advancing the agency’s mission to sustain and enhance civil engineering, environmental, and facility operations across Army installations. She routinely handles complex contracts for commercial and institutional building construction, heavy civil works, and related technical services, balancing operational readiness with environmental stewardship and regulatory adherence. Sullivan maintains consistent working relationships with a core group of experienced contractors including BL Harbert International LLC, McMillen, Inc., Alberici Constructors Inc., McKenzie Construction & Site Development LLC, and Perikin Enterprises LLC. These partnerships reflect a preference for firms with proven expertise in heavy construction, facility maintenance, and infrastructure rehabilitation. Her procurement approach emphasizes performance-based outcomes, rigorous contract administration, and long-term vendor reliability, fostering collaborative relationships grounded in technical competence and compliance. A strong advocate for small business participation, Sullivan consistently prioritizes Total Small Business Set-Asides under FAR 19.5, with nearly 80% of her acquisitions reserved for small businesses. This pattern underscores a deliberate commitment to socioeconomic contracting goals, ensuring equitable access for small, disadvantaged, and locally rooted contractors in the delivery of critical infrastructure services across Army installations. Her primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), complemented by significant activity in heavy civil engineering (237990), plumbing and HVAC systems (238220), and engineering services (541330). She specializes in procuring integrated construction solutions that support facility sustainment, utility infrastructure upgrades, and environmental compliance projects, demonstrating deep technical familiarity with Army installation requirements and construction standards.
