Marcena Blackwell

Marcena Blackwell serves as a key procurement lead within the W076 Endist Tulsa office under the Department of the Army, overseeing the acquisition of facility support services critical to sustaining Army installations and public lands. Responsible for managing contract execution aligned with the agency’s mission of infrastructure modernization and environmental compliance, Blackwell specializes in janitorial and facility operations contracts that ensure regulatory adherence, operational readiness, and public health standards. Their procurement portfolio is narrowly focused on service-based acquisitions essential to the daily functioning of military facilities, with an emphasis on cleanliness, waste management, and environmental sanitation services. Blackwell maintains consistent working relationships with a select group of established contractors including BL HARBERT INTERNATIONAL LLC, MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, ALBERICI CONSTRUCTORS INC, MCMILLEN, INC., and PERIKIN ENTERPRISES LLC. These partnerships reflect a preference for vendors with proven experience in federal facility services, particularly those capable of delivering scalable, compliant janitorial and site maintenance solutions across diverse geographic locations. The contracting approach emphasizes reliability, performance-based outcomes, and long-term vendor stability to support continuous operations on active military installations. All procurements managed by Blackwell are structured as total small business set-asides under FAR 19.5, demonstrating an unwavering commitment to socioeconomic contracting goals. This policy ensures that every contract opportunity is reserved exclusively for small businesses, fostering equitable access to federal work and promoting economic growth within underserved communities. The agency’s full reliance on small business set-asides underscores a strategic effort to build a resilient, diverse contractor base capable of meeting mission-critical service demands. The procurement focus is exclusively on NAICS 561720 — Janitorial Services — encompassing everything from routine custodial operations to specialized environmental sanitation and hazardous waste support. Blackwell’s expertise lies in defining performance metrics, evaluating service quality standards, and ensuring compliance with federal environmental and safety regulations. Their work directly supports the Army’s infrastructure resilience by maintaining clean, safe, and compliant facilities essential to troop readiness and public land stewardship.
