Tamaron Calloway

Tamaron Calloway serves as a key procurement professional within the Great Plains Regional Office of the Bureau of Reclamation, overseeing the acquisition of critical infrastructure support services and specialized equipment essential to the agency’s water resource management mission. Responsible for planning, soliciting, and awarding contracts under federal acquisition regulations, Calloway ensures alignment with the Bureau’s strategic goals of modernizing water conveyance systems, hydropower facilities, and civil works infrastructure. Their portfolio primarily includes service-based and technical procurement actions supporting environmental compliance, facility maintenance, and engineering support, with a strong emphasis on regulatory adherence and mission-critical delivery. Calloway maintains a focused relationship with McKenzie Construction & Site Development LLC, a primary contractor delivering site development and civil construction services aligned with water infrastructure projects. While the majority of awards flow through this single vendor, Calloway also engages a small, diversified pool of niche suppliers to meet specialized technical needs. The working relationship reflects a pattern of repeat engagement with proven performers, emphasizing reliability, compliance, and performance history over broad competition, while still maintaining open solicitation practices to ensure market fairness. Calloway demonstrates a pronounced commitment to small business participation, with 60% of procurements structured as total small business set-asides under FAR 19.5. This reflects a deliberate strategy to foster economic opportunity within the region by prioritizing small, locally based vendors. While no other socioeconomic set-asides (e.g., 8(a), HUBZone, SDVOSB) dominate the portfolio, the consistent use of small business set-asides underscores a dedication to broad-based vendor inclusion and community economic development. The procurement focus centers on NAICS 562111 (Solid Waste Collection) and 562211 (Hazardous Waste Treatment and Disposal), indicating active environmental remediation and waste management initiatives tied to infrastructure operations. Additional emphasis on 333998 (Miscellaneous Machinery) and 334412 (Bare Printed Circuit Board Manufacturing) reveals procurement of specialized control systems and instrumentation for hydropower and water monitoring infrastructure. This blend of environmental services and technical manufacturing support highlights expertise in managing complex, mission-critical supply chains for federal water resource infrastructure.
