Maribel Ruble

Maribel Ruble serves as the primary procurement lead for the Lower Colorado Regional Office of the Bureau of Reclamation, overseeing the acquisition of critical infrastructure services essential to sustaining water supply reliability and environmental compliance across arid region systems. She manages a diverse portfolio of construction and engineering contracts aligned with the agency’s mission to modernize water infrastructure, ensure operational resilience, and uphold environmental standards. Her acquisitions typically involve heavy civil engineering, site preparation, and utility system upgrades, requiring rigorous adherence to federal contracting regulations and technical specifications for public works projects. Ruble maintains consistent working relationships with key contractors including KWR Construction Inc., McKenzie Construction & Site Development LLC, Laz Parking Ltd., LLC, Flint Farms, LLC, and GreenHeart Farms, Inc. These partnerships reflect a balanced mix of general contractors, specialized site developers, and agricultural service providers engaged in infrastructure support, land management, and facility maintenance. Her procurement approach emphasizes reliability, technical competence, and long-term performance, fostering collaborative vendor relationships grounded in compliance and project-specific expertise. Her contracting patterns demonstrate a strong preference for open competition, with 60% of awards issued without set-aside designations. Nevertheless, she actively supports small business participation, allocating nearly 40% of awards to small business set-asides, including Total Small Business, HUBZone, and Women-Owned Small Business categories. This balanced strategy ensures competitive pricing while promoting socioeconomic equity in federal contracting. Ruble’s primary technical focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction) and 237310 (Highway, Street, and Bridge Construction), with significant activity in electrical, plumbing, and site preparation contracting. She procures services related to dam maintenance, irrigation system upgrades, flood control structures, and ancillary infrastructure, requiring deep familiarity with Bureau of Reclamation engineering standards and environmental mitigation protocols. Her expertise ensures that acquisitions directly advance the agency’s mission of sustainable water resource management.
