R. J. ZAVORAL & SONS, INC.

R. J. Zavoral & Sons, Inc. specializes in heavy and civil engineering construction, with demonstrated experience in embankment and earthwork systems for defense infrastructure. Their core capabilities include the design and construction of large-scale earth retention structures, flood control embankments, and site grading for military installations. The firm applies precision earthmoving techniques, compaction control, and geotechnical alignment methods to deliver durable, mission-critical civil works. Their technical expertise centers on earthwork sequencing, drainage integration, and compliance with Army Corps of Engineers and DoD construction standards, ensuring structural integrity under dynamic load and environmental conditions. What sets them apart is their focus on precision earthwork execution in constrained or sensitive operational environments, where timing and accuracy directly impact mission readiness. The contractor has delivered work exclusively for the Department of Defense, specifically on military installation upgrades involving shoreline and flood protection infrastructure. Their engagement reflects a pattern of responsive, project-based support for U.S. Army and Defense Logistics Agency facilities requiring resilient earthwork solutions. This relationship underscores a niche positioning as a trusted subcontractor or prime for localized, high-precision civil construction tasks within defense bases. Their primary NAICS code, 237990, encompasses non-residential, large-scale civil infrastructure projects beyond standard road or building construction—such as levees, retaining walls, and embankment systems. This positions them within the defense and federal civil works vertical, serving agencies that require robust, long-term earth structures to safeguard critical assets. They are not engaged in general construction or building trades but focus narrowly on engineered earth systems. R. J. Zavoral & Sons, Inc. is a small, locally based firm headquartered in East Grand Forks, Minnesota, operating as a limited liability entity without federal certifications. Their market presence is regional but strategically aligned with DoD infrastructure needs in the Upper Midwest, leveraging proximity to military installations and federal engineering projects. They operate as a nimble, hands-on contractor focused on execution excellence in heavy civil earthworks.
