KAMEX, INC.

Kamadulski Excavating and Grading Company, Inc. specializes in heavy civil infrastructure construction with a focus on water and sewer line systems and complex earthwork operations. Their technical expertise includes precision grading, trenching, pipe laying, stormwater management, and utility relocation within constrained environments, often under demanding military site conditions. The firm demonstrates proficiency in executing phase-based construction tasks for critical public works, including sewer separation initiatives and military infrastructure upgrades, requiring strict adherence to geotechnical specifications, subsurface utility coordination, and environmental compliance. Their ability to deliver complex earthmoving and linear construction projects under tight operational timelines sets them apart in the defense and civil engineering sectors. The company maintains a consistent relationship with the Department of Defense, delivering mission-critical infrastructure improvements such as sewer system modernizations and utility reconfigurations at military installations. Their work supports base resilience and compliance with DoD environmental and operational standards, indicating a track record of performing sensitive, security-conscious construction in active duty environments. Kamadulski’s primary industry focus lies in NAICS 237110 for water and sewer line construction and NAICS 237990 for other heavy and civil engineering projects. These codes reflect hands-on execution of underground utility networks, drainage systems, and site preparation for large-scale facilities. The firm is positioned as a niche contractor in defense-adjacent civil works, emphasizing durable, long-life infrastructure rather than commercial or residential development. As a small business structured as a 2L entity based in Granite City, Illinois, Kamadulski operates regionally with deep local knowledge of Midwestern geotechnical conditions. While no federal certifications are listed, their consistent performance on DoD contracts demonstrates reliability and regulatory familiarity. Their geographic presence supports efficient mobilization across the Midwest, making them a dependable partner for infrastructure projects requiring rapid response and proven field execution.
