KOLB GRADING, LLC

KOLB GRADING, LLC specializes in site preparation and earthmoving services for public infrastructure projects, with deep expertise in land grading, excavation, drainage installation, and compaction work aligned with federal and state civil construction standards. The company applies precision earthwork techniques using heavy equipment and survey-grade grading controls to ensure compliance with topographic specifications and erosion control requirements. Their technical capabilities include cut-and-fill optimization, subgrade stabilization, and stormwater management system integration, all performed under strict environmental and safety protocols. As a Woman-Owned Business, KOLB GRADING brings a focused commitment to quality execution and operational accountability in high-stakes public works environments. Award history does not provide sufficient detail to identify specific federal agencies or recurring project types, so direct agency relationships cannot be confirmed. However, given their primary NAICS classification of 238910 — Other Heavy and Civil Engineering Construction — their work likely supports transportation, water resource, and public facility development initiatives typically managed by DOTs, Corps of Engineers, or GSA-affiliated civil works programs. The contractor’s industry focus centers on heavy civil construction, particularly earthwork and site development for government-funded infrastructure. This includes preparation of foundations for roads, utilities, and public buildings, with an emphasis on meeting ASTM and AASHTO standards for soil compaction and grading tolerances. Their market positioning is that of a specialized subcontractor or prime contractor in the civil construction supply chain, serving projects requiring exacting earthmoving precision and regulatory compliance. KOLB GRADING, LLC is a small, locally based entity headquartered in Weldon Spring, Missouri, structured as a 2L (small business) with Woman-Owned Business certification. The company operates regionally within the Midwest, leveraging its certification to compete for set-aside contracts while maintaining a reputation for reliable, on-time execution in civil construction markets.
